Fire doesn’t just destroy. It divides. When a string of mysterious blazes threatens London’s stables, warehouses, and hidden animal routes, fear spreads faster than smoke. Working animals turn suspicious. Old alliances strain. And beneath the city, something dangerous is being whispered into listening ears. As Sherlock Holmes hunts a human arsonist aboveground, Toby and Whiskers uncover a far more perilous plot below — one designed to turn London’s animals against one another. With the city’s underground on edge and time running out, the secret guardians of Baker Street must stop the flames before panic tears their world apart. Racing across rooftops, tunnels, and the river docks, Toby and Whiskers face betrayal, manipulation, and a threat that can’t be solved with claws alone. Because this time, saving London means keeping its beasts united. Packed with suspense, clever clues, and brave hearts, The Paw Prints of Doom is the fourth thrilling adventure in the Sherlock Holmes’ Pet Detectives series — where loyalty burns brighter than fear.
