"Where did you go?" insisted Bristow.
"I took a walk. That was all. I didn't feel like sleeping."
"Did you see anybody while you were walking?"
"Not that I remember. Why?"
"Because, if you did, it might be advisable for you to remember. It may become necessary for you to prove an alibi."
"Oh, that!" the young man said with a nervous laugh.
"Yes. Can't you tell us where you went?"
"I wandered around, up and down the down-town streets. That was all."
"Well, remember," Bristow cautioned him. "If you can produce two or three people who saw you down there, it may help you a whole lot."
"Oh, that's all right, I haven't done anything against the law. The idea's absurd."
