The buoyant mood at Bistro Rousseau deflates when Chef Camille's sister, Renee, turns up dead in the chef's kitchen, and Mimi Rousseau must tease the real killer out of a mélange of menacing characters.

Crush Week in Nouvelle Vie is a madhouse—in a good way. Tourists pour into town for the pressing of the Napa Valley's world-renowned grapes and all the town's businesses get a nice lift, including Bistro and Maison Rousseau. Mimi is raising the ante this year with a Sweet Treats Festival, a wonderland of croissants, cakes, tarts, and soufflés crafted with expert care by the area's top talents.

Chef Camille's sister Renee is managing the festival with a cast-iron fist, upsetting everyone, including her sister. Which is bad for Camille when Renee turns up dead in the chef's kitchen. Mimi is still building her business, so her first course of action is to whip up answers and catch the unsavory perpetrator before Camille takes a dusting and gets burned.

Fans of JoAnna Carl and Joanne Fluke will want a succulent second serving of A Soufflé of Suspicion, Daryl Wood Gerber's appetizing second French Bistro mystery.
