The Alphabet Murders

As quickly as you can say ABC, Poirot is on the case, pursuing gorgeous Amanda Beatrice Cross (Anita Ekberg), who confesses to the crimes in Poirot's Turkish bath. Poirot is shocked. After all, the ladies have their own facility elsewhere in the building! A befuddled British Intelligence officer (Robert Morley) galumphs along in Poirot's wake. And Margaret Rutherford and Stringer Davis of the Miss Marple movie series make surprise cameos to add even more fun to the mysterious goings-on. (official distributor synopsis)
