Beyond the Door by Philip K. Dick, Science Fiction, Fantasy

"Did you ever wonder at the lonely life the bird in a cuckoo clock has to lead --" wrote the editor of Fantastic Universe in January, 1954, blurbing this tale "-- that it might possibly love and hate just as easily as a real animal of flesh and blood? Philip Dick used that idea for this brief fantasy tale. We're sure that after reading it you'll give cuckoo clocks more respect."
