Part 11

The car ran on through the night, with great, unblinking lights staring straight out ahead on a road as smooth as asphalt. The turn was made, then more slowly the car proceeded along the cross road. At the second house, dimly discernible through the night, The Thinking Machine gave the signal to stop.

Hatch leaped out, and The Thinking Machine followed. Together they approached the house, a small cottage some distance back from the road. As they went up the path they came upon another automobile, but it had no lights and the engine was still.

Even in the darkness they could see that one of the forward wheels was gone, and the front of the car was demolished.

"That fellow had a bad accident," Hatch remarked.

An old woman and a boy appeared at the door in answer to their rap.

"I am looking for a gentleman who was injured last night in an automobile accident," said The Thinking Machine. "Is he still here?"

"Yes. Come in."

They stepped inside as a man's voice called from another room:

"Who is it?"

"Two gentlemen to see the man who was hurt," the woman called.

"Do you know his name?" asked The Thinking Machine.

"No, sir," the woman replied. Then the man who had spoken appeared.

"Would it be possible for us to see the gentleman who was hurt?" asked The Thinking Machine.

"Well, the doctor said we would have to keep folks away from him," was the reply. "Is there anything I could tell you?"

"We would like to know who he is," said The Thinking Machine. "It may be that we can take him off your hands."

"I don't know his name," the man explained; "but here are the things we took off him. He was hurt on the head, and hasn't been able to speak since he was brought here."

The Thinking Machine took a gold watch, a small notebook, two or three cards of various business concerns, two railroad tickets to New York and one thousand dollars in large bills. He merely glanced at the papers. No name appeared anywhere on them; the same with the railroad tickets. The business cards meant nothing at the moment. It was the gold watch on which the scientist concentrated his attention. He looked on both sides, then inside, carefully. Finally he handed it back.

"What time did this gentleman come here?" he asked.

"We brought him in from the road about nine o'clock," was the reply. "We heard his automobile smash into something and found him there beside it a moment later. He was unconscious. His car had struck a stone on the curve and he was thrown out head first."

"And where is his wife?"

"His wife?" The man looked from The Thinking Machine to the woman. "His wife? We didn't see anybody else."

"Nobody ran away from the machine as you went out?" insisted the scientist.

"No, sir," was the positive reply.

"And no woman has been here to inquire for him?"

"No, sir."

"Has anybody?"

"No, sir."

"What direction was the car going when it struck?"

"I couldn't tell you, sir. It had turned entirely over and was in the middle of the road when we found it."

"What's the number of the car?"

"It didn't have any."

"This gentleman has good medical attention, I suppose?"

"Yes, sir. Dr. Leonard is attending him. He says his condition isn't dangerous, and meanwhile we're letting him stay here, because we suppose he'll make it all right with us when he gets well."

"Thank you--that's all," said The Thinking Machine. "Good-night."

With Hatch he turned and left the house. "What is all this?" asked Hatch, bewildered. "That man is Morgan Mason," said The Thinking Machine.

"The man who eloped with Miss Dow?" asked Hatch, breathlessly.

"Now, where is Miss Dow?" asked The Thinking Machine, in turn.

"You mean----"

The Thinking Machine waved his hand off into the vague night; it was a gesture which Hatch understood perfectly.

V.

Hutchinson Hatch was deeply thoughtful on the swift run back to the village. There he and The Thinking Machine took train to Boston. Hatch was turning over possibilities. Had Miss Dow eloped with some one besides Mason? There had been no other name mentioned. Was it possible that she killed Miss Melrose? Vaguely his mind clutched for a motive for this, yet none appeared, and he dismissed the idea with a laugh at its absurdity. Then, What? Where? How? Why?

"I suppose the story of an actress having been murdered in an automobile under mysterious circumstances would have been telegraphed all over the country, Mr. Hatch?" asked The Thinking Machine.

"Yes," said Hatch. "If you mean this story, there's not a city in the country that doesn't know of it by this time."

"It's perfectly wonderful, the resources of the press," the scientist mused.

Hatch nodded his acquiescence. He had hoped for a moment that The Thinking Machine had asked the question as a preliminary to something else, but that was apparently all. After awhile the train jerked a little and The Thinking Machine spoke again.

