John Carter: Warlord of Mars #9

John Carter and Dejah Thoris try to unravel a mystery in lonely Martian village under attack by a mysterious killer. But even if they manage to gain the trust of the suspicious villagers, something far more deadly lurks in the shadows. It's a murder mystery, Martian-style, from the minds of Ron Marz, the fan-favorite cosmic writer of Green Lantern, and Ian Edginton!
