Gr. 6-8. P.C. Hawke is a 15-year-old high-school student cum private detective. He gets access to murder cases through his best friend and detective partner, Mackenzie Riggs, whose mother is the New York City coroner. This new P. C. Hawke mystery involves the death of a much-hated celebrity scientist at the Bronx Zoo. The victim was first chewed on by a jaguar and finished off with a transfusion of gorilla blood. In the course of their investigations, P. C and Mackenzie are menaced by a dominant silverback gorilla, chased by a madman with a titanium machete, and cornered by a group of jaguars before they are rescued and solve the crime. P. C. describes all of this in a first-person voice that combines contemporary teen jargon with the traditional, super-cool delivery of the hardboiled detective. The contrivances may disappoint some readers, but the exotic zoo setting and exciting action scenes will hook others.Todd Morning
