“Well?” he said wonderingly.

Antony shook his head.

“It’s all different,” he said. “For one thing, you made a devil of a noise and Cayley didn’t.”

“Perhaps you weren’t listening when Cayley went in?”

“I wasn’t. But I should have heard him if I could have heard him, and I should have remembered afterwards.”

“Perhaps Cayley shut the door after him.”

“Wait!”

He pressed his hand over his eyes and thought. It wasn’t anything which he had heard, but something which he had seen. He tried desperately hard to see it again.⁠ ⁠… He saw Cayley getting up, opening the door from the office, leaving it open and walking into the passage, turning to the door on the right, opening it, going in, and then⁠—What did his eyes see after that? If they would only tell him again!
