The Secret 6 are back! Fresh from demolishing The Red Shadow in their first exploit, the mysterious adventurer known as King, backed by an army of underworld informants, leads the Secret 6 into new catacombs of horror and peril. When wealthy James Waldroff rises from his own tomb to walk the Earth again, King and his team are propelled along a trail of terror that leads to a haunted Mayan ruin ruled by the weird Bat-Man and his army of the undead. The macabre hunt begins in the House of Walking Corpses, but climaxes in a Zombie-infested hell. Also included are two stories by Robert Jasper Hogan under pen names, “Mystery Bones” and “Ice Patrol.”
