Operator #5: The Army of the Dead by Curtis Steele

ZOMBIES MARCHED . . . soulless storm troops of a sinister madman's plot. Freedom was in mortal peril - as was Jimmy Christopher, Operator 5 of the nation's spy service, battling the bloody tide that swirled on land and sea. Into Death's Temple Jimmy rushed headlong . . . where the archfiend awaited, eager to sacrifice him on the bloody altar of tyranny . . . and resurrect him as a mindless recruit in . . . THE ARMY OF THE DEAD!
