“Where were you?”

“Here.”

“Did any one see you here?”

“Yes, sir.”

“Who?”

“Sam Archer.”

“His evidence might satisfy me, but not others. It is conceivable that a room-mate should feel in duty bound to defend his friend at the expense of a lie. Did no one else see you?”

“Yes, sir.”

“Who?”

“The man who delivers for Jetteau’s laundry, a short, red-faced fellow. We call him Pete.”
