The Wrong Murder — Craig Rice

A cynical Chicago attorney butts heads with a beautiful killer socialite -- from “the Dorothy Parker of detective fiction” (William Ruehlmann).
 
Press agent Jake Justus doesn't care if all of Chicago drops dead. He's just tied the knot with debutante Helene Brand, and a Bermuda honeymoon is only three in-flight martinis away. But the shooting death of a man in broad daylight, on the busiest shopping day of the year, with plenty of witnesses, is particularly ill timed. Jake's pal, attorney John J. Malone, agrees. Only a day before, wedding guest Mona McClane, notorious jetsetter and tipsy big-game hunter, bet the two men she could bag an innocent stranger and they'd never be able to prove a thing.
 
Then Malone discovers that the victim wasn't so innocent. Any number of people wanted him dead. And if Mona is only one of them, Malone's wagering there's much more to this murder than just the thrill of getting away with it.
 
The first mystery writer to ever make the cover of Time magazine, Craig Rice was known for her fizzy cocktails of hard-boiled noir and screwball comedy, prompting the New York Times to ask: “Why can't all murders be as funny as those concocted by Craig Rice?”
