a poisoned beer. Roger's role in the household is changed: Instead of being Sylvia's brother-in-law, he is the piano player at Castle Savage, and since the Caymans are deleted and there is no photograph for him to take from Carstairs' body, he is not present when the body is discovered. The motive for the murders is changed: Roger and Moira are revealed to be brother and sister, children of Sylvia from her first marriage, to Jack Savage's brother George. Jack and Sylvia began an affair while the brothers were living in China shortly before the beginning of World War II, and Jack had his brother, a vocal opponent of the Japanese, murdered. As the war intensified, Jack returned to England with Sylvia but forced her to leave her children behind, where Roger was placed in an orphanage and Moira, it is implied, was used as a "comfort girl" by the Japanese army. The denouement is changed; Moira and Roger are interrupted in an attempt to kill Sylvia by injecting her with poison, but are surprised by the other suspects. During the ensuing struggle, Tom shoots Roger, and Wilson kills Moira by injecting her with the poison she intended for Sylvia.
