“Mon ami Hastings! But how glad I am to see you. Veritably I have for you a great affection. And you have enjoyed yourself? You have run to and fro with the good Japp? You have interrogated and investigated to your heart’s content?”
“Poirot,” I cried, “the thing’s a dark mystery! It will never be solved.”
“It is true that we are not likely to cover ourselves with glory over it.”
“No, indeed. It’s a hard nut to crack.”
“Oh, as far as that goes, I am very good at cracking the nuts! A veritable squirrel! It is not that which embarrasses me. I know well enough who killed Mr. Harrington Pace.”
“You know? How did you find out?”
“Your illuminating answers to my wires supplied me with the truth. See here, Hastings, let us examine the facts methodically and in order. Mr. Harrington Pace is a man with a considerable fortune which at his death will doubtless pass to his nephew. Point No. 1. His nephew is known to be desperately hard up. Point No. 2. His nephew is also known to be—shall we say a man of rather loose moral fibre? Point No. 3.”
“But Roger Havering is proved to have journeyed straight up to London.”
“Précisément—and therefore, as Mr. Havering left Elmer’s Dale at 6.15, and since Mr. Pace cannot have been killed before he left, or the doctor would have spotted the time of the crime as being given wrongly when he examined the body, we conclude quite rightly, that Mr. Havering did not shoot his uncle. But there is a Mrs. Havering, Hastings.”
“Impossible! The housekeeper was with her when the shot was fired.”
