Chapter 6

"I don't like her," returned Inez, with a frown. "My father knew her--too well. She is a schemer, an adventuress. Once she has a hold on a man, one cannot say--" She paused, then went on in a different tone. "But I would rather not talk about the woman. I am afraid of her. Never does she talk to me that she does not get something out of me that I do not wish to tell her. She is uncanny."

Personally, I could not blame Inez for her opinion. I could understand it. Those often baleful eyes had a penetrating power that one might easily fall a victim to.

"But you can trust Mr. Lockwood," he returned. "Surely he is proof against her, against any woman."

Inez flushed. It was evident that of all the men who were interested in the little beauty, Lockwood was first in her mind. Yet when Kennedy put the question thus she hesitated. "Yes," she replied, "of course, I trust him. It is not that woman whom I fear with him."

She said it with an air almost of defiance. There was some kind of struggle going on in her mind, and she was too proud to let us into the secret.

Kennedy rose and bowed. For the present he had come to the conclusion that if she would not let us help her openly the only thing to do was to help her blindly.

Half an hour later we were at Norton's apartment, not far from the University campus. He listened intently as Kennedy told such parts of what we had done as he chose. At the mention of the arrow poison, he seemed startled beyond measure.

"You are sure of it?" he asked anxiously.

"Positive, now," reiterated Kennedy.

Norton's face was drawn in deep lines. "If some one has the secret," he cried hastily, "who knows when and on whom next he may employ it?"

Coming from him so soon after the same idea had been hinted at by the coroner, I could not but be impressed by it.

"The very novelty of the thing is our best protection," asserted Kennedy confidently. "Once having discovered it, if Walter gives the thing its proper value in the Star, I think the criminal will be unlikely to try it again. If you had had as much experience in crime as I have had, you would see that it is not necessarily the unusual that is baffling. That may be the surest way to trace it. Often it is because a thing is so natural that it may be attributed to any person among several, equally well."

Norton eyed us keenly, and shook his head. "You may be right," he said doubtfully. "Only I had rather that this person, whoever he may be, had fewer weapons."

"Speaking of weapons," broke in Kennedy, "you have had no further idea of why the dagger might have been taken?"

"There seems to have been so much about it that I did not know," he returned, "that I am almost afraid to have an opinion. I knew that its three-sided sheath inclosed a sharp blade, yet who would have dreamed that that blade was poisoned?"

"You are lucky not to have scratched yourself with it by accident while you were studying it."

"Possibly I might have done it, if I had had it in my possession longer. It was only lately that I had leisure to study it."

"You knew that it might offer some clue to the hidden treasure of Truxillo?" suggested Kennedy. "Have you any recollection of what the inscriptions on it said?"

"Yes," returned Norton, "I had heard the rumours about it. But Peru is a land of tales of buried treasure. No, I can't say that I paid much more attention to it than you might have done if some one asserted that he had another story of the treasure of Captain Kidd. I must confess that only when the thing was stolen did I begin to wonder whether, after all, there might not be something in it. Now it is too late to find out. From the moment when I found that it was missing from my collection I have heard no more about it than you have found out. It is all like a dream to me. I cannot believe even yet that a mere bit of archaeological and ethnological specimen could have played so important a part in the practical events of real life."

"It does seem impossible," agreed Kennedy. "But it is even more remarkable than that. It has disappeared without leaving a trace, after having played its part."

"If it had been a mere robbery," considered Norton, "one might look for its reappearance, I suppose, in the curio shops. For to-day thieves have a keen appreciation of the value of such objects. But, now that you have unearthed its use against Mendoza--and in such a terrible way--it is not likely that that will be what will happen to it. No, we must look elsewhere."

"I thought I would tell you," concluded Kennedy, rising to go. "Perhaps after you have considered it over night some idea may occur to you."

"Perhaps," said Norton doubtfully. "But I haven't your brilliant faculty of scientific analysis, Kennedy. No, I shall have to lean on you, in that, not you on me."

