Les Inconnus dans la maison (The Strangers in the House) is a novel by Belgian author Georges Simenon.

An English translation by Geoffrey Sainsbury was published in the UK in 1951; it was reissued by New York Review Books Classics in 2006 with an introduction by P.D.

Throwing away his law career in favor of alcoholism and reading, Hector paid little attention to his daughter Nicole, unsure if he was even her true father.

An adaptation and remake of the French film followed in 1967, starring James Mason and Bobby Darin as the fallen lawyer and the young man accused of murder.