"I think, Mr. Hatch, I wouldn't yet print anything about the disappearance of Miss Dow," he said. "It might be unwise at present. No one else will find it out, so----"

"I understand," said Hatch. It was a command. "By the way," the other went on, "do you happen to remember the name of that Winter Street store that Curtis went in?"

"Yes," and he named it.

It was nearly midnight when The Thinking Machine and Hatch reached Boston. The reporter was dismissed with a curt:

"Come up at noon to-morrow."

Hatch went his way. Next day at noon promptly he was waiting in the reception room of The Thinking Machine's home. The scientist was out--down in Winter Street, Martha explained--and Hatch waited impatiently for his return. He came in finally.

"Well?" inquired the reporter.

"Impossible to say anything until day after to-morrow," said The Thinking Machine.

"And then?" asked Hatch.

"The solution," replied the scientist positively. "Now I'm waiting for some one."

"Miss Dow?"

"Meanwhile you might see Reid and find out in some way if he ever happened to make a gift of any little thing, a thing that a woman would wear on the outside of her coat, for instance, to Miss Dow."

"Lord, I don't think _he'll_ say anything."

"Find out, too, when he intends to go back West."

It took Hatch three hours, and required a vast deal of patience and skill, to find out that on a recent birthday Miss Dow had received a present of a monogram belt buckle from Reid. That was all; and that was not what The Thinking Machine meant. Hatch had the word of Miss Dow's maid for it that while Miss Dow wore this belt at the time of her elopement, it was underneath the automobile coat.

"Have you heard anything more from Miss Dow?" asked Hatch.

"Yes," responded the maid. "Her father received a letter from her this morning. It was from Chicago, and said that she and her husband were on their way to San Francisco and that the family might not hear from them again until after the honeymoon."

"How? What?" gasped Hatch. His brain was in a muddle. "She in Chicago, _with--her husband?_"

"Yes, sir."

"Is there any question about the letter being in her handwriting?"

"Not at all," replied the maid, positively. "It's perfectly natural," she concluded.

"But----" Hatch began, then he stopped.

For one fleeting instant he was tempted to tell the maid that the man whom the family had supposed was Miss Dow's husband was lying unconscious at a farmhouse not a great way from the Monarch Inn, and that there was no trace of Miss Dow. Now this letter! His head whirled when he thought of it.

"Is there any question but that Miss Dow did elope with Mr. Mason and not some other man?" he asked.

"It was Mr. Mason, all right," the girl responded. "I knew there was to be an elopement and helped arrange for Miss Dow to go," she added, confidentially. "It was Mr. Mason, I know."

Then Hatch rushed away and telephoned to The Thinking Machine. He simply couldn't hold this latest development until he saw him again.

"We've made a mistake," he bellowed through the 'phone.

"What's that?" demanded The Thinking Machine, aggressively.

"Miss Dow is in Chicago with her husband--family has received a letter from her--that man out there with the smashed head can't be Mason," the reporter explained hurriedly.

"Dear me, dear me!" said The Thinking Machine over the wire. And again: "Dear me!"

"Her maid told me all about it," Hatch rushed on, "that is, all about her aiding Miss Dow to elope, and all that. Must be some mistake."

"Dear me!" again came in the voice of The Thinking Machine. Then: "Is Miss Dow a blonde or brunette?"

The irrelevancy of the question caused Hatch to smile in spite of himself.

"A brunette," he answered. "A pronounced brunette."

"Then," said The Thinking Machine, as if this were merely dependent upon or a part of the blonde or brunette proposition, "get immediately a picture of Mason somewhere--I suppose you can--go out and see that man with the smashed head and see if it is Mason. Let me know by 'phone."

"All right," said Hatch, rather hopelessly. "But it is impossible----"

"Don't say that," snapped The Thinking Machine. "Don't say that," he repeated, angrily. "It annoys me exceedingly."

It was nearly ten o'clock that night when Hatch again 'phoned to The Thinking Machine. He had found a photograph, he had seen the man with the smashed head. They were the same. He so informed The Thinking Machine.

"Ah," said that individual, quietly. "Did you find out about any gift that Reid might have made to Miss Dow?" he asked.

"Yes, a monogram belt buckle of gold," was the reply.

