Bernie Little and Chet are partners in the Little Detective Agency. Chet being a dog handles the biting and smelling part. Chet is  the narrator of this story although like most dogs he does get distracted with squirrels and food smells quite a bit. But Chet and Bernie are a team. In this fourth book in the series they get involved in a missing child case which leads to money laundering and murder. One thing I learned from this book is that if you are a private detective you might want to get a remote starter for your car just in case. I especially like these books because Chet looks just like my dog Rugby.
