Disowned by her aristocratic relatives and stripped of her clinical license, veterinarian Nancy Summers finds herself scraping by as caretaker of a crumbling zoological park. Following a violent fever that nearly kills her, Nancy wakes up to a startling revelation: she can fluently comprehend every murmur, squawk, and bark from the animal enclosures.
When resident giraffes and an ex-military guard dog disclose chilling details of an active serial killer, Nancy teams up with her detective brother to crack unsolved felonies. As her uncanny crime-solving skills embarrass the corrupt elite who discarded her, Nancy turns her furry informants into the city’s ultimate investigative unit.
