When sixteen-year-old Beka becomes "Puppy" to a pair of "Dogs," as the Provost's Guards are called, she uses her police training, natural abilities, and a touch of magic to help them solve the case of a murdered baby in Tortall's Lower City.

Beka, having just lost her fiancé in a slaver's raid, is able to distract herself by going with her team on an important hunt at the queen's request, unaware that the throne of Tortall depends on their success.
