"Parrish told me he was in Italy for some time," I said.
"The first letter took me to Liverpool," Quarles went on. "Thorn's Hotel is third-rate, but quite good enough for a man who does not want to burn money. 'C.M.' stands for Claude Milne. That was the only name with those initials in the hotel books on that date. He had come from New York, and he left an address to which letters were to be forwarded, an hotel in Craven Street. I traced him there. He stayed a week, and, I gather, spent a rollicking time, mostly returning to bed in the early hours not too sober. No friends seem to have looked him up. He appears to have gone abroad again."
"And it is eighteen months ago," I said.
"Exactly. We will remember that," said Quarles. "The other letter is older still. It is evidently a warning. The writer believed Parrish to be in danger from this 'B.' who was coming to England. Now, was it B. who found him the other night after three years' search?"
"The name is on the door and in the directory," I answered.
"That is another point to remember, Wigan. Now, I daresay you have learnt from your inquiries in the building that very little was known about Parrish. Some of the tenants did not remember there was such a name on the door. I have interviewed the agents who receive the rent, and they tell me that until about three years ago they received Parrish's rent by check, always sent from Windsor, and on a bank at Windsor; but since then they have received it in cash, promptly, and sent by messenger boy, the receipt always being waited for. They inform me that at one time, at any rate, Parrish did not use his chambers much, was a river man in the summer, and in the winter was abroad a great deal. The letter sent with the cash was merely a typed memorandum. There was no typewriter in Parrish's chambers, I think?"
"No."
Quarles took from some papers the fly-leaf he had torn from one of the books.
"That is Parish's signature," said Quarles. "The agents recognize it, the bank confirms it; the account is not closed, but has not been used for three years. The rooms he occupied in Windsor are now in other hands, and nothing is known of him there. Inspector Cockran made these inquiries at Windsor. You see, as you are off the case I am helping him. Having no official position in the matter I must attach myself to some one to facilitate my investigation. Cockran thinks I am an old fool with lucid moments, during which I may possibly say something which is worth listening to."
"He is generally looked upon as a smart man," I said.
