Atomic scrambling has left Abysmii a living skeleton, so David, Kaela and Allen will have to finish their analysis of Doctor Satan’s current cruel scheme. With Ascott Keane closing in, will the diabolical villain be able to follow through with his plan? Or will the power of his mysterious ray see both of them cut down to size (pun intended)?

Story by Paul Ernst, first published in Weird Tales, October 1935.
