Chapter 9

“Mrs. Pitts,” replied Kennedy quickly, observing still the play of emotion on her delicate features, “some one, I believe, either regularly in or employed in this house or who had a ready means of access to it must have entered that kitchen last night. For what purpose, I can leave you to judge. But Sam surprised the intruder there and was killed for his faithfulness.”

Her startled look told plainly that though she might have suspected something of the sort she did not think that any one else suspected, much less actually perhaps knew it.

“I can’t imagine who it could be, unless it might be one of the servants,” she murmured hastily; adding, “and there is none of them that I have any right to suspect.”

She had in a measure regained her composure, and Kennedy felt that it was no use to pursue the conversation further, perhaps expose his hand before he was ready to play it.

“That woman is concealing something,” remarked Kennedy to me as we left the house a few minutes later.

“She at least bears no marks of violence herself of any kind,” I commented.

“No,” agreed Craig, “no, you are right so far.” He added: “I shall be very busy in the laboratory this afternoon, and probably longer. However, drop in at dinner time, and in the meantime, don’t say a word to any one, but just use your position on the Star to keep in touch with anything the police authorities may be doing.”

It was not a difficult commission, since they did nothing but issue a statement, the net import of which was to let the public know that they were very active, although they had nothing to report.

Kennedy was still busy when I rejoined him, a little late purposely, since I knew that he would be over his head in work.

“What’s this—a zoo?” I asked, looking about me as I entered the sanctum that evening.

There were dogs and guinea pigs, rats and mice, a menagerie that would have delighted a small boy. It did not look like the same old laboratory for the investigation of criminal science, though I saw on a second glance that it was the same, that there was the usual hurly-burly of microscopes, test-tubes, and all the paraphernalia that were so mystifying at first but in the end under his skilful hand made the most complicated cases seem stupidly simple.

Craig smiled at my surprise. “I’m making a little study of intestinal poisons,” he commented, “poisons produced by microbes which we keep under more or less control in healthy life. In death they are the little fellows that extend all over the body and putrefy it. We nourish within ourselves microbes which secrete very virulent poisons, and when those poisons are too much for us—well, we grow old. At least that is the theory of Metchnikoff, who says that old age is an infectious chronic, disease. Somehow,” he added thoughtfully, “that beautiful white kitchen in the Pitts home had really become a factory for intestinal poisons.”

There was an air of suppressed excitement in his manner which told me that Kennedy was on the trail of something unusual.

“Mouth murder,” he cried at length, “that was what was being done in that wonderful kitchen. Do you know, the scientific slaying of human beings has far exceeded organised efforts at detection? Of course you expect me to say that; you think I look at such things through coloured glasses. But it is a fact, nevertheless.

“It is a very simple matter for the police to apprehend the common murderer whose weapon is a knife or a gun, but it is a different thing when they investigate the death of a person who has been the victim of the modern murderer who slays, let us say, with some kind of deadly bacilli. Authorities say, and I agree with them, that hundreds of murders are committed in this country every year and are not detected because the detectives are not scientists, while the slayers have used the knowledge of the scientists both to commit and to cover up the crimes. I tell you, Walter, a murder science bureau not only would clear up nearly every poison mystery, but also it would inspire such a wholesome fear among would-be murderers that they would abandon many attempts to take life.”

He was as excited over the case as I had ever seen him. Indeed it was one that evidently taxed his utmost powers.

“What have you found?” I asked, startled.

“You remember my use of the sphygmomanometer?” he asked. “In the first place that put me on what seems to be a clear trail. The most dreaded of all the ills of the cardiac and vascular systems nowadays seems to be arterio-sclerosis, or hardening of the arteries. It is possible for a man of forty-odd, like Mr. Pitts, to have arteries in a condition which would not be encountered normally in persons under seventy years of age.

