Danger creeps close to home when former FBI profiler-turned-Paris bookshop owner Hugo Marston must investigate the death of his friend—a French sommelier—in this stylish and suspenseful mystery for fans of Charles Finch, Ann Cleeves, and Martin Walker.

When police Lieutenant Camille Lerens shows up at Hugo's Mystery and Antiquarian Bookshop, it's clear she hasn't come for a book recommendation. She needs his help. An attempted carjacking in Montmartre was foiled by a passerby. In the scuffle, the masked culprit was shot and killed with his own gun. However, the driver, the victim, refuses to reveal his identity, insisting he will speak only to Hugo Marston. There's good reason for this—the driver is in witness protection. Hugo knows, because he put him there. The question is, was this a random carjacking—or a calculated attack on the former mob accountant?

As Hugo is drawn into the case, another mystery presents itself while he dines with sommelier Christina Valdez. The appearance of a man lurking across the street from the restaurant prompts her to reveal that she's being followed. Who stalks a sommelier? Hugo plans to find out.

But there's more. Hugo soon uncovers a mystery in his very own mystery bookshop. Beneath loose floorboards lies a wooden box containing a gun, a bloody towel, and an encrypted diary. His former FBI colleague, Tom Green, helps crack the code, revealing a link to a cold case from over thirty years ago.

When bodies start turning up, Hugo must untangle the labyrinthine connections—before he, too, ends up on the wrong end of a gun . . .
