FBI Boston’s Eurasian Organized Crime squad is buried in Basement Level 3, a place that smells of old paper and defeat. It’s where careers go to die.

Enter Probationary Agent Emma Sterling. She arrives like a glitter bomb in a library, armed with a red tin of homemade snickerdoodles and a relentlessly sunny Midwestern disposition. She’s assigned to Special Agent Liam Reeve, a cynical, rumpled veteran who’s spent twelve years hunting a ghost and has zero patience for a rookie who looks like she belongs in a rom-com.

But when a confidential informant is executed, Emma’s mask slips. At the crime scene she reads the grisly details with an unsettling fluency that unnerves her partner. Beneath the snickerdoodles and the smile lies a razor-sharp instinct and a secret agenda.

Emma isn’t just in Boston to learn the ropes. She’s there to hunt Viktor Mirsky, a man the FBI considers a washed-up relic but who she knows is the central bank for the American underworld, using the elite art market to launder billions.

As Liam and Emma navigate a dangerous partnership, they uncover a conspiracy that links the gritty streets of East Boston to the champagne-soaked galas of the art world. But the closer they get to the truth, the harder it becomes for Emma to keep her secrets. If her cover’s blown, she loses everything.
