“No indeed. I am utterly at sea. Barbara! Murdered! It seems incredible.”
 
 “Now, Mr. Laverton-West, can you tell me what your own movements were on the night of November fifth?”
 
 “My movements? My movements?”
 
 Laverton-West’s voice rose in shrill protest.
 
 “Purely a matter of routine,” explained Japp. “We—er—have to ask everybody.”
 
 Charles Laverton-West looked at him with dignity.
 
 “I should hope that a man in my position might be exempt.”
 
 Japp merely waited.
 
 “I was—now let me see . . . Ah, yes. I was at the House. Left at half past ten. Went for a walk along the Embankment. Watched some of the fireworks.”
 
 “Nice to think there aren’t any plots of that kind nowadays,” said Japp cheerily.
 
 Laverton-West gave him a fish-like stare.
 
 “Then I—
 
 er—walked home.”
 
 “Reaching home—your London address is Onslow Square, I think—at what time?”
 
 “I hardly know exactly.”
 
 “Eleven? Half past?”
 
 “Somewhere about then.”
 
 “Perhaps someone let you in.”
 
 “No, I have my key.”
 
 “Meet anybody whilst you were walking?”
 
 “No—er—really, Chief Inspector, I resent these questions very much!”
 
 “I assure you, it’s just a matter of routine, Mr. Laverton-West. They aren’t personal, you know.”
 
 The reply seemed to soothe the irate M.P.
 
 “If that is all—”
 
 “That is all for the present, Mr. Laverton-West.”
 
 “You will keep me informed—”
 
 “Naturally, sir. By the way, let me introduce M. Hercule Poirot. You may have heard of him.”
 
 Mr. Laverton-West’s eye fastened itself interestedly on the little Belgian.
 
 “Yes—yes—I have heard the name.”
 
 “Monsieur,” said Poirot, his manner suddenly very foreign. “Believe me, my heart bleeds for you. Such a loss! Such agony as you must be enduring! Ah, but I will say no more. How magnificently the English hide their emotions.” He whipped out his cigarette case. “Permit me—Ah, it is empty. Japp?”
