A rescue dog meets a retired police detective and they help find lost or stolen animals, in this nonfiction adaptation for youth.

As a veteran of the Royal Navy and longtime police officer, Colin Butcher was no stranger to dangerous situations and challenges. Colin left the force to start his own private detective agency, specializing in helping reunite people with their lost pets. He soon knew he needed a partner.

When Colin first met Molly, his friends doubted that she would be up for the job. While Colin was battle-tested after a long and varied career, Molly was young and inexperienced. Not only that but she had a reputation for bad behavior. But Colin could tell that Molly was unusually charismatic and intelligent. Today, Molly has overcome all the odds to become Colin's invaluable deputy. Together, they are unstoppable--even if Molly still occasionally steals food from people's plates.

Molly is no ordinary deputy, but a black Cocker Spaniel, and this is no ordinary detective agency. Colin and Molly are the man-and-dog team behind The UK Pet Detective Agency, and they are the Sherlock and Watson for finding people's lost pets.

Molly and Colin are partners in crime, well, in investigation! They have a deep connection, but they also help others find the deep connections that have gone lost or missing.
