Brewing Up A Storm

Description for BREWING UP A STORM by Emma Lathen:

DRUNK WITH POWER

When a nineteen-year-old boy dies in a drunk driving accident, Madeline Underwood decides to convince the world that Kischel Brewery's "soft drink" leads young people to try the harder stuff. But Underwood faces formidable enemies: Kischel's investment bankers, including the unmistakable John Putnam Thatcher, their razor-sharp attorneys, and no less than the head of a Congressional committee that she's managed to publicly embarrass. So when Madeline is found dead, stuffed in the closet of the building where the committee convened, it takes all of Thatcher's acumen to sift through a long list of killers. It's the kind of case that would drive a lesser man to drink.

This is #23 in A John Putnam Thatcher Mystery.
