Doctor Solar, Man of the Atom #5

Solar's experiments create a new crystalline element. When he takes it to New York to consult with specialist Wolson, two thieves kill Wolson. The unknown crystal expends, engulfing Solar and the killers, until Solar finds a way to break it. The thieves insist that Solar has strange powers, but everyone considers their testimony a crude attempt at an insanity plea, and they are sentenced to death.
