Based on a 1924 mystery novel by Agatha Christie, The Man in the Brown Suit was the eighth of Warner Bros. Television__APOS__s Christie-inspired TV movies. Stephanie Zimbalist stars as an American tourist in Cairo (with Spain standing in for Egypt). She runs across a mysterious murder, and an odd encounter with a stranger; all this occurs even before she sets foot on a luxury liner with an all-suspect passenger manifest. It is established that the murderer, who is after a cache of valuable diamonds, is an internationally notorious criminal--but which one of the passengers is he (or she)? Maybe the villain romantic lead Simon Dutton, the __QUOTE__man in the brown suit__QUOTE__ of the title...but don__APOS__t discount such special guest suspects as Rue McClanahan and Tony Randall.
