Beyond the Door

"Beyond the Door" is a short story by Philip K. Dick, first published in the January 1954 issue of Fantastic Universe. The narrative centers on Larry Thomas, who purchases a German-made cuckoo clock for his wife, Doris, reminiscent of one her mother owned. Doris becomes enamored with the clock, believing the cuckoo favors her while disliking Larry. Unbeknownst to Larry, Doris is involved with Bob Chambers, an antique enthusiast. One day, Larry unexpectedly discovers Doris and Bob together at their home, leading him to expel them both but retain the clock, asserting his ownership. In the ensuing solitude, Larry becomes fixated on the clock, particularly irritated by the cuckoo's inconsistent appearances. His frustration culminates in a confrontation where, upon threatening the clock with a hammer, the cuckoo emerges, striking him in the eye. This causes Larry to fall and break his neck, resulting in his death. While a doctor rules the death accidental, Bob suspects there might be more to the story. 
This tale delves into themes of jealousy, infidelity, and the uncanny, illustrating how an ordinary object can become central to human emotions and relationships. Dick's narrative invites readers to ponder the boundaries between the animate and inanimate, as well as the unforeseen consequences of personal actions.
