He determined, however, if he could find a little time, to learn a little more of Léon Bouvier--perhaps to put a man to watch at the Café des Bons Camarades. That the keeper of this place in Soho should go regularly to Hatton Garden, the diamond market, was curious, and Dorrington had met and analysed too many extraordinary romances to put aside unexamined Jacques Bouvier's seemingly improbable story. But, having heard all the man had to say, it had clearly been his policy to get rid of him in the way he had done. Dorrington was quite ready to steal a diamond, or anything else of value, if it could be done quite safely, but he was no such fool as to give three-quarters of his plunder--or any of it--to somebody else. So that the politic plan was to send Jacques Bouvier away with the impression that his story was altogether pooh-poohed and was to be forgotten. II Dorrington left his office late that day, and the evening being clear, though dark, he walked toward Conduit Street by way of Soho; he thought to take a glance at the Café des Bons Camarades on his way, without being observed, should Jacques Bouvier be in the vicinity. Beck Street, Soho, was a short and narrow street lying east and west, and joining two of the larger streets that stretch north and south across the district. It was even a trifle dirtier than these by-streets in that quarter are wont to be. The Café des Bons Camarades was a little green-painted shop the window whereof was backed by muslin curtains, while upon the window itself appeared in florid painted letters the words "Cuisine Française." It was the only shop in the street, with the exception of a small coal and firewood shed at one end, the other buildings consisting of the side wall of a factory, now closed for the night, and a few tenement houses. An alley entrance--apparently the gate of a stable-yard--stood next the café. As Dorrington walked by the steamy window, he was startled to hear his own name and some part of his office address spoken in excited tones somewhere in this dark alley entrance; and suddenly a man rather well dressed, and cramming a damaged tall hat on his head as he went, darted from the entrance and ran in the direction from which Dorrington had come. A stoutly built Frenchwoman, carrying on her face every indication of extreme excitement, watched him from the gateway, and Dorrington made no doubt that it was in her voice that he had heard his name mentioned. He walked briskly to the end of the short street, turned at the end, and hurried round the block of houses, in hope to catch another sight of the man. Presently he saw him, running, in Old Compton Street, and making in the direction of Charing Cross Road. Dorrington mended his pace, and followed. The man emerged where Shaftesbury Avenue meets Charing Cross Road, and, as he crossed, hesitated once or twice, as though he thought of hailing a cab, but decided rather to trust his own legs. He hastened through the byways to St.
