The Barefoot Stiff. Maggie Sullivan mysteries

(This short story features characters from the author's Maggie Sullivan mysteries series.)Depression-era private investigator Maggie Sullivan knows how to be tough when she needs to and polish her nails when she doesn't. A job offer from a blonde at a dime store lunch counter lures her to a still-warm corpse in an alley. His gold watch and cufflinks are still on him, but not his shoes and socks. A night of grilling by homicide cops does nothing to improve Maggie's mood, which deteriorates further when they laugh off a lead she gives them and imply she solves cases by batting her eyes instead of using her brains.
Aided by a ragtag newsboy, Maggie baits a trap for the killer. He shows up with a knife. But Maggie wields a .38 as expertly as she does an emery board - and she doesn't back down for thugs or authorities when she's after answers.
