His novel Auntie Mame: An Irreverent Escapade (1955) was one of the bestselling American books of the 20th century. In chronological vignettes, the narrator — also named Patrick — recalls his adventures growing up under the wing of his madcap aunt, Mame Dennis. Dennis wrote a sequel, Around the World with Auntie Mame, in 1958.
