Flash, Dale, and Dr. Zarkov return from their former space adventures only to find that their enemy, Ming the Merciless of planet Mongo, has a new weapon: a deadly ray that crosses space to wreak havoc on earth. Earth’s only hope is for our heroes to take off again and stop the ray at its source on Mars, where they (and a stowaway) must battle Ming’s ally, Queen Azura, who turns her enemies into lumpish clay people. Can they survive 15 chapters of deadly perils? Find out next week…
