Black Bat Double Novel #2 Black Bat Strikes Again

"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."
