London by night had always had an immense fascination for me. Coming out of the restaurant after supper, I felt no inclination to return to my lodgings, and end the greatest night of my life tamely with a book and a pipe. Here was I, a young man, fortified by an excellent supper, in the heart of Stevenson’s London. Why should I have no New Arabian Night adventure? I would stroll about for half an hour, and give London a chance of living up to its reputation. I walked slowly along Piccadilly, and turned up Rupert Street. A magic name. Prince Florizel of Bohemia had ended his days there in his tobacconist’s divan. Mr. Gilbert’s Policeman Forth had been discovered there by the men of London at the end of his long wanderings through Soho. Probably, if the truth were known, Rudolf Rassendyl had spent part of his time there. It could not be that Rupert Street would send me empty away. My confidence was not abused. Turning into Rupert Court, a dark and suggestive passage some short distance up the street on the right, I found a curious little comedy being played. A door gave on to the deserted passageway, and on each side of it stood a man—the lurcher type of man that is bred of London streets. The door opened inwards. Another man stepped out. The hands of one of the lurchers flew to the newcomer’s mouth. The hands of the other lurcher flew to the newcomer’s pockets. At that moment I advanced. The lurchers vanished noiselessly and instantaneously. Their victim held out his hand. “Come in, won’t you?” he said, smiling sleepily at me. I followed him in, murmuring something about “caught in the act.” He repeated the phrase as we went upstairs. “‘Caught in the act.’ Yes, they are ingenious creatures. Let me introduce myself. My name is Julian Eversleigh. Sit down, won’t you? Excuse me for a moment.” He crossed to a writing-table. Julian Eversleigh inhabited a single room of irregular shape. It was small, and situated immediately under the roof. One side had a window which overlooked Rupert Court. The view from it was, however, restricted, because the window was inset, so that the walls projecting on either side prevented one seeing more than a yard or two of the court. The room contained a hammock, a large tin bath, propped up against the wall, a big wardrobe, a couple of bookcases, a deal writing-table—at which the proprietor was now sitting with a pen in his mouth, gazing at the ceiling—and a divan-like formation of rugs and cube sugar boxes. The owner of this mixed lot of furniture wore a very faded blue serge suit, the trousers baggy at the knees and the coat threadbare at the elbows. He had the odd expression which green eyes combined with red hair give a man. “Caught in the act,” he was murmuring. “Caught in the act.” The phrase seemed to fascinate him.
