“And Miss Langdon?”

“She always left when I did—at five o’clock. The elevator stops running then.”

“But she didn’t leave at five to-day?”

“I guess not, sir.”

“How does it come you returned to-day after your hour for going home?”

“Mr. Redway sent me on an errand.”

“What kind of an errand?”

“To take his watch to a jeweler’s on Broadway to be cleaned.”

“What time was that?”

“Ten minutes before five.”
