Training a dog to track a zombie is like training a cadaver dog or a bomb dog. It takes patience, trust, and the right dog-and-handler team. And to not be afraid of zombies. When Angie Graves is approached with the idea of training a dog to track zombies, she thinks this is a bad idea. She has worked all kinds of dogs, including cadaver. But she needs a different dog for this line of work, and the only one available is a rescue named Murder. The problem is, Murder is nothing like a hero dog. He is scarred emotionally and physically. He is slow to trust, has a mischievous mind, and obsesses over his chicken toy. But if he and Angie can learn to work together, they may be able to solve the riddle of where the zombies come from, and why they are snatching up people.
