“My dear Smith, you are talking wildly. Let me beg you to go to bed.”

“On the contrary, I never spoke so deliberately in my life. And I will promise to go to bed the moment you have signed it.”

“Arrested? For what?”

“For murder. It is quite on the cards. I wish to be ready for every event. There is only one course open to me, and I am determined to take it.”

“For Heaven’s sake, don’t do anything rash!”
