Despite Henry's doubts, Dudley quickly charms his way into Henry's life, becoming a favorite of his maid Matilda (Elsa Lanchester), his little daughter Debby (Karolyn Grimes), his secretary, his St Bernard Queenie, and even his wife Julia, all the while preventing Henry from telling anyone what Dudley claims to be. Julia enjoys Dudley's company, delighting in his broad knowledge of the world and his ability to do seemingly everything well. Meanwhile, Henry gets no closer to building his cathedral, and becomes increasingly angry with Dudley for being so intrusive.
