It was half-past seven o'clock, and the place was full of customers. Selwood took most of them to be foreigners. He also concluded after a first glance around him that the majority had some connection, more or less close, with either the dramatic, or the musical, or the artistic professions. There was much laughter and long hair, marvellous neckties and wondrous costumes; everybody seemed to be talking without regard to question or answer; the artillery of the voices mingled with the rattling of plates and popping of corks. Clearly this was no easy place in which to seek for a man whom one had never seen! Selwood allowed a waiter to conduct him to a vacant seat--a plush throne half-way along the restaurant. He ordered a modest dinner and a bottle of light wine, and following what seemed to be the custom, lighted a cigarette until his first course appeared. And while he waited he looked about him, noting everything that presented itself. Out of all the folk there, waiters and customers, the idle and the busy, he quickly decided that there was only one man who possessed particular interest for him. That man was the big, smiling, frock-coated, sleek-haired patron or proprietor, who strode up and down, beaming and nodding, sharp-eyed and courteous, and whom Selwood, from a glance at the emblazoned lettering of the bill-of-fare, took to rejoice in the name of Mr. Alessandro Bioni. This man, if he was landlord, or manager, of the Ravenna Hotel, was clearly the person to approach if one wanted information about the Luigi Dimambro who had given the place as his address as recently as November 12th. While he ate and drank, Selwood wondered how to go about his business. It seemed to him that the best thing to do, now that he had seen the place and assured himself that it was a hotel evidently doing a proper and legitimate business, was to approach its management with a plain question--was Mr. Luigi Dimambro staying there, or was he known there? Since Dimambro, whoever he might be, had given that as his address, something must be known of him. And when the smiling patron presently came round, and, seeing a new customer, asked politely if he was being served to his satisfaction, Selwood determined to settle matters at once. "The proprietor, I presume?" he asked. "Manager, sir," answered the other. "The proprietor, he is an old gentleman--practically retired." "Perhaps I can ask you a question," Selwood. "Have you got a Mr. Luigi Dimambro staying at your hotel? He is, I believe"--here Selwood made a bold shot at a possibility--"a seller of curios, or art objects. I know he stops here sometimes." The manager rubbed his hands together and reflected. "One moment, sir," he said. "I get the register. The hotel guests, they come in here for meals, but always I do not recollect their names, and sometimes not know them. But the register----"