“The hard or hardening artery means increased blood pressure, with a consequent increased strain on the heart. This may lead, has led in this case, to a long train of distressing symptoms, and, of course, to ultimate death. Heart disease, according to statistics, is carrying off a greater percentage of persons than formerly. This fact cannot be denied, and it is attributed largely to worry, the abnormal rush of the life of to-day, and sometimes to faulty methods of eating and bad nutrition. On the surface, these natural causes might seem to be at work with Mr. Pitts. But, Walter, I do not believe it, I do not believe it. There is more than that, here. Come, I can do nothing more to-night, until I learn more from these animals and the cultures which I have in these tubes. Let us take a turn or two, then dine, and perhaps we may get some word at our apartment from Edward.”

It was late that night when a gentle tap at the door proved that Kennedy’s hope had not been unfounded. I opened it and let in Edward, the valet, who produced the fragments of a note, torn and crumpled.

“There is nothing new, sir,” he explained, “except that Mrs. Pitts seems more nervous than ever, and Mr. Pitts, I think, is feeling a little brighter.”

Kennedy said nothing, but was hard at work with puckered brows at piecing together the note which Edward had obtained after hunting through the house. It had been thrown into a fireplace in Mrs. Pitts’s own room, and only by chance had part of it been unconsumed. The body of the note was gone altogether, but the first part and the last part remained.

Apparently it had been written the very morning on which the murder was discovered.

It read simply, “I have succeeded in having Thornton declared ...” Then there was a break. The last words were legible, and were, “... confined in a suitable institution where he can cause no future harm.”

There was no signature, as if the sender had perfectly understood that the receiver would understand.

“Not difficult to supply some of the context, at any rate,” mused Kennedy. “Whoever Thornton may be, some one has succeeded in having him declared ‘insane,’ I should supply. If he is in an institution near New York, we must be able to locate him. Edward, this is a very important clue. There is nothing else.”

Kennedy employed the remainder of the night in obtaining a list of all the institutions, both public and private, within a considerable radius of the city where the insane might be detained.

The next morning, after an hour or so spent in the laboratory apparently in confirming some control tests which Kennedy had laid out to make sure that he was not going wrong in the line of inquiry he was pursuing, we started off in a series of flying visits to the various sanitaria about the city in search of an inmate named Thornton.

I will not attempt to describe the many curious sights and experiences we saw and had. I could readily believe that any one who spent even as little time as we did might almost think that the very world was going rapidly insane. There were literally thousands of names in the lists which we examined patiently, going through them all, since Kennedy was not at all sure that Thornton might not be a first name, and we had no time to waste on taking any chances.

It was not until long after dusk that, weary with the search and dust-covered from our hasty scouring of the country in an automobile which Kennedy had hired after exhausting the city institutions, we came to a small private asylum up in Westchester. I had almost been willing to give it up for the day, to start afresh on the morrow, but Kennedy seemed to feel that the case was too urgent to lose even twelve hours over.

It was a peculiar place, isolated, out-of-the-way, and guarded by a high brick wall that enclosed a pretty good sized garden.

A ring at the bell brought a sharp-eyed maid to the door.

“Have you—er—any one here named Thornton—er—?” Kennedy paused in such a way that if it were the last name he might come to a full stop, and if it were a first name he could go on.

“There is a Mr. Thornton who came yesterday,” she snapped ungraciously, “but you can not see him, It’s against the rules.”

“Yes—yesterday,” repeated Kennedy eagerly, ignoring her tartness. “Could I—” he slipped a crumpled treasury note into her hand—“could I speak to Mr. Thornton’s nurse?”

The note seemed to render the acidity of the girl slightly alkaline. She opened the door a little further, and we found ourselves in a plainly furnished reception room, alone.

We might have been in the reception-room of a prosperous country gentleman, so quiet was it. There was none of the raving, as far as I could make out, that I should have expected even in a twentieth century Bedlam, no material for a Poe story of Dr. Tarr and Professor Feather.

At length the hall door opened, and a man entered, not a prepossessing man, it is true, with his large and powerful hands and arms and slightly bowed, almost bulldog legs. Yet he was not of that aggressive kind which would make a show of physical strength without good and sufficient cause.