Hatch was over his head and knew it. He was finding out things and answering questions, which by the wildest stretch of his imagination, he could not bring to bear on the matter in hand--the mystery surrounding the murder of Marguerite Melrose, an actress.

"Meet me at my place here at one o'clock day after to-morrow," instructed The Thinking Machine. "Publish as little as you can of this matter until you see me. It's extraordinary--perfectly extraordinary. Good-by."

That was all. Hatch groped hopelessly through the tangle, seeking one fact that he could grasp. Then it occurred to him that he had never ascertained when Reid intended to return West, and he went to the Hotel Teutonic for this purpose. The clerk informed him that Reid was to start in a couple of days. Reid had hardly left his room since Curtis was locked up.

Precisely at one o'clock on the second day following, as directed by The Thinking Machine, Hatch appeared and was ushered in. The Thinking Machine was bowed over a retort in his laboratory, and he looked up at the reporter with a question in his eyes.

"Oh, yes," he said, as if recollecting for the first time the purpose of the visit. "Oh, yes."

He led the way to the reception room and gave instructions to Martha to admit whoever inquired for him; then he sat down and leaned back in his chair. After awhile the bell rang and two men were shown in. One was Charles Reid; the other a detective whom Hatch knew.

"Ah, Mr. Reid," said The Thinking Machine. "I'm sorry to have troubled you, but there were some questions I wanted to ask before you went away. If you'll wait just a moment."

Reid bowed and took a seat.

"Is he under arrest?" Hatch inquired of the detective, aside.

"Oh, no," was the reply. "Oh, no. Detective Mallory told me to ask him to come up. I don't know what for."

After awhile the bell rang again. Then Hatch heard Detective Mallory's voice in the hall and the rustle of skirts; then the voice of another man. Mallory appeared at the door after a moment; behind him came two veiled women and a man who was a stranger to Hatch.

"I'm going to make a request, Mr. Mallory," said The Thinking Machine. "I know it will be a cause of pleasure to Mr. Reid. It is that you release Mr. Curtis, who is charged with the murder of Miss Melrose."

"Why?" demanded Mallory, quickly. Hatch and Reid stared at the scientist curiously.

"This," said The Thinking Machine.

The two women simultaneously removed their veils.

One was Miss Marguerite Melrose.

VI.

"Miss Melrose that was," explained The Thinking Machine, "now Mrs. Donald MacLean. This, gentlemen, is her husband. This other young woman is Miss Dow's maid. Together I believe we will be able to throw some light on the death of the young woman who was found in Mr. Curtis's automobile."

Stupefied with amazement, Hatch stared at the woman whose reported murder had startled and puzzled the entire country. Reid had shown only slight emotion--an emotion of a kind hard to read. Finally he advanced to Miss Melrose, or Mrs. MacLean, with outstretched hand.

"Marguerite," he said.

The girl looked deeply into his eyes, then took the proffered hand.

"And Jack Curtis?" she asked.

"If Detective Mallory will have him brought here we can immediately end his connection with this case so far as your murder is concerned," said The Thinking Machine.

"Who--who was murdered, then?" asked Hatch. "A little circumstantial development is necessary to show," replied The Thinking Machine.

Detective Mallory retired into another room and 'phoned to have Curtis brought up. On his assurance that there had been a mistake which he would explain later, Curtis set out from his cell with a detective and within a few minutes appeared in the room, wonderingly.

One look at Marguerite and he was beside her, gripping her hand. For a time he didn't speak; it was not necessary. Then the actress, with flushed face, indicated MacLean, who had stood quietly by, an interested but silent spectator.

"My husband, Jack," she said.

Quick comprehension swept over Curtis and he looked from one to another. Then he approached MacLean with outstretched hand.

"I congratulate you," he said, with deep feeling. "Make her happy."

Reid had stood unobserved meanwhile. Hatch's glance traveled from one to another of the persons in the room. He was seeking to explain that expression on Reid's face, vainly thus far. There was a little pause as Reid and Curtis came face to face, but neither spoke.

"Now, please, what does it all mean?" asked MacLean, who up to this time had been silent.

