Fan Casting Clue

n 1954, six strangers arrive by ominous invitation at a secluded New England mansion, despite most of the guests being from the Washington, D.C., metropolitan area. Greeted by Wadsworth the butler and Yvette the maid, each guest receives a pseudonym: Colonel Mustard, Mrs. White, Mrs. Peacock, Mr. Green, Professor Plum, and Miss Scarlet.

A seventh guest arrives, Mr. Boddy, who Wadsworth reveals has been blackmailing the others: Mrs. Peacock is accused of taking bribes for her husband, a US senator, but denies any wrongdoing and claims she has paid the blackmail to keep the scandal quiet; Mrs. White is suspected in the death of her husband, a nuclear physicist, she denies guilt and states that she does not want the allegations made public; Professor Plum has lost his medical license due to an affair with a patient, he initially denies this; Miss Scarlet runs an underground brothel in Washington, D.C., a title she gladly flaunts; Colonel Mustard, though initially suspected of being one of Miss Scarlet's clients, is actually a war profiteer who sold plane parts on the black market, resulting in several deaths; Mr. Green is a homosexual, a secret he isn't ashamed of, but must keep secret as it would cost him his job at the State Department if anyone found out.
