Author D.L. Champion's knack for penning quirky series characters reached a new height with his stories of skinflint shamus Rex Sackler, one of Black Mask's longest-running and most beloved series. Already a reader favorite for his Inspector Allhoff stories in Black Mask's companion title, Dime Detective, Champion chronicled the offbeat cases of Rex Sackler, the greedy gumshoe who "could squeeze a nickel till the buffalo cried uncle." The Rex Sackler series allowed Champion to display his talent for sardonic wit and humor in more than two dozen frequently hilarious novelettes published in Black Mask during the 1940s. This volume collects the next six stories, along with an all-new introduction by Karl Schadow on the long-forgotten Rex Sackler radio show.