"It's a strange study of the human brain," said The Thinking Machine, "and incidentally a little proof that circumstantial evidence is absolutely worthless. For instance, here it was proven that Miss Melrose was dead, that Mr. Curtis was jealous of her, that while drinking he had threatened her--this I learned at the Hotel Yarmouth, but now it is unimportant--that his knife killed her, and finally that there was blood on one of his handkerchiefs. This is the complete circumstantial chain; and Miss Melrose appears, alive.

"Suppose we take the case from the point where I entered it. It will be interesting as showing the methods of a brain which reduces all things to tangible strands which may be woven into a whole, then fitting them together. My knowledge of the affair began when Mr. Curtis was brought to these apartments by Mr. Hatch. Mr. Curtis was ill. I gave him a stimulant; he aroused suddenly and shrieked: 'I saw her. There was a dagger in her heart. Marguerite!'

"My first impression was that he was insane; my next that he had delirium tremens, because I saw he had been drinking heavily. Later I saw it was temporary mental collapse due to excessive drinking and a tremendous strain. Instantly I associated Marguerite with this--'a dagger in her heart.' Therefore, Marguerite dead or wounded. 'I saw her.' Dead or alive? These, then, were my first impressions.

"I asked Mr. Hatch what had happened. He told me Miss Melrose, an actress, had been murdered the night before. I suggested suicide, because suicide is always the first possibility in considering a case of violent death which is not obviously accidental. He insisted that he believed it was murder, and told me why. It was all he knew of the story.

"There was the stopping of The Green Dragon at the Monarch Inn for gasoline; the disappearance Of Mr. Curtis, as he told the police, to hunt for gasoline--partly proven by the fact that he brought it back; the statement of Mr. Reid to the police that he had gone into the inn for a hot Scotch, and confirmation of this. Above all, here was the opportunity for the crime--if it were committed by any person other than Curtis or Reid.

"Then Mr. Hatch repeated to me the statement made to him by Dr. Leonard. The first thing that impressed me here was the fact that Curtis had, in taking the girl into the house, carried her by the shoulders. Instantly I saw, knowing that the girl had been stabbed through the heart, how it would be possible for blood to get on Mr. Curtis's hands, thence on his handkerchief or clothing. This was before I knew or considered his connection with the death at all.

"Curtis told Dr. Leonard that the girl was Miss Melrose. The body wasn't yet cold, therefore death must have come just before it reached the doctor. Then the knife was discovered. Here was the first tangible working clew--a rough knife, with a blade six or seven inches long. Obviously not the sort of knife a woman would carry about with her. Therefore, where did it come from?

"Curtis tried to induce the doctor to let him have the knife; probably Curtis's knife, possibly Reid's. Why Curtis's? The nature of the knife, a blade six or seven inches long, indicated a knife used for heavy work, not for a penknife. Under ordinary circumstances such a knife would not have been carried by Reid; therefore it may have belonged to Curtis's auto kit. He might have carried it in his pocket.

"Thus, considering _that it was Miss Melrose who was dead_, we had these facts: Dead only a few minutes, possibly stabbed while the two men were away from the car; Curtis's knife used--not a knife from any other auto kit, mind you, _because Curtis recognized this knife_. Two and two make four, not sometimes, but all the time."

Every person in the room was leaning forward, eagerly listening; Reid's face was perfectly white. The Thinking Machine finally arose, walked over and ran his fingers through Reid's hair, then sat again squinting at the ceiling. He spoke as if to himself.

"Then Mr. Hatch told me another important thing," he went on. "At the moment it appeared a coincidence, later it assumed its complete importance. This was that Dr. Leonard did not actually see the face of the 'girl--only the chin; that the hair was covered by a veil and the mask covered the remainder of the face. Here for the first time I saw that it was wholly possible that the woman _was not Miss Melrose at all_. I saw it as a possibility; not that I believed it. I had no reason to, then.

"The dress of the young woman meant nothing; it was that of thousands of other young women who go automobiling--handsome tailor-made gown, tan dust coat. Then I tricked Mr. Curtis--I suppose it is only fair to use the proper word--into telling me his story by making him believe he made compromising admissions while unconscious. I had, I may say, too, examined his head minutely. I have always maintained that the head of a murderer will show a certain indentation. Mr. Curtis's head did not show this indentation, neither does Mr. Reid's.

