“No!”

“No one other than Miss Trevert, I gather, heard the shot?”

“That is so!”

Mr. Manderton consulted a slip of paper which he drew from his pocket.

“Inspector Humphries,” he said, “has drawn up a rough time-table of events leading up to Mr. Parrish’s death, based on the evidence he has taken here this evening. You will tell me if it tallies.”

He read from the slip:

5 P.M. Bude sounds the gong for tea.

5.10 Mr. Greve passes Bude in the hall and goes down the corridor leading to the library. Mr. Greve states he went straight out by the side door into the gardens.

The detective looked up from his reading.

“At 5.12, let us say, Bude comes back from the servants’ quarters to the hall and hears voices from the library. He closes the passage door. Is that right?”