“You have charge of Mr. Thornton?” inquired Kennedy.

“Yes,” was the curt response.

“I trust he is all right here?”

“He wouldn’t be here if he was all right,” was the quick reply. “And who might you be?”

“I knew him in the old days,” replied Craig evasively. “My friend here does not know him, but I was in this part of Westchester visiting and having heard he was here thought I would drop in, just for old time’s sake. That is all.”

“How did you know he was here?” asked the man suspiciously.

“I heard indirectly from a friend of mine, Mrs. Pitts.”

“Oh.”

The man seemed to accept the explanation at its face value.

“Is he very—very badly?” asked Craig with well-feigned interest.

“Well,” replied the man, a little mollified by a good cigar which I produced, “don’t you go a-telling her, but if he says the name Minna once a day it is a thousand times. Them drug-dopes has some strange delusions.”

“Strange delusions?” queried Craig. “Why, what do you mean?”

“Say,” ejaculated the man. “I don’t know you, You come here saying you’re friends of Mr. Thornton’s. How do I know what you are?”

“Well,” ventured Kennedy, “suppose I should also tell you I am a friend of the man who committed him.”

“Of Dr. Thompson Lord?”

“Exactly. My friend here knows Dr. Lord very well, don’t you, Walter?”

Thus appealed to I hastened to add, “Indeed I do.” Then, improving the opening, I hastened: “Is this Mr. Thornton violent? I think this is one of the most quiet institutions I ever saw for so small a place.”

The man shook his head.

“Because,” I added, “I thought some drug fiends were violent and had to be restrained by force, often.”

“You won’t find a mark or a scratch on him, sir,” replied the man. “That ain’t our system.”

“Not a mark or scratch on him,” repeated Kennedy thoughtfully. “I wonder if he’d recognise me?”

“Can’t say,” concluded the man. “What’s more, can’t try. It’s against the rules. Only your knowing so many he knows has got you this far. You’ll have to call on a regular day or by appointment to see him, gentlemen.”

There was an air of finality about the last statement that made Kennedy rise and move toward the door with a hearty “Thank you, for your kindness,” and a wish to be remembered to “poor old Thornton.”

As we climbed into the car he poked me in the ribs. “Just as good for the present as if we had seen him,” he exclaimed. “Drug-fiend, friend of Mrs. Pitts, committed by Dr. Lord, no wounds.”

Then he lapsed into silence as we sped back to the city.

“The Pitts house,” ordered Kennedy as we bowled along, after noting by his watch that it was after nine. Then to me he added, “We must see Mrs. Pitts once more, and alone.”

We waited some time after Kennedy sent up word that he would like to see Mrs. Pitts. At last she appeared. I thought she avoided Kennedy’s eye, and I am sure that her intuition told her that he had some revelation to make, against which she was steeling herself.

Craig greeted her as reassuringly as he could, but as she sat nervously before us, I could see that she was in reality pale, worn, and anxious.

“We have had a rather hard day,” began Kennedy after the usual polite inquiries about her own and her husband’s health had been, I thought, a little prolonged by him.

“Indeed?” she asked. “Have you come any closer to the truth?”

Kennedy met her eyes, and she turned away.

“Yes, Mr. Jameson and I have put in the better part of the day in going from one institution for the insane to another.”

He paused. The startled look on her face told as plainly as words that his remark had struck home.

Without giving her a chance to reply, or to think of a verbal means of escape, Craig hurried on with an account of what we had done, saying nothing about the original letter which had started us on the search for Thornton, but leaving it to be inferred by her that he knew much more than he cared to tell.

“In short, Mrs. Pitts,” he concluded firmly, “I do not need to tell you that I already know much about the matter which you are concealing.”

The piling up of fact on fact, mystifying as it was to me who had as yet no inkling of what it was tending toward, proved too much for the woman who knew the truth, yet did not know how much Kennedy knew of it. Minna Pitts was pacing the floor wildly, all the assumed manner of the actress gone from her, yet with the native grace and feeling of the born actress playing unrestrained in her actions.

