but detection. I wager with you against that. Come, what do you say; shall it be a thousand dollars? I want a little excitement!"
"Well, you shall have it. At least you shall have the excitement of paying the thousand dollars to me; for though I think you are not really intending to become a criminal, in either event I may as well profit by your offer."
"What do you mean by 'in either event'?"
"Why, if you do not commit a crime you pay; and if you do, I am sure that you would be caught. Then, however much I should regret your disgrace, I warn you that I should cut you dead, and take your money."
"Then you accept the wager?"
"I do!"
"Done. Now for the conditions. I am to have one month in which to plan and commit my crime, and one year for avoiding the detectives. That is, if I am free at the end of one year, and can prove to you that I committed a crime within the stipulated period, I win the wager. If I am in jail awaiting trial, the bet cannot be settled until the law has had its way, and I am either proven innocent or guilty. Is that satisfactory?"
"Perfectly. But what class of crime will you commit?"
"My friend you are inquisitive. The wager is on, and my boasted caution must begin. Therefore, I must not tell you anything of the nature of my intended crime!"
"Why, do you suppose for an instant that I would betray you?"
"Well, yes, that idea does occur to me. Listen. As I said before, the necessities of the criminal prove his Nemesis. The necessities involve the object of the crime. That is always a good starting-point in following up a mysterious case. The more unusual the object the better, since it will fit fewer people. Plunder is the commonest and therefore the least promising to trace from. Revenge is common also, but better, because the special revenge connected with the deed must lead to the special individual most likely to execute such revenge. In this instance, I mean my own case, the object of the crime is so unique, that the detective who discovers it should be able to convict me. A crime committed to decide a wager is perhaps new."
"Its very novelty is your best safeguard."
"Yet there are two ways by which it may be discovered, and that is two too many. Had I undertaken this affair secretly there would really have been but a single way for one to learn my secret, – my own confession. As men have been weak enough to do this before now, I should even in that instance have taken precautions. But with my secret in the possession of a second party, the position is more complex."
"I assure you on my honor that I will not betray you. I will agree to forfeit five times the wager in such an event."
"I prefer that you should be perfectly at liberty in the matter. I expect it to be thus: in your own mind at present you do not think that I shall carry out my purpose. Therefore, your friendship for me is undisturbed. Then you count that, if I do commit a crime, it will be some trivial one that you may bring your conscience to excuse, under the circumstances. But let us suppose that a really great crime should be reported, and for some reason you should suspect me. You will hurry to my rooms before I get out of bed, and ask me flatly whether I am guilty. As flatly I should refuse to enlighten you. You would take this as a confession of guilt. You would perhaps argue that if your surmise were correct you would be an accessory before the fact, and to shield yourself and do your duty you would make a clean breast of it."
"I am beginning to be offended, Bob. I did not think you would trust me so little!"
"Don't get angry, old man. Remember that only a few minutes ago you warned me that you would cut me dead after the crime. We artistic criminals must be prepared against every contingency."
"I did not think when I spoke. I did not mean it."
"Yes, you did, and I am not at all angry. Let it be understood then that you will be at liberty to repeat the facts about this wager should your conscience prick you. It will be best for me to expect and be prepared for such action. But you have not asked what the second danger of discovery is. Can you guess?"
"Not unless you mean as you suggested, your own confession."
"No, though that really makes a third chance. Yet it is so simple. Have you noticed that we can hear a man snoring?"
"No!"
"Listen a moment! Do you not hear that? It is not exactly a snore, but rather a troubled breathing. Now that man is in the third section from us. Do you see the point?"
"I must confess that I would not make a detective."
"Why, my dear boy, if we can hear that fellow, why may not some one in the next compartment be listening to our tête-à-tête?" Mr. Barnes fairly glowed with admiration for the fellow's careful consideration of every point.
"Oh, I guess not. Everybody is asleep."
"The common criminal from necessity takes chances like that, without counting on them. I shall not. There is a possibility, however remote, that some one, in Number Ten say, has overheard us. Again he may even be a detective, and worse yet it might be your Mr. Barnes himself."
"Well, I must say if you prepare against such long odds as that you deserve to escape detection!"
"That is just what I will do. But the odds are not so great as you imagine. I read in an afternoon paper that Mr. Barnes had remained in Boston in connection with properly securing his prisoner during the day, but that he would leave for New York to-night. Of course the newspaper may have been wrong. Then in saying "to-night" it may have been inaccurate; but supposing that the statement were true, then there were three trains upon which he might have started, one at seven o'clock, one at eleven, and this one. One in three is not long odds."
"But even if he is on this train, there are ten coaches."
"Again you are wrong. After his hard work on this Pettingill case he would be sure to take a sleeper. Now if you recall the fact, I did not decide to go to New York to-night till the last minute. Then we found that we could not get a whole section, and were about to bunk together in a lower berth when, several more people applying, they determined to put on another coach. Therefore, unless Mr. Barnes secured his ticket during the day, he would inevitably have been assigned to this coach."
"Had you any special reason for suggesting Number Ten?"
"Yes. I know that Number Six is unoccupied. But just as we started some one came in, and I think took the upper berth of Number Ten."
"Mr. Barnes began to think that he would have exceedingly difficult work to detect this man in crime, were he really to commit one, in spite of the fact that he knew so much in advance. The conversation continued:
"Thus, you see, there are two ways by which my object may become known, a serious matter if unguarded against. As, however, I recognize the possibilities in advance, there will be no difficulty whatever, and the knowledge will be of no value to any detective, even though he be your Mr. Barnes."
"How will you avoid that danger?"
"My dear boy, do you suppose for an instant that I would reply to that, after pointing out that a detective may be listening? However, I will give you an idea. I will show you what I meant when I said that Pettingill had blundered. You said that he had lost only a button, and thought it clever in Barnes to trace him from the button. But a button may be a most important thing. If I should lose one of the buttons of my vest, whilst committing a crime, Mr. Barnes would trace me out in much less than ten days, and for this reason, they are the only ones of the kind in the world."
"How does that happen? I supposed that buttons were made by the thousand?"
"Not all buttons. For reasons which I need not tell the possibly listening detective, a friend travelling abroad had a set made especially, and brought them back to me as a present. They are six handsomely cut cameos, half the set having the profile head of Juliet, and the others a similar face of Romeo."
"A romance?"
"That is immaterial. Suppose that I should plan a robbery in order to decide this wager. As necessity would not urge me either as to time or place, I should choose my opportunity, let us say when but one person guarded the treasure. That one I should chloroform and also tie. Next,
