Molly is a mischievous and adorable cocker spaniel trained to be a scent detection dog, specifically, to search for cats. Her owner, the author, runs a private detection business but specializes in finding missing pets. He bills himself as a pet detective. This book tells the story of how Molly was discovered, trained and her many adventures and misadventures finding pets. I can’t say the book is very well written. The editor needed a sharper blue pencil. It is crammed with treacle and puffery, but ultimately, its merit falls on the heart-warming stories of frantic owners being reunited with missing pets. No, not all the stories have a happy ending. I was most impressed with the amount of work that went into acquiring and training Molly and Butcher and the degree of difficulty required in many of these lost pet cases. Experience and knowledge of cat and human behavior were essential in many of the cases. Molly and Butcher are located in England, and there is a lot of British slang and local knowledge, such as London geography and familiarity with British TV shows, which can be charming to some, but at times is a challenge for the American reader. I think any dog or cat lover would enjoy the book if you can overlook a few stylistic peccadilloes.
