Sanctum Books presents two more 1939 novels starring the cowled crimefighter whose adventures paralleled Batman's and inspired Two-Face's origin, written by Norman A. Daniels as "G. Wayman Jones" for future Batman editors Mort Weisinger and Jack Schiff. First, mass murders set the Nemesis of Crime in pursuit of a ring of satanic killers as "The Black Bat Strikes Again." Then, "The Black Bat's Challenge" is to unmask the hidden leader of a vicious gang of beggars! Plus, "The Mask Returns!" in a rare 1940 Golden Age classic from Nedor's Exciting Comics #2.
