Three of the Pulp Era's greatest heroes - The Black Bat, The Domino Lady, and Inspector Legrasse - band together to battle nightmare and ninjas in one of the wildest, most exciting adventure novels of all time! In the opening days of WWII, the free world sat in dread anticipation as the Axis turned its deadly attention on one country after another. With an eye to invade the United States, the Japanese high command settles on a dark and terrible plan, employing damnable sorcery and horror from beyond to cripple the American colossus. But the USA still has a secret weapon - and The Black Bat, the Domino Lady, and Inspector Legrasse are prepared to strike back for freedom! This edition also includes "Only an Hour" a new Black Bat solo adventure by C.J. Henderson. Introduction ("Who the Hell Are These Guys") by Ron Fortier. "If as some argue, the hardboiled private eye mystery story is a literary form on a par with the Japanese haiku or Irish ballad, then Mr. Henderson deserves the mantle of literary master." - New Mystery Magazine