We left Norton, apparently now more at sea than ever. At the laboratory Kennedy plunged into some microphotographic work that the case had suggested to him, while I dashed off, under his supervision, an account of the discovery of curare, and telephoned it down to the Star in time to catch the first morning edition, in the hope that it might have some effect in apprising the criminal that we were hard on his trail, which he had considered covered.

I scanned the other papers eagerly in the morning for Kennedy, hoping to glean at least some hints that others who were working on the case might have gathered. But there was nothing, and, after a hasty bite of breakfast, we hurried back to take up the thread of the investigation where we had laid it down.

To our surprise, on the steps of the Chemistry Building, as we approached, we saw Inez Mendoza already waiting for us in a high state of agitation. Her face was pale, and her voice trembled as she greeted us.

"Such a dreadful thing has come to me," she cried, even before Kennedy could ask her what the trouble was.

From her handbag she drew out a crumpled, dirty piece of paper in an envelope.

"It came in the first mail," she explained. "I could not wait to send it to you. I brought it myself. What can it mean?"

Kennedy unfolded the paper. Printed in large characters, in every way similar to the four warnings that had been sent to us, was just one ominous line. We read:

"Beware the man who professes to be a friend of your father."

I glanced from the note to Kennedy, then to Inez. One name was in my mind, and before I knew it I had spoken it.

"Lockwood?" I queried inadvertently.

Her eyes met mine in sharp defiance. "Impossible," she exclaimed. "It is some one trying to injure him with me. Beware of Mr. Lockwood? How absurd!"

Yet it must have meant Lockwood. No one else could have been meant. It was he, most of all, who might be called a friend of her father. She seemed to see the implication without a word from us.

I could not help sympathizing with the brave girl in her struggle between the attack against Lockwood and her love and confidence in him. It did not need words to tell me that evidence must be overwhelming to convince her that her lover might be involved in any manner.

IX

THE PAPER FIBRES

Kennedy examined the anonymous letter carefully for several minutes, while we watched him in silence.

"Too clever to use a typewriter," he remarked, still regarding the note through the lens of a hand-glass. "Almost any one would have used a machine. That would have been due to the erroneous idea that typewriting cannot be detected. The fact is that the typewriter is perhaps a worse means of concealing identity than is disguised handwriting, especially printing like this. It doesn't afford the effective protection to the criminal that one supposes. On the contrary, the typewriting of such a note may be the direct means by which it can be traced to its source. We can determine what kind of machine it was done with, then what particular machine was used can be identified."

He paused and indicated a number of little instruments which he had taken from a drawer and laid on the table, as he tore off a bit of the corner of the sheet of paper and examined it.

"There is one thing I can do now, though," he continued. "I can study the quality of the paper in this sheet. If it were only torn like those warnings we have already received, it might perhaps be mated with another piece as accurately as if the act had been performed before our eyes."

He picked up a little instrument with a small curved arm and a finely threaded screw that brought the two flat surfaces of the arm and the end of the screw together.

"There is no such good fortune in this case, however," he resumed, placing the paper between the two small arms. "But by measurements made by this vernier micrometer caliper I can find the precise thickness of the paper as compared to the other samples."

He turned to a microscope and placed the corner of the paper under it. Then he drew from the drawer the four scraps of paper which had already been sent to us, as well as a pile of photographs.

"Under ordinary circumstances," he explained, "I should think that what I am doing would be utterly valueless as a clue to anything. But we are reduced to the minutiae in this affair. And to-day science is not ready to let anything pass as valueless."

He continued to look at the various pieces of paper under the microscope. "I find under microscopic examination," he went on, addressing Inez, but not looking up from the eye-piece as he shifted the papers, "that the note you have received, Senorita Mendoza, is written on a rather uncommon linen bond paper. Later I shall take a number of microphotographs of it. I have here, also, about a hundred microphotographs of the fibres in other kinds of paper, many of them bonds. These I have accumulated from time to time in my study of the subject. None of them, as you can see, shows fibres resembling this one in question, so that we may conclude that it is of uncommon quality.

