“Yes, just that.”

“Why haven’t you told this before?”

“I attached no importance to it. In fact, I had forgotten it.”

“And what brought it again to your mind?”

“Nothing especial. I was going over the events of that night, to think if there was anything else I could tell Mr. Moore. I didn’t know he was going to throw me!”

Keeley laughed outright. Ames spoke so like an aggrieved child.

“I haven’t thrown you, Mr. Ames,” he declared. “I’m sure you and I are going to work together. I’m awfully interested in the chap who drummed along your door. I believe it was the murderer himself.”

“You do!” Ames turned a friendly look on Kee. “Then you can run him down?”

“I hope so. Now, tell us, who is it you’re shielding?”

“Nobody. Honest. But this sound in the hall was worrying my conscience.”
