But, looking round the crowded room, I can, from my own personal knowledge of facts, select half a dozen specimens of the mystery of the money spent. A tall, military-looking man leaves one of the tables as we enter and comes across and shakes hands with me. It would be rude of me to say "I don't know you" in a public room. He sees my hesitation and exclaims, "Ah! you don't remember me, I see. I am Sir ----------. I used to see you very often at the old Pelican Club." I make a conventional reply and pass to the other end of the room. My impression of Sir ---------- is not a favourable one. I remember having heard something about him, and I am a little uneasy at this public claiming of acquaintanceship. The Baronet is with a lady--a very charming lady, to judge by her appearance. I ask an _habitué_ of the café, who is a friend of mine, if he knows anything about Sir ----------. "I don't think much of him," is the reply. "He was here with that lady the day before yesterday, and he got up and shook hands with Colonel -------- just as he did with you. The Colonel told me afterwards he was sure he had never met the man before." Two weeks later the reason for this little comedy of acquaintanceship was made clear. The Baronet appeared at Bow Street police court and turned out to be no baronet at all, but an adventurer who had imposed his title upon confiding tradespeople and unsuspecting women. He had victimized half a dozen of the former and married two of the latter. And from both he had obtained a considerable amount of money. Sir -------- got his living by frequenting the haunts of well-known people, shaking hands with some of them, and so establishing himself in the confidence of his dupes, one or other of whom he was in the habit of inviting to lunch at the restaurant and to sit in the café with him afterwards. The "trick" is not a new one. A high police official whose features are well known once told me of a case in which he had been selected for the "old acquaintance" dodge. A gentleman in a restaurant came up to the official and shook him warmly by the hand. "Ah! my dear --------. How are you?" he said in a loud voice. "I hope Mrs. -------- is better." The official's wife _had_ been very ill, and the question at once disarmed him. He returned the hand-shake, imagining that the man really _was_ an acquaintance whose face he failed to recall. On the strength of that hand-shake the "acquaintance" succeeded in victimizing a gentleman who witnessed the interview to the extent of £500. A high police official would hardly shake hands in a public place with a swindler. But let us take another look round the café in which the sham Baronet claimed acquaintance with me. At a table in the far corner three smartly-dressed men are seated. They are smoking the most expensive cigars and drinking the oldest liqueur brandy in the establishment.
