Trio was the 1950 follow-up to the successful Somerset Maugham "omnibus" feature Quartet. Maugham himself introduces the three short playlets in this captivating collection. "The Verger" stars James Hayter as a church verger who loses his position when it is discovered that he can neither read nor write. With the help of sympathetic Kathleen Harrison, Hayter becomes a successful tobacconist, a turn of events leading inexorably to the story's beautifully ironic punchline. In "Mister Know-All," Nigel Patrick plays an obnoxious, garrulous passenger on a luxury cruise, who becomes a hero simply by knowing when to shut up. The final story, "Sanitorium," details the touching romance between tuberculosis victims Michael Rennie and Jean Simmons. Like Quartet, this was popular and successful enough to inspire a sequel, 1951's Encore.
