The Counterplot is the second novel by Hope Mirrlees. Written in 1923, it was originally published in 1924, and is the only one of Mirrlees's three novels to take place in then-contemporary settings, Madeleine: One of Love's Jansenists (1919) being a historical novel, while Lud-in-the-Mist (1926) is a fantasy.

(Helen) Hope Mirrlees was a British poet, novelist, and translator. She is best known for the 1926 Lud-in-the-Mist, an influential fantasy novel, and for Paris: A Poem (1920), an experimental poem published by Virginia and Leonard Woolf's Hogarth Press, which critic Julia Briggs deemed "modernism's lost masterpiece, a work of extraordinary energy and intensity, scope and ambition."
