glanced around to assure himself that no other person was within earshot;
then he said vehemently:

"I tell you, Mr. Brett, that swine killed Sir Alan Hume-Frazer."

"You use strong language."

"Not stronger than he deserves."

"What are you doing here?"

"I heard he was in London, and watched him. I saw him go to your chambers
and guessed what was up, so I came down here to see you and tell you what
I know."

"Out of pure good-nature?"

"You can believe it or not, Mr. Brett. It is the truth."

"He has been tried and acquitted. He cannot be tried again. Does Scotland
Yard--"

"I'm on my holidays."

Brett laughed heartily.

"I see!" he cried. "A 'bus-driver's holiday! For how long?"

"Fourteen days."