“You know only part of my story,” she cried, fixing him with her now tearless eyes. “It is only a question of time when you will worm it all out by your uncanny, occult methods. Mr. Kennedy, I cast myself on you.”

THE TOXIN OF DEATH

The note of appeal in her tone was powerful, but I could not so readily shake off my first suspicions of the woman. Whether or not she convinced Kennedy, he did not show.

“I was only a young girl when I met Mr. Thornton,” she raced on. “I was not yet eighteen when we were married. Too late, I found out the curse of his life—and of mine. He was a drug fiend. From the very first life with him was insupportable. I stood it as long as I could, but when he beat me because he had no money to buy drugs, I left him. I gave myself up to my career on the stage. Later I heard that he was dead—a suicide. I worked, day and night, slaved, and rose in the profession—until, at last, I met Mr. Pitts.”

She paused, and it was evident that it was with a struggle that she could talk so.

“Three months after I was married to him, Thornton suddenly reappeared, from the dead it seemed to me. He did not want me back. No, indeed. All he wanted was money. I gave him money, my own money, for I made a great deal in my stage days. But his demands increased. To silence him I have paid him thousands. He squandered them faster than ever. And finally, when it became unbearable, I appealed to a friend. That friend has now succeeded in placing this man quietly in a sanitarium for the insane.”

“And the murder of the chef?” shot out Kennedy.

She looked from one to the other of us in alarm. “Before God, I know no more of that than does Mr. Pitts.”

Was she telling the truth? Would she stop at anything to avoid the scandal and disgrace of the charge of bigamy? Was there not something still that she was concealing? She took refuge in the last resort—tears.

Encouraging as it was to have made such progress, it did not seem to me that we were much nearer, after all, to the solution of the mystery. Kennedy, as usual, had nothing to say until he was absolutely sure of his ground. He spent the greater part of the next day hard at work over the minute investigations of his laboratory, leaving me to arrange the details of a meeting he planned for that night.

There were present Mr. and Mrs. Pitts, the former in charge of Dr. Lord. The valet, Edward, was also there, and in a neighbouring room was Thornton in charge of two nurses from the sanitarium. Thornton was a sad wreck of a man now, whatever he might have been when his blackmail furnished him with an unlimited supply of his favourite drugs.

“Let us go back to the very start of the case,” began Kennedy when we had all assembled, “the murder of the chef, Sam.”

It seemed that the mere sound of his voice electrified his little audience. I fancied a shudder passed over the slight form of Mrs. Pitts, as she must have realised that this was the point where Kennedy had left off, in his questioning her the night before.

“There is,” he went on slowly, “a blood test so delicate that one might almost say that he could identify a criminal by his very blood-crystals—the fingerprints, so to speak, of his blood. It was by means of these ‘hemoglobin clues,’ if I may call them so, that I was able to get on the right trail. For the fact is that a man’s blood is not like that of any other living creature. Blood of different men, of men and women differ. I believe that in time we shall be able to refine this test to tell the exact individual, too.

“What is this principle? It is that the hemoglobin or red colouring-matter of the blood forms crystals. That has long been known, but working on this fact Dr. Reichert and Professor Brown of the University of Pennsylvania have made some wonderful discoveries.

“We could distinguish human from animal blood before, it is true. But the discovery of these two scientists takes us much further. By means of blood-crystals we can distinguish the blood of man from that of the animals and in addition that of white men from that of negroes and other races. It is often the only way of differentiating between various kinds of blood.

“The variations in crystals in the blood are in part of form and in part of molecular structure, the latter being discovered only by means of the polarising microscope. A blood-crystal is only one two-thousand-two-hundred-and-fiftieth of an inch in length and one nine-thousandth of an inch in breadth. And yet minute as these crystals are, this discovery is of immense medico-legal importance. Crime may now be traced by blood-crystals.”

He displayed on his table a number of enlarged micro-photographs. Some were labelled, “Characteristic crystals of white man’s blood”; others “Crystallisation of negro blood”; still others, “Blood-crystals of the cat.”

