Effective psychological love story with a macabre twist not found in the original Joy Cowley novel. The dreary existence of middle- aged spinster Maura Prince takes an unexpected turn with the arrival of young handyman Billy Jarvis, but there is more to Billy than meets the eye. This well-crafted film, full of sexual tension and Gothic flavor, was Patricia Neal`s second after her return to acting, her real-life stroke worked deftly into the story by then-husband Roald Dahl.
