"Beyond the Door" by Philip K. Dick is a short story first published in 1954. When Larry Thomas buys his wife Doris a cuckoo clock, she becomes convinced the little bird likes her but dislikes him. As Larry's marriage crumbles and his wife's affair comes to light, he finds himself alone with the clock—and increasingly at odds with its mechanical occupant. A darkly unsettling tale that blurs the line between the ordinary and the inexplicable. (This is an automatically generated summary.)
