Valiant #27 October 1962 [4]

In "null," Louis Crandell, once a quiet assistant to Professor Barringer, becomes a man haunted by his own invisibility after a lab accident leaves only his steel prosthetic hand visible. Driven by a fractured mind and a growing obsession with power, he turns to crime across England, then vanishes into New York, where he threatens the city with a bomb. As the manhunt intensifies, his path crosses with a gangster, and for the first time, Crandell begins to question the darkness he’s embraced.