"Here I have the fibres, also, of four pieces of paper that have already figured in the case. These four correspond, as well as the indentures of the torn edges. As for the fibres, lest you should question the accuracy of the method, I may say that I know of a case where a man in Germany was arrested, charged with stealing a government bond. He was not searched until later. There was no evidence, save that after the arrest a large number of spitballs were found around the courtyard under his cell window. This method of comparing the fibres of the regular government paper was used, and by it the man was convicted of stealing the bond. I think it is unnecessary to add that in the present case I can see definitely that not only the four pieces of paper that bore warnings to us were the same kind, but that this whole sheet, with its anonymous warning to you, is also the same."

Inez Mendoza looked at Kennedy as though he possessed some weird power. Her face, which had already been startled into an expression of fear at his mention of Lockwood, now was pale.

"Other warnings?" she repeated tremulously.

Quickly Kennedy explained what had already happened to us, watching the effect on her as he read of the curse of Mansiche and the Gold of the Gods.

"Oh," she cried, mastering her emotion with a heroic effort, "I wish my father had never become mixed up in the business. Ever since I was a little girl I have heard these vague stories of the big fish and the little fish, the treasure, and the curse. But I never thought they were anything but fairy tales. You remember, when I first saw you, I did not even tell them to you."

"Yes," returned Kennedy. "I remember. But had you no other reason? Did you, down in your heart, think them really fairy tales?"

She shuddered. "Perhaps not," she murmured. "But I have heard enough of you detectives to know that you do not think a woman's fears exactly evidence."

"Still they might lead to evidence," suggested Kennedy.

She looked at him, more startled than ever, for already he had given her a slight exhibition of his powers.

"Mr. Kennedy," she exclaimed, "I am positively afraid of you, afraid that every little thing I do may lead to something I don't intend."

There was a frankness about the remark that would have been flattering from a man, but from her excited sympathy.

"No," she went on, "I have nothing tangible--only my feelings. I fear I must admit that my father had enemies, though who they are I cannot tell you. No, it is all in my heart--not in my head. There are those whom I dislike--and there are those whom I like and trust. You may call me foolish, but I cannot help trusting--Mr. Lockwood."

She had not meant to say his name, and Kennedy and I looked at her in surprise.

"You see?" she continued. "Every time I talk I say something, convey some impression that is the opposite of what I wish. Oh--what shall I do? Have I no one to trust?"

She was crying.

"You may trust me, Senorita," said Kennedy, in a low tone, pausing before her. "At least I have no other interest than finding the truth and helping you. There--there. We have had enough to-day. I cannot ask you to try to forget what has happened. That would be impossible. But I can ask you, Senorita, to have faith--faith that it will all turn out better, if you will only trust me. When you feel stronger--then come to me. Tell me your fears--or not--whichever does you the most good. Only keep your mind from brooding. Face it all as you know your father would have you do."

Kennedy's words were soothing. He seemed to know that tears were the safety-valve she needed.

"Mr. Jameson will see that you get home safely in a taxicab," he continued. "You can trust him as you would myself."

I can imagine circumstances under which I would have enjoyed escorting Inez to her home, but today was not one of the times. Yet she seemed so helpless, so grateful for everything we did for her that I did not need even the pressure of her little hand as she hurried into the apartment from the car with a hasty word of thanks.

"You will tell Mr. Kennedy--you will both be--so careful?" she hesitated before leaving me.

I assured her that we would, wondering what she might fear for us, as I drove away again. There did not happen to be any of the newspaper men about at the time, and I did not stop.

Back in the laboratory, I found Kennedy arranging something under the rug at the door as I came up the hall.

"Don't step there, Walter," he cautioned. "Step over the rug. I'm expecting visitors. How was she when she arrived home?"

I told him of her parting injunction.

"Not bad advice," he remarked. "I think there's a surprise back of those warnings. They weren't sent just for effect."

He had closed the door, and we were standing by the table, looking at the letters, when we heard a noise at the door.

