Generate a question about the following movie plot: A group of five renowned detectives, each accompanied by a relative or associate, is invited to "dinner and a murder" by the mysterious Lionel Twain. Having lured his guests to his mansion managed by a blind butler named Jamessir Bensonmum, who is later joined by a deaf-mute, illiterate cook named Yetta, Twain joins his guests at dinner. The house is then sealed off. Twain announces that he is the greatest detective in the world. To prove his claim, he challenges the guests to solve a murder which will take place at midnight; a reward of $1 million will be presented to the winner. Before midnight the butler is found dead and Twain disappears, only to re-appear dead from a stab wound immediately after midnight; the cook is also discovered to have been an animated mannequin, now packed in a storage crate.

At first the butler plays the part of each of the persons, male or female, with whom he is identified, but then he pulls off a mask to reveal Lionel Twain himself, alive.
