The winds of change are blowing, bringing gentrification to Callahan Garrity's funky Atlanta neighborhood. Though it probably won't harm her House Mouse housecleaning service, not everyone welcomes the rebirth. And when the body of a murdered microbrewer is discovered in the aftermath of a furious Halloween gale, suspicion falls on the aging "flower child" shopkeeper whom the victim put out of business.A former cop, Callahan isn't as quick to condemn a colorful local character as some law officers still on the force. But her investigative zeal is stirring up secrets that are forcing her to reassess old friendships and a one-time love -- and is brewing up more lethal trouble than Callahan and her "mice" can safely swallow.
