"Has the man of whom we are speaking done very wrong?" he inquired.
"The stones he sold in London and Amsterdam belonged to himself and his two partners," I answered. "He has not given them their share of the transaction. That is all."
"They had better be quick about it then, or they are not likely to get anything. It would be a very big sum that would tempt la belle Louise to be faithful for a long period. If your employers really desire to punish him, and they are not in want of money, I should say do not let them interfere. She will then nibble-nibble at what he has got like a mouse into a store of good things. Then presently that store will be all gone, and then she will give him up, and he, the man, will go out and shoot himself, and she will pick up somebody else, and will begin to nibble-nibble just as before. As I say, there will be somebody else, and somebody else, right up to the end of the chapter. And with every one she will grow just an imperceptible bit older. By and by the wrinkles will appear; I fancy there are just one or two already. Then she will not be so fastidious about her hundred of thousand francs, and will condescend to think of mere thousands. After that it will come to simple hundreds. Then there will be an interval—after which a garret, a charcoal brazier, and the Morgue. I have known so many, and it is always the same. First, the diamonds, the champagne, the exquisite little dinners at the best restaurants, and at last the brazier, the closed doors and windows, and the cold stone slab. There is a moral in it, my dear friend, but we will not look for it to-night. When do you intend to commence business with your man?"
"At once," I answered. "He knows that I am after him and my only fear is that he will make a bolt. I cannot understand why he is dallying in Paris so long?"
"For the simple reason that he is confident he has put you off the scent," was my companion's reply. "He is doing the one foolish thing the criminal always does sooner or later; that is to say, he is becoming over-confident of his own powers to elude us. You and I, my friend, should be able to remember several such instances. Now, strange to say, I came across a curious one the other day. Would you care to hear it?"
He lit a cigarette and blew a cloud of smoke while he waited for my answer.
"Very much," I said, being well aware that his stories were always worth hearing.
"This is a somewhat remarkable case," he said. "I will mention no names, but doubtless you can read between the lines. There was a man who murdered his wife in order that he might marry another woman. The thought which he gave to it, and the clever manner in which he laid his plans, not only for the murder, but also for the disposal of the body, marked him as a criminal in the possession of a singularly brilliant intellect. He gave no hint to anybody, but left the country without leaving the faintest clue concerning his destination behind him. I was called in to take over the case, but after some consideration could make nothing of it. I have no objection to admitting that I was completely baffled. Now it so happened that I discovered that the man's mother was of Irish extraction. He, believing that he would be safe on that island, engaged a passage on board a steamer from Havre to Belfast. She was to pick up at Southampton, Plymouth, and Bristol, en route. My man, who, by the way, was a very presentable person, and could be distinctly sociable when he pleased, endeavoured to make himself agreeable to the passengers on board. On the first evening out of port, the conversation turned upon the value of diamonds, and one of the ladies on board produced some costly stones she happened to have in her possession. The murderer, who, you must understand, was quite safe, was unhappily eaten up with vanity. He could not forego the boast that he was the possessor of a magnificent ring, which had been given him by the ex-Emperor Napoleon III. Needless to say this information excited considerable interest, and he was asked to produce it for the general edification.
"He declared that it was too late to do so that evening, but said that he would do so on the morrow, or, at any rate, before he left the vessel. In the excitement of reaching Southampton the matter was for the moment forgotten, but on the day that they arrived in Plymouth one of the lady passengers reminded him of his promise. This was followed by another application. Thus surrounded, the unhappy man found himself in the unpleasant position of being discovered in the perpetration of an untruth, or of being compelled to invent some feasible tale in order to account for his not being able to produce the ring. It was at this juncture that he made his great mistake. Anxious, doubtless, to attract attention, he returned from his cabin with the astounding declaration that the lock had been forced, and the famous ring stolen from his trunk in which it had lain concealed. He certainly acted his part well, but he did not realize to what consequences it would lead. The matter was reported to the police, and a search was made through the vessel. The passengers were naturally indignant at such treatment, and for the rest of the voyage the man found himself taking, what you English 'call the cold shoulder.' He reached Belfast, made his way into the country, and presently settled down. Later on, when the pursuit had died down, it was his intention to ship for America, where he was to be joined by the woman, to obtain whom he had in the first place committed the crime. Now observe the result. Photographs of the missing man and the murdered woman were circulated all through France, while not a few were sent to England. One of these pictures reached Plymouth, where it was shown to the officer who had investigated the case on the boat on its way to Ireland. He immediately recognized the man who had made the charge against his fellow-passengers. After that it was easy to trace him to Belfast and his hiding-place on land. Extradition was, of course, granted, and he left the place. Had he not imagined that in his safety he could indulge his vanities, I confidently believe I should never have found him. When you come to think of it, it is hard to come to the guillotine for a diamond that never existed, is it not?"
I agreed with him, and then suggested that we should amuse ourselves by endeavouring to find out how the dinner at the Café des Ambassadeurs was progressing.
