Double Sin: Poirot tells a startled Hastings he's decided to retire and suggests they take a trip to the seaside. On the way, Hastings befriends a young woman who finds she's missing some valuable antiques.
The Adventure of the Cheap Flat: An FBI agent who comes to London to try and catch a glamorous nightclub singer turned spy dismisses Poirot as a "gumshoe." Unimpressed with the pompous G-man's tactics, Poirot is drawn into the case after meeting a young couple who've gotten too good a bargain on a prime apartment.
Unlike the brash, gun-toting FBI agent (William Hootkins) in "The Adventure of the Cheap Flat," Poirot refuses to accept the obvious solution to any crime and uses his polite European manners to catch the real culprits off guard. Suchet captures the essence of Poirot's shrewdness and charm with such marvelously subtle gestures as lighting a suspect's cigarette while recounting the details of her crime. In "Double Sin" and "The Cornish Mystery," Poirot travels to the Lake District and Cornwall, giving viewers the benefit of beautiful scenery in addition to a delicious mystery. Like Suchet, the producers of the series paid meticulous attention to detail when creating the sets and costumes, and the results are sure to delight Christie fans and make new ones. --Larisa Lomacky Moore
