Tower of Shadows #7

A gigantic, mutant crab is sighted terrorizing various islands in the South Pacific. When the American military learn of this, they assign Commander Hartnell to put a stop to the crustacean threat that has become known as Titano. Hartnell's crew has several encounters with Titano and they eventually lure him to the Arctic. Hartnell maneuvers his ship so deftly that he manages to trap Titano between two giant glaciers.
