As a longtime police officer, Colin Butcher left the force to start his own private detective agency, specializing in reuniting people with their missing pets. Despite his hundreds of successes, there were times Colin couldn't find the missing on his own. He needed a partner. Molly is no ordinary deputy, but a black Cocker Spaniel. Trained by the top canine behavioral experts, Molly can find missing cats who are uniquely skilled at eluding humans by detecting a unique scent signature, and she has been wildly successful. Together, they are the Sherlock and Watson of missing pets.
