Less closely reasoned, more discursive, and with a few points missing, he had nevertheless contrived to evolve the whole scene with the imaginative vividness of a story-teller. He started with the buttonhook, and went on with a multitude of details — after the fashion of the novelist — which were new to Donovan. When he announced his first surprise, Depping's disguise and imposture, Patricia gave a hoot of derision, and J. R. peered over his glasses in tolerant mockery. But presently he began pounding in his details, and the others were silent.

"And I can prove my assumptions," he went on, striding back and forth among them, and addressing himself to Burke, "on points I noticed when Murch and I examined the room this morning. I decided that there had been an imposture, and I examined the body first of all… " He turned to Donovan. "You were with Dr. Fell when he went to the Guest House. Did he examine the body carefully?" Donovan was cautious. "Well, no. That is—" "On the upper lip," Morgan proceeded, "there were traces of spirit-gum for the moustache; you can't take it off with water. Traces of the actor's cement were behind his ears. In the fireplace were not only remnants of burned clothing, but a scorched tuft of black hair from the wig… Then I went into his bedroom and bathroom, which adjoined the study. If there had been any further need for confirmation, it was there. On either side of the mirror over the washbowl in the bathroom, two candles had been propped up — to give Depping light in taking off his makeup, immediately after his return. Stuck in the drain was one of those strips of transparent fishskin that are used for drawing in sagging flesh round the cheeks and eyes, to present an appearance of youth. There were wet socks and a suit of wet underclothing across a chair; the rest had been burned. I didn't find any box of cosmetics, but Murch was watching and I couldn't make a thorough search. All this puzzled Murch considerably." Again he peered at Hugh in the gloom. "What did Dr. Fell make of it?"

This time Hugh was caught off guard. "We didn't go in there," he replied. "When he deduced all you've said, it was only from the facts we'd heard—"

There was a silence. He heard his own words as though they had come back to him in an echo. Suddenly he tried to stumble into another explanation, but he could think of nothing. In the hush Morgan walked across, his head bent forward.

"Good God," he said, "do you mean to tell me that I'm right?"

There was a sort of staggered incredulity in his tone which puzzled Hugh still more.

"Right?" he repeated. "Well, if you've been saying all this-"

‘I know" said Morgan, and passed a hand over his eyes. Then he started to laugh. I’d convinced myself of it, but… well, it seemed too good to be true. It was so exactly the way it should have happened according to romance that I didn't really believe it myself. That was why I was testing it out on all of you. Betrayed, by the Lord! Master mind betrayed into telling the true facts too soon." He picked up the cocktail shaker, found it was empty, and set it down irritably. "Why the devil couldn't I have waited and hit the bishop in the eye with it? Ill never forgive myself for this."

He sat down. J. R. was making protesting noises.

"Look here," he said, "do you mean to tell me Gideon Fell believes all this tommyrot?"