It was Norton again.

"I've been thinking of what you told me last night," he explained, before Kennedy had a chance to tell him to step over the rug. "Has anything else happened?"

Kennedy tossed over the anonymous letter, and Norton read it eagerly.

"Whom does it mean?" he asked, quickly glancing up, then adding, "It might mean any of us who are trying to help her."

"Exactly," returned Kennedy. "Or it might be Lockwood, or even de Moche. By the way, you know the young man pretty well, don't you? I wonder if you could find him anywhere about the University this morning and persuade him to visit me?"

"I will try," agreed Norton. "But these people are so very suspicious just now that I can't promise."

Norton went out a few minutes later to see what he could do to locate Alfonso, and Kennedy replaced another blank sheet of paper for that under the rug on which Norton had stepped before we could warn him.

No sooner had he gone than Kennedy reached for the telephone and called Whitney's office. Lockwood was there, as he had hoped, and, after a short talk, promised to drop in on us later in the morning.

It was fully half an hour before Norton returned, having finally found Alfonso. De Moche entered the laboratory with a suspicious glance about, as though he thought something might have been planted there for him.

"I had a most interesting talk with your mother yesterday," began Kennedy, endeavouring by frankness to put the young man at ease. "And this morning, already, Senorita Mendoza has called on me."

De Moche was all attention at the words. But before he could say anything Kennedy handed him the anonymous letter. He read it, and his face clouded as he handed it back.

"You have no idea who could have sent such a note?" queried Craig, "or to whom it might refer?"

He glanced at Norton, then at us. It was clear that some sort of suspicion had flashed over him. "No," he said quickly, "I know no one who could have sent it."

"But whom does it mean?" asked Kennedy, holding him to the part that he avoided.

The young man shrugged his shoulders. "She has many friends," he answered simply.

"Yes," persisted Kennedy, "but few against whom she might be warned in this way. You do not think it is Professor Norton, for instance--or myself?"

"Oh, no, no--hardly," he replied, then stopped, realizing that he had eliminated all but Lockwood, Whitney, and himself.

"It could not be Mr. Lockwood?" demanded Craig.

"Who sent it?" he asked, looking up.

"No--whom it warns against."

De Moche had known what Kennedy meant, but had preferred to postpone the answer. It was native never to come to the point unless he was forced to do so. He met our eyes squarely. He had not the penetrating power that his mother possessed, yet his was a sharp faculty of observation.

"Mr. Lockwood is very friendly with her," he admitted, then seemed to think something else necessary to round out the idea. "Mr. Kennedy, I might have told her the same myself. Senorita Mendoza has been a very dear friend--for a long time."

I had been so used to having him evasive that now I did not exactly know what to make of such a burst of confidence. It was susceptible of at least two interpretations. Was he implying that it was sent to cast suspicion on him, because he felt that way himself or because he himself was her friend?

"There have been other warnings," pursued Kennedy, "both to myself and Mr. Jameson, as well as Professor Norton and Dr. Leslie. Surely you must have some idea of the source."

De Moche shook his head. "None that I can think of," he replied. "Have you asked my mother?"

"Not yet," admitted Kennedy.

De Moche glanced at his watch. "I have a lecture at this hour," he remarked, evidently glad of an excuse to terminate the interview.

As he left, Kennedy accompanied him to the door, careful himself to step over the mat.

"Hello, what's new?" we heard a voice in the hall.

It was Lockwood, who had come up from downtown. Catching sight of de Moche, however, he stopped short. The two young men met face to face. Between them passed a glance of unconcealed hostility, then each nodded stiffly.

De Moche turned to Kennedy as he passed down the hall. "Perhaps it may have been sent to divert suspicion--who can tell?" he whispered.

Kennedy nodded appreciatively, noting the change.

At the sound of Lockwood's voice both Norton and I had taken a step further after them out into the hall, Norton somewhat in advance. As de Moche disappeared for his lecture, Kennedy turned to me from Lockwood and caught my eye. I read in his glance that fell from me to the mat that he wished me quietly to abstract the piece of paper which he had placed under it. I bent down and did so without Lockwood seeing me.

