"You are under a misapprehension, sir. I give you my word of honour that you are. I may have been guilty--I have been guilty--of an error of judgment, but not of a crime."
"Do you call murder an error of judgment?"
"There has been no murder--I swear it!"
He held up his hand to check me. "Let me tell you how much I know about the business before you go out of your way to lie to me." Seating himself on the edge of my writing-table, he brought his right hand down upon it now and then to emphasise his words. "Directly the train started I heard two voices in the compartment next to mine--in your compartment. The voices were raised in quarrelling. I had, by the purest accident, seen a woman get into your compartment just as we were leaving Brighton, and I knew that the voices were yours and hers. The quarrelling got worse and worse. I feared every moment that something dreadful would happen. I was just going to sound the alarm, when there was silence. Immediately after a door banged--the door of your carriage. I was afraid that something dreadful had happened. And yet, I told myself, if nothing had happened I should look foolish if I stopped the train. Unable to make up my mind what to do, I did nothing. When on reaching Victoria I made a bolt for your carriage and found that the woman was not there, I saw that my worst fears were realised. Then I understood the sudden silence, and the banging of the door."
"She had fallen out."
"Fallen out?"
"Yes."
"Who opened the door for her to fall?"
"I did." Seeing the slip I had made I endeavoured to correct myself. "That is, I opened the door with the intention of leaving the carriage, in order to escape her violence. In trying to prevent my leaving she herself fell out."
"If, as you say, the whole thing was an accident, why did you not sound the alarm?"
