Teddy Fitzroy returns as FunJungle's resident sleuth when a lion is falsely accused of killing a distinguished dog in the latest novel in New York Times bestselling author Stuart Gibbs' FunJungle series. For once, operations at the enormous zoo/theme park appear to be running smoothly (except for the occasional herring-related mishap in the penguin exhibit) and Teddy Fitzroy is finally able to give detective work a rest. But then a local lion is accused of killing a famous dog—and the dog's owner, an inflammatory radio host, goes on a crusade to have the cat declared a nuisance so it can be hunted. However, there's evidence that the lion might have been framed for murder and now a renegade animal activist wants teddy and his girlfriend Summer to help prove it—and catch the real killer. And if that wasn't enough, someone has poisoned FunJungle's beloved giraffes and the parks' owner wants Teddy on the case. Now, Teddy finds himself wrapped up in the middle of his most bizarre, hilarious, and dangerous case yet.
