Homicide Lieutenant Jacqueline “Jack” Daniels is in some serious trouble. Her boyfriend wants to get married. Her partner wants to transfer to another department. Her dead father may not be dead after all. And a brilliant sociopath known as the Chemist is poisoning Chicago’s food supply, killing hundreds of people.

Jack is put in charge of the case. But how do you catch someone who is always in disguise, who ingeniously spreads toxins in restaurants, grocery stores, and fast-food places without leaving any clues? Time is running out. The Chemist has something big planned - something really big - and Jack has to push herself to the limits of her capabilities, or else everyone she knows and everything she holds dear will be destroyed.

In Dirty Martini, Jack faces her toughest adversary yet: a sicko who wants to murder an entire city. Can she catch him - and decide whether to accept boyfriend Latham’s surprise proposal - without destroying both her reputation and her sanity?
