Dark Tort (Goldy Culinary) by Diane Mott Davidson

Just because the police are on the case doesn't mean Goldy can't do a little snooping herself. While catering a party at the home of one of the firm's lawyers, she just happens to overhear an incriminating conversation. She also discovers a few tasty clues in the kitchen. Before long, Goldy finds herself knee-deep in suspects. But one of them is incredibly dangerous . . . and very liable to cook Goldy's goose.
