“I did.”

“What was it?”

“That I can’t remember.”

“The boy’s book will show?”

“Sure.”

“Then,” said Kerr, rising, “we’ll look up that boy, and also try to find the exact minute at which Mr. Judson fell or was thrown from the window.”

The detective cautioned the others to say nothing about their conversation; and went out to talk with the men who had seen Judson fall.

They agreed pretty nearly as to the time of the event.

One said twenty-five minutes of four.

The other thought it was two minutes later.
