Leo does his best to keep his whiskers out of other people’s business. He’s perfectly content to spend his days stretched out in the sun, or wandering through his little patch of the Bronx. So when a south side mouse comes to him with a sob story about a pack of hound dogs trying to run her and her friends out of the abandoned church they call home, his first instinct is to walk away. But why would a mouse be desperate enough to call on an alley cat for help? The raccoons on the south side have their paws in the mix, he discovers, and any deal the raccoons are tied up in is guaranteed to get messy. Add in the fact that the dog pack seems to have come out of nowhere, and Leo’s got more questions than answers. Curiosity killed the cat, as the saying goes, but Leo isn’t going to stop digging until he figures out exactly why St. Bart’s has become… Marked Territory!