"Mr. Curtis told me the first thing to show that the knife which killed the girl--I still believed her Miss Melrose then--could have passed out of his hands. He said when he leaped from the automobile he thought he dropped something, searched for it a moment, failed to find it, then, being in a hurry, went on. He called back to Mr. Reid to search for what he had lost. That is when Mr. Curtis lost the knife; that is when it passed into the possession of Mr. Reid. He found it."

Every eye was turned on Reid. He sat as if fascinated, staring into the upward turned face of the scientist.

"There we had a girl--presumably Miss Melrose--dead, by a knife owned by Mr. Curtis, last in the possession of Mr. Reid. Mr. Hatch had previously told me that the medical examiner said the wound which killed the girl came from her right, in a general direction. Therefore here was a possibility that Mr. Reid did it in the automobile--a possibility, I say.

"I asked Mr. Curtis why he tried to recover the knife from Dr. Leonard. He stammered and faltered, but really it was because, having recognized the knife, he was afraid the crime would come home to him. Mr. Curtis denied flatly that the knife was his, and in denying told me that it was. It was not Mr. Reid's I was assured. Mr. Curtis also told me of his love for Miss Melrose, but there was nothing there, as it appeared, strong enough to suggest a motive for murder. He mentioned you, Mr. MacLean, then.

"Then Mr. Curtis named Miss Dow as one whose hand had been sought by Mr. Reid. Mr. Hatch told me this girl--Miss Dow--had eloped the night before with Morgan Mason from Monarch Inn--or, to be exact, that her family had received a letter from her stating that she was eloping; that Mason had taken out a marriage license. Remember this was the girl that Reid was in love with; it was singular that there should have been a Monarch Inn end to that elopement as well as to this tragedy.

"This meant nothing as bearing on the abstract problem before me until Mr. Curtis described Miss Melrose as having golden hair. With another minor scrap of information Mr. Hatch again opened up vast possibilities by stating that the medical examiner, a careful man, had said Miss Melrose had dark hair. I asked him if he had seen the body; he had not. But the medical examiner told him that. Instantly in my mind the question was aroused: Was it _Miss Melrose_ who was killed? This was merely a possibility; it still had no great weight with me.

"I asked Mr. Curtis as to the circumstances which caused his collapse in Winter Street. He explained it was because he had seen a woman whom he would have sworn was Miss Melrose if he had not known that she was dead. This, following the dark hair and blonde hair puzzle, instantly caused this point to stand forth sharply in my mind. Was Miss Melrose dead at all? I had good reason then to believe that she was _not_.

"Previously, with the idea of fixing for all time the ownership of the knife--yet knowing in my own mind it was Mr. Curtis's--I had sent for Mr. Reid. I told him Mr. Curtis had said it was his knife. Mr. Reid fell into the trap and did the very thing I expected. He declared angrily the knife was Mr. Curtis's, thinking Curtis had tried to saddle the crime on him. Then I turned Mr. Curtis over to the police. When he was locked up I was reasonably certain that he did not commit any crime, because I had traced the knife from him to Mr. Reid."

There was a glitter in Reid's eyes now. It was not fear, only a nervous battle to restrain himself. The Thinking Machine went on:

"I saw the body of the dead woman--indeed, assisted at her autopsy. She was a pronounced brunette--Miss Melrose was a blonde. The mistake in identity was not an impossible one in view of the fact that each wore a mask and had her hair tied up under a veil. That woman was stabbed from the right--still a possibility of suicide."

"Who was the woman?" demanded Curtis. He seemed utterly unable to control himself longer.

"Miss Elizabeth Dow, who was supposed to have eloped with Morgan Mason," was the quiet reply.

Instant amazement was reflected on every face save Reid's, and again every eye was turned to him. Miss Dow's maid burst into tears.

"Mr. Reid knew who the woman was all the time," said The Thinking Machine. "Knowing then that Miss Dow was the dead woman--this belief being confirmed by a monogram gold belt buckle, 'E. D.,' on the body--I proceeded to find out all I could in this direction. The waiters had seen Mr. Reid in the inn; had seen him talking to a masked and veiled lady who had been waiting for nearly an hour; had seen him go into a room with her, but had not seen them leave the inn. Mr. Reid had recognized the lady--not she him. How? By a glimpse of the monogram belt buckle which he knew because he probably gave it to her."

"He did," interposed Hatch.
