We Have Always Lived in the Castle is a 1962 mystery novel by American author Shirley Jackson. It was Jackson's final work, and was published with a dedication to Pascal Covici, the publisher, three years before the author's death in 1965. The novel is written in the voice of eighteen-year-old Mary Katherine "Merricat" Blackwood, who lives with her sister and uncle on an estate in Vermont. Six years before the events of the novel, the Blackwood family experienced a tragedy that left the three survivors isolated from the rest of their small village.