“I have here,” he resumed, after we had all examined the photographs and had seen that there was indeed a vast amount of difference, “three characteristic kinds of crystals, all of which I found in the various spots in the kitchen of Mr. Pitts. There were three kinds of blood, by the infallible Reichert test.”

I had been prepared for his discovery of two kinds, but three heightened the mystery still more.

“There was only a very little of the blood which was that of the poor, faithful, unfortunate Sam, the negro chef,” Kennedy went on. “A little more, found far from his body, is that of a white person. But most of it is not human blood at all. It was the blood of a cat.”

The revelation was startling. Before any of us could ask, he hastened to explain.

“It was placed there by some one who wished to exaggerate the struggle in order to divert suspicion. That person had indeed been wounded slightly, but wished it to appear that the wounds were very serious. The fact of the matter is that the carving-knife is spotted deeply with blood, but it is not human blood. It is the blood of a cat. A few years ago even a scientific detective would have concluded that a fierce hand-to-hand struggle had been waged and that the murderer was, perhaps, fatally wounded. Now, another conclusion stands, proved infallibly by this Reichert test. The murderer was wounded, but not badly. That person even went out of the room and returned later, probably with a can of animal blood, sprinkled it about to give the appearance of a struggle, perhaps thought of preparing in this way a plea of self-defence. If that latter was the case, this Reichert test completely destroys it, clever though it was.” No one spoke, but the same thought was openly in all our minds. Who was this wounded criminal?

I asked myself the usual query of the lawyers and the detectives—Who would benefit most by the death of Pitts? There was but one answer, apparently, to that. It was Minna Pitts. Yet it was difficult for me to believe that a woman of her ordinary gentleness could be here to-night, faced even by so great exposure, yet be so solicitous for him as she had been and then at the same time be plotting against him. I gave it up, determining to let Kennedy unravel it in his own way.

Craig evidently had the same thought in his mind, however, for he continued: “Was it a woman who killed the chef? No, for the third specimen of blood, that of the white person, was the blood of a man; not of a woman.”

Pitts had been following closely, his unnatural eyes now gleaming. “You said he was wounded, you remember,” he interrupted, as if casting about in his mind to recall some one who bore a recent wound. “Perhaps it was not a bad wound, but it was a wound nevertheless, and some one must have seen it, must know about it. It is not three days.”

Kennedy shook his head. It was a point that had bothered him a great deal.

“As to the wounds,” he added in a measured tone “although this occurred scarcely three days ago, there is no person even remotely suspected of the crime who can be said to bear on his hands or face others than old scars of wounds.”

He paused. Then he shot out in quick staccato, “Did you ever hear of Dr. Carrel’s most recent discovery of accelerating the healing of wounds so that those which under ordinary circumstances might take ten days to heal might be healed in twenty-four hours?”

Rapidly, now, he sketched the theory. “If the factors that bring about the multiplication of cells and the growth of tissues were discovered, Dr. Carrel said to himself, it would perhaps become possible to hasten artificially the process of repair of the body. Aseptic wounds could probably be made to cicatrise more rapidly. If the rate of reparation of tissue were hastened only ten times, a skin wound would heal in less than twenty-four hours and a fracture of the leg in four or five days.

“For five years Dr. Carrel has been studying the subject, applying various extracts to wounded tissues. All of them increased the growth of connective tissue, but the degree of acceleration varied greatly. In some cases it was as high, as forty times the normal. Dr. Carrel’s dream of ten times the normal was exceeded by himself.”

Astounded as we were by this revelation, Kennedy did not seem to consider it as important as one that he was now hastening to show us. He took a few cubic centimetres of some culture which he had been preparing, placed it in a tube, and poured in eight or ten drops of sulphuric acid. He shook it.

“I have here a culture from some of the food that I found was being or had been prepared for Mr. Pitts. It was in the icebox.”

Then he took another tube. “This,” he remarked, “is a one-to-one-thousand solution of sodium nitrite.”
