"About noon."
"Did you see Mr. Scott the day or evening preceding Mr. Mainwaring's death?"
"No, sir; but I know he was locked in Mr. Mainwaring's library all the afternoon, after the folks had gone out driving."
"How do you know the library was locked?"
"I was sweeping in the corridor, and I heard him unlock the door when the butler came up with some gentleman's card."
"Did you see the gentleman who came up-stairs later?"
"No, sir."
"Did you see Walter LaGrange at any time during yesterday forenoon?"
The witness colored slightly, but replied, "I think I met him once or twice; I don't remember just when."
"He was away from home part of the time, was he not?"
