Comments:
Robby Reed becomes Gill Man, Human Icicle, and Strata Man in this story.

This is the final Dial H for Hero story in House of Mystery.

Synopsis:
Robby Reed uses his H-Dial to become Gill Man and pursue the Speed Boys. He catches them trying to steal a race horse. Robby stops them, then is overcome by a strange compulsion to steal the horse himself.

Puzzled by his odd behavior, Robby becomes another hero, the Human Icicle. This time he stops the Speed Boys from stealing a race car. Once again, Robby steals the car under another bizarre compulsion.

Robby vows to make one more attempt to stop the Speed Boys, then turn himself in to police. He battles the crooks while they try to steal a speed boat. The compulsion to steal begins again, but this time it goes away before Robby completes his theft. He deduces that the pitch from the jet-booster the crooks used was responsible for his behavior. The booster falls into the ocean, preventing further compulsions, and Robby rounds up the gang.
