Unlike so many of my countrymen I am prepared to state that I detest the French capital. I always make my visits to it as brief as possible, then, my business completed, off I fly again, seeming to breathe more freely when I am outside its boundaries. I don’t know why this should be so, for I have always been treated with the utmost courtesy and consideration by its inhabitants, particularly by those members of the French Detective Force with whom I have been brought in contact.

On this visit I crossed with one of the cleverest Parisian detectives, a man with whom I have had many dealings. He was most anxious to ascertain the reason of my visit to his country. My assurance that I was not in search of any one of his own criminals seemed to afford him no sort of satisfaction. He probably regarded it as an attempt to put him off the scent, and I fancy he resented it. We reached Paris at seven o’clock, whereupon I invited him to dine with me at eight o’clock, at a restaurant we had both patronized on many previous occasions. He accepted my invitation, and promised to meet me at the time and place I named. On the platform awaiting our arrival was my man Dickson, to whom I had telegraphed, ordering him to meet me.

“Well, Dickson,” I said, when I had bade the detective an revoir, “what about our man?”

“I’ve had him under my eye, sir,” he answered. “I know exactly what he’s been doing, and where he’s staying.”

“That’s good news indeed,” I replied. “Have you discovered anything else about him?”

“Yes, sir,” he returned. “I find that he’s struck up a sudden acquaintance with a lady named Mademoiselle Beaumarais, and that they are to dine together at the Cafe des Ambassadeurs to-night. They have been in and out of half the jewellers’ shops in the Rue de la Paix to-day, and he’s spending a mint of money on her.”

“They are dining at the Cafe des Ambassadeurs to-night, did you say? At what time?”

“I cannot tell you that, sir,” Dickson replied. “I only know that they are to dine there together to-night.”

“And pray how did you find that out?”

“I made inquiries as to who she was, where she lived, and then pumped her maid,” he answered.

“You did not do anything that would excite his suspicions, I hope,” I put in. “You ought to know by this time what women are.”

“Oh, no, sir, you needn’t be afraid,” he said. “I was too careful for that. The maid and I are on very friendly terms. She believes me to be a Russian, and I’ve not denied it.”

“It would be safest not to do so,” I replied. “If she discovers that you are an Englishman, she might chance to mention the fact to her mistress. She would doubtless let it fall in conversation with him, and then all our trouble would be useless. You speak Russian, do you not?”

“Only pretty well, sir,” he answered. “I should be soon bowled out if I came in contact with a real one.”

“Well, I think I will be somewhere near the Cafe des Ambassadeurs to-night just to make sure of my man. After that I’ll tell you what to do next.”

“Very good, sir,” he returned. “I suppose you will be staying at the same place?”

“Yes, the same place,” I replied. “If you have anything to communicate, you can either call, or send word to me there.”

I thereupon departed for the quiet house at which I usually take up my abode when in Paris. The big hotels are places I steer clear of, for the simple reason that I often have business in connection with them, and it does not pay me to become too well known. At this little house I can go out and come in just as I please, have my meals at any time of the day or night, and am as well cared for as at my own abode in London. On this occasion the old lady of the house greeted me with flattering enthusiasm. She had received my telegram, she said, and my usual room awaited me. I accordingly ascended to it in order to dress myself for the dinner of the evening, and as I did so, thought of the pretty bedroom I had seen on the previous day, which naturally led me to think of the owner of the house, at that moment my employer. In my mind’s eye I could see her just as she had stood on that old stone bridge at Bishopstowe, with the sunset behind her and the church bells sounding across the meadows, calling the villagers to evensong. How much better it was, I argued, to be standing talking to her there in that old world peace, than to be dressing for a dinner at an up-to-date French restaurant. My toilet completed, I descended to the street, hired a fiacre, and drove to the restaurant where I had arranged to meet my friend. The place in question is neither an expensive nor a fashionable one. It has no halls of mirrors, no dainty little cabinets, but, to my thinking, you can obtain the best dinner in all Paris there. On reaching it I found my guest had been the first to arrive. We accordingly ascended the stairs to the room above, where we selected our table and sat down. My companion was a witty little man with half the languages of Europe on his tongue, and a knowledge of all the tricks and dodges of all the criminal fraternity at his finger-ends. He has since written a book on his experiences, and a stranger volume, or one more replete with a knowledge of the darker side of human nature it would be difficult to find. He had commenced his professional career as a doctor, and like myself had gradually drifted into the detective profession. Among other things he was an inimitable hand at disguising himself, as many a wretched criminal now knows to his cost. Even I, who know him so well, have been taken in by him. I have given alms to a blind beggar in the streets, have encountered him as a chiffonier prowling about the gutters, have sat next to him on an omnibus when he has been clothed as an artisan in a blue blouse, and on not one of those occasions have I ever recognized him until he made himself known to me. Among other things he was a decided epicure, and loved a good dinner as well as any of his compatriots. Could you but see him with his napkin tucked under his chin, his little twinkling eyes sparkling with mirth, and his face wreathed in smiles, you would declare him to be one of the jolliest-looking individuals you have ever encountered. See him, however, when he is on business and has a knotty problem to solve, and you will find a different man. The mouth has become one of iron, the eyes are as fierce as fierce can be. Some one, I remember, likened him to the great Napoleon, and the description is an exceedingly apt one.

