“Bong!” went the clock again.

Anthony pulled out his watch. The hands stood at eleven o’clock. “All right, grand-dad,” he said. “You needn’t say any more. I know the time. I wish you could tell me what happened last night instead of being so damned musical.”

The clock went on striking. Anthony wandered to the door, paused, and went back to the writing-table. As he sat down again the clock chimed its final stroke.

He felt a vague discomfort, shook it off and continued his scrutiny of the table. It was of some age, and beautiful in spite of its solidity. The red leather covering of its top had upon it many a stain of wear and inks. Yet one of these stains seemed to Anthony to differ from the general air of the others. He rubbed it with his fingers. It was raised and faintly sticky. It was at the back of the flat part of the table-top. Immediately behind it rose two tiers of drawers and pigeon-holes. Also, its length was bisected by a crack in the wood.

He rubbed at the stain again; then cursed aloud. That vague sense of something wrong in the room, something which did not fit the essential sanity of life, had returned to his head and spoilt these new thoughts.

The door opened and shut. “What’s the matter, sir? Puzzled?” Boyd came and stood behind him.

“Yes, dammit!” Anthony swung round impatiently. “This room’s getting on my nerves. Either there’s something wrong in it or I’ve got complex fan-tods. Never mind that, though. Boyd, I think I’m going to give you still more proof that there was no struggle. Come here.”

Boyd came eagerly. Anthony twisted round to face the table again.

“Attend! The body was found over there by the fireplace. If one accepts as true the indications that a struggle took place, the natural inference is that Hoode was overpowered and struck down where he was found. But we have found certain signs that lead us to believe that the struggle was, in fact, no struggle at all, and here, I think, is another which will also show that Hoode’s body was dragged over to the hearth after he had been killed.”

Boyd grew excited. “How d’you mean, sir?”
