"No," he decided, "I don't think that it would be Doctor Gant. Jocelyn Thew has finished with him all right. He did his job well and faithfully, but he was only a hired tool. Speculation, however, is useless. We must wait for Henshaw's news. Perhaps this third guest, whoever he may be, may give us a clue as to Jocelyn Thew's influence over Miss Beverley." The telephone rang a few minutes later. Crawshay this time took up the receiver, and Brightman the spare one which hung by the side. It was Henshaw speaking. "Miss Beverley has just gone in to dinner," he announced. "She is accompanied by Mr. Jocelyn Thew and a young officer in the uniform of a Flight Commander." "What is his name?" Crawshay asked. "I have had no opportunity of finding out yet," was the reply. "I believe that he is staying in the hotel, and he seems to be on very intimate terms with Miss Beverley." "On no account lose sight of the party," Crawshay directed, "and try and find out the young soldier's name. Wasn't he introduced to Jocelyn Thew?" "Not a bit of it," was the prompt reply. "They shook hands very much like old friends." "Go back and watch," Crawshay directed. "I must know his name. The sooner you can find out, the better. I want to get away within a few minutes, if I can." They left the instrument. Crawshay, who seemed a little nervous, took a cigarette from an open box which he passed across to his companion, and strolled up and down the room for a few moments with his hands in his pockets. "A young officer," he remarked, "presumably English, known to both Miss Beverley and Jocelyn Thew, seems rather a puzzle. He may be the connecting link. I hope to goodness your man won't be long, Brightman." "Are you in a hurry?" the detective asked. Crawshay nodded. "I want to get round to the Savoy," he announced. Brightman smiled slightly. "Were you thinking about the young lady, sir?" he asked. "I thought it might be useful to renew my acquaintance with her," Crawshay explained, a little laboriously. "I shouldn't think she'd go out alone." "She has probably made some friends by this time," Brightman observed. Crawshay dropped his eyeglass and polished it. "From my experience of the young lady," he said, a little stiffly, "I should think it improbable. I happened to meet her twice in New York, and she struck me as being an extraordinarily well-behaved and, in her natural way, very attractive person." "Do you suppose that she came to Europe after Jocelyn Thew?" Brightman asked. "Oh, damn Jocelyn Thew!" Crawshay replied. "I should think it most unlikely. You and I have both seen the man's _dossier_. Most cold-blooded person alive." The telephone broke in once more upon their conversation. Crawshay took up the receiver. It was Henshaw speaking. "I made a mistake about the uniform, sir," he announced. "The young man is in the Canadian Flying Corps and he is the young lady's brother. He is called Captain Beverley." "Her brother!" Crawshay exclaimed.
