The Mousetrap

by Agatha Christie

Detective Sergeant Trotter (Georgie Corrigan) Character Analysis

Claiming to be sent by the Berkshire Police, Detective Sergeant Trotter comes to Monkswell Manor to protect its residents from becoming the next victims of Maureen Stanning’s murderer—at least that’s what he claims. Trotter, a seemingly good-natured young man with a Cockney accent, arrives at the snowed-in house on skis and questions everybody to determine whether they have any connection to the murderer. When Mrs. Boyle is found dead, Trotter concludes that everyone in the manor is a possible suspect. As he enacts a plan to catch the killer, he corners Mollie and reveals his true identity: he is Georgie Corrigan, the eldest of the three children who were abused and neglected in the Longridge Farm case. After his cruel foster parents, Maureen and John Stanning, were imprisoned for their crimes, Georgie eventually entered military service. An army psychologist determined him to be mentally “unbalanced,” and Georgie later deserted. To avenge himself and his siblings on the adults who harmed them in their childhoods, Georgie strangled Maureen Stanning to death in London. Then, disguised as a police officer, he traveled to Monkswell Manor to kill Mrs. Boyle and Mollie Ralston, both of whom he considers to be complicit in his and siblings’ suffering. Before he succeeds in killing Mollie with a childlike glee, Miss Casewell reveals herself to be Georgie’s sister and convinces him to come with her to a place where he’ll be cared for. Happy to be reunited with his younger sister, Georgie allows himself to be led away and is sedated.