“By the way,” I said, as we took a peep into our second bottle of Perrier-Jouet, “there is a question I want to put to you. Do you happen to be acquainted with a certain Mademoiselle Beaumarais?”

“I have known her for more years than she or I would care to remember,” he answered. “For a woman who has led the life she has, she wears uncommonly well. A beautiful creature! The very finest shoulders in all Paris, and that is saying something.”

He blew a kiss off the tips of his fingers, and raised his glass in her honour.

“I drink to her in this noble wine, but I do not let her touch my money. Oh no, la belle Louise is a clever woman, a very clever woman, but money trickles through her fingers like water through a sieve. Let me think for a moment. She ruined the Marquis D’Esmai, the Vicomte Cotforet, Monsieur D’Armier, and many others whose names I cannot now recall. The first is with our noble troops in Cochin China, the second is in Algeria, and the third I know not where, and now I have learnt since my arrival in Paris that she has got hold of a young Englishman, who is vastly wealthy. She will have all he has got very soon, and then he will begin the world anew. You are interested in that Englishman, of course?”

“How do you know that?”

“Because you question me about Mademoiselle Beaumarais,” he answered. “A good many people have asked me about her at different times, but it is always the man they want to get hold of. You, my astute Fairfax, are interested in the man, not because you want to save him from her, but because he has done a little something which he should not have done elsewhere. The money he is lavishing on Mademoiselle Louise, whence does it come? Should I be very wrong if I suggested gems?”

I gave a start of surprise. How on earth did he guess this?

“Yes! I see I’m right,” he answered with a little laugh. “Well, I knew it a long time ago. Ah, you are astonished! You should surely never allow yourself to be surprised by anything. Now I will tell you how I come to know about the gems. Some time ago a certain well-known lady of this city lost her jewel-case in a mysterious manner. The affair was placed in my hands, and when I had exhausted Paris, I went to Amsterdam, en route if necessary for London. You know our old friends, Levenstein and Schartzer?”

I nodded. I had had dealings with that firm on many occasions.

“Well, as I went into their office, I saw the gentleman who has been paying his attentions to the lady we have been discussing, come out. I have an excellent memory for faces, and when I saw him to-night entering the Cafe des Ambassadeurs, I recognized him immediately. Thus the mystery is explained.”

He shrugged his shoulders and spread his hands apart, like a conjurer who has just vanished a rabbit or an orange.

“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 Cafe des Ambassadeurs was progressing.

“They will proceed to a theatre afterwards, you may be sure,” my companion said. “In that case, if you like we could catch a glimpse of them as they come out. What do you say?”

I answered that I had not the least objection.

“One night does not make much difference. To-morrow morning I shall make a point of meeting him face to face.”

“Should you require my assistance then, I shall be most pleased to give it to you?” my companion replied.

I thanked him for his offer, and then we left the restaurant together, hailed a cab, and drove to his flat. It consisted of four rooms situated at the top of a lofty block of buildings near the river. From his windows he could look out over Paris, and he was wont to declare that the view he received in exchange was the most beautiful in the world. Fine as it was, I was scarcely so enthusiastic in my praise.

Among other things they were remarkable for the simplicity of their furniture, and also for the fact that in the sitting-room there was nothing to reveal the occupation of their owner. His clever old servant, Susanne, of whom ’twas said she would, did she but choose, make as clever a detective as her master (she had served him for more than forty years), brought us coffee so quickly that it would almost seem as if she had been aware that we should reach the house at that particular moment.

“We have plenty of time to spare,” said my host. “In the meantime it will be necessary for us to find out what they are doing. If you will wait I will despatch a messenger, who will procure us the information.”

He wrote something on a half-sheet of note-paper, rang the bell, and handed it to Susanne.

“Give that to Leon,” he said, “and tell him to be off with it at once.”

