Anthony explained it. It was some time before he could make his host believe that he was not pulling his leg. When he had succeeded in convincing him of his seriousness Fountain at once demanded to know who the man was. Anthony said that he didn't know, though he had a strong suspicion.

"Collins?" Fountain said, lowering his voice. "Good Lord!"

"Mind you, I'm not sure," Corkran warned him. "I never saw his face."

Fountain took no trouble to disguise the fact that he was thoroughly annoyed. He said that it looked as though he would have to sack the man. Anthony heartily agreed, but was himself annoyed to discover that Fountain was still somewhat dubious about his story. He remarked that it seemed fantastic; he wished Anthony had caught the man and unmasked him. As far as he could see, it would be most unwise for him to accuse Collins without any sort of proof to go on. He must think the whole thing over and keep a strict watch. It was all most unfortunate, not to say infuriating. If the police came to question the servants again the housekeeper for one would leave. She had been thoroughly affronted and upset already by the inspector's tactless method of interrogation. "In fact," said Fountain crossly, "I wish to God you hadn't looked out of your window. At least I shouldn't have known anything about it then."

At that moment Joan came into the room, and the discussion at once ended. She and Corkran were going to play golf. A polite suggestion that Basil should come and make it a three-ball match was refused. He was not going to play gooseberry, he said; besides which that old footler, Matthews, had rung up to say that he was coming round to see him on a matter of business.

"Of course I know what that means," Fountain said. "He dropped a hint at dinner last night, but I wasn't having any. I've got quite enough to worry me without the delinquencies of my head-keeper being added to the list."

"Poachers?" Joan inquired. "I know; Felicity was talking about it. I suppose Hitchcock is fairly slack."

"Well, I'm not going to get rid of him to please old Matthews," said Fountain.

Sir Humphrey was driven over at twelve o'clock by his daughter in her runabout, Ludlow being smitten with influenza. Baker ushered them both into the library and left them there while he went to find his master.

Sir Humphrey, after the manner of book-lovers, began to wander round studying the closely packed shelves. He said severely that he wondered Fountain had not had the library catalogued and arranged in decent order.
