"I can get to work now, Mr. Winbush," said Quarles. "Your master tells you to do whatever I advise. Of course, I understand that in keeping these facts to yourself you were acting in your master's interests, but were it generally known that you had suppressed the truth you might get into trouble. Have you any relatives in town?" "I have a married nephew out Hampstead way." "Most fortunate. You go straight off and see him, get him to put you up for the night, but whatever you do keep away from Jermyn Street until to-morrow morning. You will spoil my efforts on your master's behalf if you turn up at the flat before then." Winbush promised to obey these instructions, and Quarles and I left the Blue Lion. "After hearing that Lanning was coming to see me this afternoon, I telephoned a telegram to Winbush," explained the professor when we were outside. "He thought it came from his master telling him to meet him at the Blue Lion. Lanning will have to do his own packing for once. Winbush's story is rather a surprising one, eh, Wigan?" "And most unexpected," I said. "Well, no, not quite unexpected," he answered in that superior manner which is so exasperating at times. "I got that note from Lanning for the purpose of getting the man to tell me the truth." "At any rate, you were mistaken in supposing that Mademoiselle's mysterious foreigner would be at the Blue Lion," I returned. "Not at all. He was there." "Winbush!" I exclaimed. "No, Christopher Quarles. I called on Mademoiselle Duplaix this morning. I thought she would communicate directly or indirectly with Lanning; that is why I was expecting a message from him. I was also fortunate enough to appropriate her handkerchief. To-night I become the distinguished foreigner again; you had better be an elderly gentleman with a stoop. We are traveling to Harwich. Don't forget a revolver; it may be useful. We must get to Liverpool Street early; we shall want plenty of time at the station." He left me without waiting to be questioned. I was annoyed, and was pretty certain that he had overlooked one important fact. Surely Lanning must have realized how dangerous it was to give such a note to Quarles? Knowing the story Winbush could tell, he would not have been deceived by the statement that the letter was intended for Mademoiselle Duplaix. He was far too clever for that. He and Winbush were no doubt working together, and the man's story was no doubt part of an arranged scheme. It seemed to me that the immediate recognition of the second scent was suspicious. The man was probably prepared for the test. I thought it likely that Quarles had met his match this time, and I did not expect to see Richard Lanning at the station. However, he was there with Mr. Nixon. "Are they both in it?" I asked Quarles as we watched them. "No, I don't think so," was his doubtful answer.