The woman disappeared, and when she had gone we resumed our conversation. Had he not had the good fortune to be such a great success in his own profession, what an admirable actor the man would have made! His power of facial contortion was extraordinary, and I believe that on demand he could have imitated almost any face that struck his fancy.

“And now with regard to our little excursion,” he said. “What would you like to be? As you are aware, I can offer you a varied selection. Will you be a workman, a pedlar, an elderly gentleman from the Provinces, or a street beggar?”

“I think the elderly gentleman from the Provinces would suit me best,” I answered, “while it will not necessitate a change of dress.”

“Very good then, so it shall be,” he replied. “We’ll be a couple of elderly gentlemen in Paris for the first time. Let me conduct you to my dressing-room, where you will find all that is necessary for your make-up.”

He thereupon showed me to a room leading out of that in which we had hitherto been sitting. It was very small, and lighted by means of a skylight. Indeed, it was that very skylight, so he always declared, that induced him to take the flat.

“If this room looked out over the back, or front, it would have been necessary for me either to have curtains, which I abominate, or to run the risk of being observed, which would have been far worse,” he had remarked to me once. “Needless to say there are times when I find it most necessary that my preparations should not be suspected.”

Taken altogether, it was a room that had a strange fascination for me. I had been in it many times before, but was always able to discover something new in it. It was a conglomeration of cupboards and shelves. A large variety of costumes hung upon the pegs in the walls, ranging from soldier’s uniforms to beggar’s rags. There were wigs of all sorts and descriptions on blocks, pads of every possible order and for every part of the body, humps for hunchbacks, wooden legs, boots ranging from the patent leather of the dandy to the toeless foot-covering of the beggar. There were hats in abundance, from the spotless silk to the most miserable head coverings, some of which looked as if they had been picked up from the rubbish-heap. There were pedlars’ trays fitted with all and every sort of ware, a faro-table, a placard setting forth the fact that the renowned Professor Somebody or Other was a most remarkable phrenologist and worthy of a visit. In fact there was no saying what there was not there. Everything that was calculated to be useful to him in his profession was to be found in the room.

For my own part I am not fond of disguises. Indeed on only two or three occasions, during the whole course of my professional career, have I found it necessary to conceal my identity. But to this wily little Frenchman disguise was, as often as not, a common occurrence.

Half-an-hour later, two respectable elderly gentlemen, looking more like professors from some eminent Lycee than detectives, left the house and proceeded in the direction of the Folly Theatre. The performance was almost at an end when we reached it, and we mingled with the crowd who had assembled to watch the audience come out. The inquiries we had made proved to be correct, and it was not very long before I saw the man I wanted emerge, accompanied by a female, who could be no other than Mademoiselle Beaumarais. Hayle was in immaculate evening dress, and as I could not but admit, presented a handsome figure to the world. A neat little brougham drew up beside the pavement in its turn, and into this they stepped. Then the door was closed upon them, and the carriage drove away.

“That’s my man,” I said to my companion, as we watched it pass out of sight. “To-morrow morning I shall pay him a little visit. I think you were quite right in what you said about the money. That woman must have made a fairly big hole in it already.”

“You may be quite sure of that,” he answered. “When she has finished with him there will not be much left for anybody else.”

“And now to get these things off and then home to bed. To-morrow will in all probability prove an exciting day.”

I accompanied him to his room and removed the disguise which had enabled me to see Hayle without his being aware of my identity, and then, bidding my friend good-night, returned to my abode. Before I went to bed, however, I sat down and wrote a report of my doings for Miss Kitwater. Little as I had to tell, the writing of this letter gave me considerable pleasure. I could imagine it coming like a breath from another world to that quiet house at Bishopstowe. I pictured the girl’s face as she read it, and the strained attention of the two men, who, needless to say, would hang on every word. When I had finished it I went to bed, to dream that Gideon Hayle and I were swimming a race in the Seine for five gigantic rubies which were to be presented to the winner by Miss Kitwater.

Next morning I arose early, went for a stroll along the Boulevards, and returned to breakfast at eight o’clock. In the matter of my breakfasts in Paris, I am essentially English. I must begin the day with a good meal, or I am fit for nothing. On this particular occasion I sat down on the best of terms with myself and the world in general. I made an excellent meal, did the best I could with the morning paper, for my French is certainly not above reproach, and then wondered when I should set out to interview the man whose flight from England had proved the reason of my visiting Paris. Then the door opened and the concierge entered with the words, “A gentleman to see Monsieur!” Next moment to my overwhelming surprise no less a person than Gideon Hayle entered the room.
