Ever want to commit a murder? The Plot, Like Gravy, Thickens follows the story of Walter, the playwright's alter ego, who narrates the show under the premise that he will tell the audience how he commits a murder. He introduces the audience to tyrannical millionaire Edward Worthington's relatives, business associates, and household staff, most of whom have reason to wish the man dead. Gathered on a stormy evening at Worthington Manor to celebrate Edward's fiftieth birthday are his wife, her brother, Edward's befuddled older sister, his ex-wife, and his daughter. Also present are his shady lawyer and his uptight business manager with his giddy wife, and southern secretary, as well as the butler, the housekeeper, the maid, and the cook. Each has a motive that is established when the lights go out and the mysterious murder occurs.
