Night Monster is a 1942 American black-and-white horror film featuring Bela Lugosi and produced and distributed by Universal Pictures Company.

In a small town bordering a swampy region, unexplained murders and rumors of mysterious happenings surround the swamp-based home of the reclusive but respected Kurt Ingston.

Already in the household are his grim-humored butler Rolf; a lecherous chauffeur, Laurie; a mannish housekeeper, Miss Judd; an Eastern mystic, Agar Singh; and Ingston's allegedly mentally ill sister, Margaret.

Coincident with the arrival of the three male physicians is the appearance of a lady psychiatrist, Dr. Lynn Harper, summoned secretly by Margaret to prove she is not insane and help her secure freedom from the control of Ingston and Miss Judd.

Following dinner, at which Ingston's conviction becomes evident that the three doctors are directly responsible for his current condition, the party witnesses an exhibition of materialization of a Sicilian skeleton by Agar Singh.

Ultimately, Dick confronts the killer outside the estate as he menaces Lynn, and discovers it is Ingston after all: by studying under Agar Singh, he has learned how to materialize arms and legs, hands and feet for himself, long enough to accomplish his evil deeds.
