The Truth About murder in the Alley

There are many doubts in this case, suspect 1: 9 cigarette butts were found in the room of the deceased Allen, and when the inspector and Poirot and others entered the room, although the door and window were closed, they could not smell any smoke, which indicated that there was no smoking in the house, and the cigarette butts were transferred to the room after smoking; Suspicion 2: The watch on the corpse was worn on the right hand, and the ink bottle position and pen holder on the table in the room were also on the left hand side, which were the habits of the left hand, but Prenderley said that Allen was the right hand.

Judging from these two key doubts and the performance of Prenderley, Charles, and Eustace, these three people are almost unsuspecting, And Prender is deeply in love with Alan, and she can easily find an alibi the night before when she returned to her residence in the morning of the crime; Charles is only a cold-blooded politician, and he values his reputation more than his fiancée's life; and Colonel Eustace is even less likely to kill Alan, because it is he who is secretly blackmailing Alan, and Allen is his "treasury". The only people in the case who are in conflict are probably Prenderley and Eustace, and based on this, Poirot gives the most reasonable reasoning.

Returning to the shared apartment in the morning of the Prenderley crime, she found her beloved Alan committing suicide in a pool of blood, and she read the letter left to her by Ellen, which stated that she felt helpless because of Eustace's extortion, eustace grasped the fact that Ellen had become a wife in India and had a daughter, and decided to commit suicide because she did not want to implicate her fiancé's reputation. Grief-stricken and determined to take revenge on Colonel Eustace, Ms. Prenderley moved the objects that had proved Alan's left-handed hand, forgetting the watch, the ink bottle, and the pen holder. The colonel's blue cufflinks, which had fallen in the living room, were brought to Allen's room, the windows and doors were closed, and some of the fingerprints on the gun were erased, and a suicide disguised as murder was formed. As for the golf clubs, it can be seen from the video that these golf clubs are left-handed clubs that are specially used by left-handed players, so Poirot immediately understands everything when he sees the broken club. The inspector summed it up to the essence: this was not a murder disguised as a suicide, but a suicide disguised as a murder.
