"Who came out first?"
"The canal-man."
"Was he alone?"
"Yes."
"How long before any one else came out?"
"Five minutes anyway, perhaps ten."
"What did your friend do?"
"He went out of the bank and that's the last I saw of him."
"You don't know then whether he went to the hotel or the station, or came down the river."
"I have told you just what I know and all I know. I can't do any more."
