"You can talk to me like that, knowing what you know! After what you've done to me you want to pass me on to someone else. That finishes it! Now you listen. George Dale's a booking clerk at Victoria Station. He recognised you, though you didn't him."
"Quite possibly, if he was on the other side of the peep-hole, and seeing that I've only seen him two or three times in my life."
"He gave you your ticket for the Pullman. All the seats are numbered; he made a note of your number. Your ticket wasn't among those which were given up by the passengers who came back by the Pullman, but it was among those which were collected from the train which reached Victoria at 11.30. The guard saw you get into the train at Redhill Station. You got into a first-class compartment with a little man. You two were the only first-class passengers who got in at Redhill, so he took particular notice. You were in the London Bridge part of the train. At East Croydon someone else got into your compartment. You got out and went back to the Victoria part. The guard, shutting your carriage door, took particular notice of you again."
"Your friend the guard appears to be as quick to observe as he is to impart the fruits of his observation."
"He wasn't my friend, only Mr. Dale introduced me to him, and he was kind enough to answer a question or two. Mr. Dale also introduced me to the guard of the train in which your uncle was. I asked him if it stopped anywhere. He thought a bit, and then said that it did once, for about a minute, in Redhill tunnel, because the signal was against it. I haven't made inquiries yet, but I shouldn't be surprised if someone saw you get into your uncle's train at Brighton. As that train stopped in Redhill tunnel, it's not hard to understand how, or why, you got into another train a little later at Redhill Station."
"You surprise me, Mabel. I hadn't a ghost of an idea that you had such a genius for ferreting."
"It's easy enough. If that coroner hadn't had a notion in his head when he started, he might have got at the facts as easily as I have."
"And, from what you call the facts, what is the inference you draw? What dreadful charge against me have you been formulating in your mind?"
"Rodney, a wife can't give evidence against her husband in a charge of murder."
"I believe I have heard as much. And then?"
