Mondays are seriously bad days for Megan Malone, owner of a travel agency in the Rogers Park neighborhood of Chicago. She stumbles across a murder victim and recognizes the man fleeing the scene as the same man who has scammed her agency. She's threatened and firebombed, locked in a closet at Amsterdam's Schiphol Airport, and dumped by Matthew Ganzer, the Homicide Detective she's fallen in love with - all on Mondays one spring. Her quirky friends, Bertie the florist, Dahlia co-owner of her travel agency, Yoo Hoo the neighbor, and Matthew's partner, Steve, save their lives in the riveting unfolding of the rest of the murder case while Megan and Matthew must come to terms with their true feelings for each other as the case wraps up.
