Margaret Mizushima's Killing Trail: A Timber Creek K-9 Mystery is the first book in what promises to be a wonderful series.
Timber Creek, Colorado's K-9 Officer Mattie Cobb and her dog Robo investigate the murder of a local teenager.
The investigation leads to another murder.
Mattie and Robo uncover other crimes in Timber Creek. Mattie learns not to judge people or families too quickly. She begins her friendship with the local vet Cole Walker and his family.
Stalking Ground (reviewed below) is the second book in a series which features animals (dogs, horses, and other creatures). The series shows human relationships, how people relate in small towns, and the way small-town people look out for one another.
Both books tell a surprising amount about how Mattie and Robo were trained for their jobs.
The Timber Creek books are what I would call action-filled police procedurals. For me, the characters and the animals make the story.
My wife read the second book and loved it. She's starting on the first one now.
