A fast-paced crime thriller by James Patterson and Jeffrey J. Keyes, published in 2016 as part of Patterson's BookShots series. It serves as a prequel introducing detective Caleb Rooney, who later stars in the full-length novel The Chef.

Caleb Rooney lives a double life in New Orleans. By day, he is a dedicated homicide detective with the New Orleans Police Department. In his spare time, he works at his popular food truck, Killer Chef, serving gourmet meals across the city.

When diners at some of New Orleans' finest restaurants begin dying from deliberate poisoning, panic spreads through the city's culinary scene. The murders appear unrelated at first, but Caleb soon realizes someone is targeting the restaurant industry with meticulous planning and a deeply personal motive.

Balancing long hours as both chef and detective, Caleb follows a trail of clues through upscale restaurants, food suppliers, and the city's vibrant culinary culture. As the investigation intensifies, he races to identify a killer whose thirst for revenge threatens to claim more innocent lives before striking again.

Written in Patterson's trademark style of short chapters and relentless pacing, Killer Chef delivers an entertaining mystery that can be finished in just a few hours while introducing a charismatic new detective.
