Bree Watson traded her lab coat for a trench coat, expecting the life of a spy to be fun. But when a body turns up on her undercover mission, she's forced to handle:

•A murdered woman with more enemies than meets the eye

•A hunky handler posing as her fake boyfriend

•A sexy detective bent on wooing her - and wooing her away from espionage

•A drop-out drug dog with a nose for trouble

•Her cranky cat, curious coworkers, a cupcake challenge she can't resist, and too many secrets, lies and cover identities to keep straight...

In the whirlwind of investigations and undercover operations, Bree develops a serious identity crisis. Who is she really? A spy pretending to be a chemist? Or a chemist playing at being a spy?
