Margaritas, spicy guacamole—and murder—are among this year’s preparations for Cinco de Mayo in this “delectable new mystery series” (Kate Carlisle, New York Times–bestselling author).

Tres Amigas Café chef Rita Lafitte is busy baking her green chile soufflés and chocolate flans for Cinco de Mayo. If only her friend Linda, the daughter of Rita’s octogenarian boss Flori, could get into the festive spirit. Linda’s cart, Tia Tamales, is losing business to Crepe Empire, the hottest food cart in Santa Fe. Napoleon, Crepe Empire’s owner, is a pompous, celebrity chef who wants to squeeze out the competition. But when Linda gets into a heated argument with Napoleon and his corpse is later found stabbed and pinned beneath the wheels of her tamale cart, she becomes the number one suspect.

Determined to prove Linda’s innocence, Rita investigates. From Napoleon’s disgruntled former employees to a shady health inspector, the list of suspects is longer than Flori’s strings of dried chili peppers. And when another corpse surfaces, Rita must scramble to find an elusive killer with an appetite for murder . . .
