People say New York City is a jungle. Still, P.C. Hawke is a little surprised when his best friend, Mackenzie, invites him to tag along with her police coroner mother to examine a scientist who was mauled by jaguars at the Bronx Wildlife Conservation Park.

But when the two teenage sleuths learn that the scientist actually died because he was given a lethal dose of gorilla blood after the attack, they quickly realize that the most vicious predator imaginable is loose in the park: a human killer. And when their investigation turns up a whole herd of suspects, P.C. and Mac start to wonder whether they’re the hunters—or the prey!

In this wild addition to a series that includes The Surfing Corpse and The E-mail Murders, Pulitzer Prize–winning author Paul Zindel creates a suspenseful mystery for teens.

“… combines contemporary teen jargon with the traditional, super-cool delivery of the hardboiled detective.”—Booklist
