Some one was tugging at the hall-door bell. Presently a servant came and told our host that a policeman in the hall wished to speak to him at once. He apologised to us, and went outside, and we heard a man in heavy boots, who spoke in a low voice to him. My friend got up and walked over to the window, and opened it, and looked outside. "I should think it will be a fine night," he said. Then he jumped out. When we put our astonished heads out of the window to look for him, he was already out of sight.
