In "They Lurk in the Cave!", a robotics researcher’s boyfriend unwittingly unleashes a strange new companion when his experimental robot constructs a duplicate for itself—only to find his real-life girlfriend’s reaction is far more volatile than he expected. Pete Tumlinson’s expressive art brings the eerie, mechanical mystery to life, while Bill Everett’s striking cover captures the moment of escalating tension. A 1974 Alan Class gem, this issue blends sci-fi intrigue with a chilling twist on love and possession.
