The dog of the title belongs to Christopher's neighbour, and is found by Christopher one morning, having been murdered with a garden fork in its side. Christopher, who is a great admirer of the logical thinking of Sherlock Holmes, decides to investigate and see if he can find out the identity of the killer. His investigations lead him to make some startling discoveries about his own family, and culminate in an exciting adventure on a train.