"Why was he here?" demanded Lockwood, with just a trace of defiance in his voice, as though he fancied the meeting had been framed.

"I have been showing this to every one who might help me," returned Kennedy, going back into the laboratory after giving me an opportunity to dispose of the shoe-prints.

He handed the anonymous letter and the other warnings to the young soldier of fortune, with a brief explanation.

"Why don't they come out into the open, whoever they are?" commented Lockwood, laying the papers down carelessly again on the table. "I'll meet them--if they mean me."

"Who?" asked Kennedy.

Lockwood faced Norton and ourselves.

"I'm not a mind reader," he said significantly. "But it doesn't take much to see that some one wants to throw a brick at me. When I have anything to say I say it openly. Inez Mendoza without friends just now would be a mark, wouldn't she?"

His strong face and powerful jaw were set in a menacing scowl. He would be a bold man who would have come between Lockwood and the lady under the circumstances.

"You are confident of Mr. Whitney?" inquired Kennedy.

"Ask Norton," replied Lockwood briefly. "He knew him long before I did."

Norton smiled quietly. "Mr. Kennedy should know what my opinion of Mr. Whitney is, I think," replied Norton confidently.

"I trust that you will succeed in running these blackmailers down," pursued Lockwood, still standing. "If I did not have more than I can attend to already since the murder of Mendoza I'd like to take a hand myself. It begins to look to me, after reading that letter, as though there was nothing too low for them to attempt. I shall keep this latest matter in mind. If either Mr. Whitney or myself get any hint, we'll turn it over to you."

Norton left shortly after Lockwood, and Kennedy again picked up the letter and scanned it. "I could learn something, I suppose, if I analyzed this printing," he considered, "but it is a tedious process. Let me see that envelope again. H-m, postmarked by the uptown sub-station, mailed late last night. Whoever sent it must have done so not very far from us here. Lockwood seemed to take it as though it applied to himself very readily, didn't he? Much more so than de Moche. Only for the fact that the fibres show it to be on paper similar to the first warnings, I might have been inclined to doubt whether this was bona fide. At least, the sender must realize now that it has produced no appreciable effect--if any was intended."

Kennedy's last remark set me thinking. Could some one have sent the letter not to produce the effect apparently intended, but with the ultimate object of diverting suspicion from himself? Lockwood, at least, had not seemed to take the letter very seriously.

THE X-RAY READER

"I think I'll pay another visit to Whitney, in spite of all that Norton and Lockwood say about him," remarked Kennedy, considering the next step he would take in his investigation.

Accordingly, half an hour later we entered his Wall Street office, where we were met by a clerk, who seemed to remember us.

"Mr. Whitney is out just at present," he said, "but if you will be seated I think I can reach him by telephone."

As we sat in the outer office while the clerk telephoned from Whitney's own room the door opened and the postman entered and laid some letters on a table near us. Kennedy could not help seeing the letter on top of the pile, and noticed that it bore a stamp from Peru. He picked it up and read the postmark, "Lima," and the date some weeks previous. In the lower corner, underscored, were the words "Personal--Urgent."

"I'd like to know what is in that," remarked Craig, turning it over and over.

He appeared to be considering something, for he rose suddenly, and with a nod of his head to himself, as though settling some qualm of conscience, shoved the letter into his pocket.

A moment later the clerk returned. "I've just had Mr. Whitney on the wire," he reported. "I don't think he'll be back at least for an hour."

"Is he at the Prince Edward Albert?" asked Craig.

"I don't know," returned the clerk, oblivious to the fact that we must have seen that in order to know the telephone number he must have known whether Mr. Whitney was there or elsewhere.

"I shall come in again," rejoined Kennedy, as we bowed ourselves out. Then to me he added, "If he is with Senora de Moche and they are at the Edward Albert, I think I can beat him back with this letter if we hurry."
