No Pockets in a Shroud: A Smashing Detective Story (Black Mask)

Two gambling kingpins go to war—and Manville Moon is caught in the middle
When an upstart gangster named Byron Wade threatens Louis Bagnell’s gambling empire, Bagnell attempts to hire Manville Moon, a detective whose loss of a leg has not diminished his reputation as a tough guy. Preferring to remain neutral, Moon turns down Bagnell’s offer and refuses Wade’s as well. But Wade does not want another gunman. He wants a sleuth—to investigate his own murder, should the coming war leave him dead. They are negotiating over a platter of chop suey when Louis Bagnell turns up murdered.
Was Wade using Moon as an alibi, or did Bagnell’s killer come from within his own gang? Double-crosses come faster than bullets in this twisting novella, but even on one leg, Manville Moon will have no trouble keeping up.
