Forbidden Worlds #75

Dr. Lyle Gordon has spent nearly four decades haunted by a terrible accident in his laboratory—a catastrophe involving his fiancée Ellen and an experimental dimension beam that he can never quite undo. When psychiatrist Dr. Vincent H. Carr arrives hoping to help the troubled scientist recover a forgotten memory, he uncovers the stunning truth behind Gordon's lifelong search. As the past comes rushing back, a desperate hope emerges that Ellen might finally be found—if only the right number can be remembered.

Professor Bordoni's revolutionary vehicle proves it can do far more than race—it can drive, fly, and swim with equal mastery. When he activates a mysterious "X position" switch on a desert highway, a blinding flash transports him to an alien dimension, where his arrival is met not with welcome but with gunfire and accusations of madness. Now stranded in a world that dismisses his impossible story, Bordoni must face the consequences of his greatest invention's most dangerous capability.
