In "The Zarkov Line," Flash Gordon races to save Dr. Zarkov and Dale Arden from Ming's raiders, who've hijacked an asteroid defense system as a cover for a daring kidnapping. Written by Paul S. Newman and illustrated by Frank Thorne, this 1953 adventure sees Flash captured on Mongo, where Ming's daughter Zara devises a dangerous plan to return to Earth and sabotage the very defenses she claims to be protecting.
