"Spencer Quinn speaks two languages -- suspense and dog -- fluently." -- Stephen King

Why would anyone break into 19 Gentilly Lane? That's where the Gaux family lives, and everyone knows they have nothing worth stealing. More important, the house is usually guarded by Birdie Gaux's dog, Bowser, a large and handsome fellow with a big set of sharp teeth.Now Birdie is looking worried and Bowser is on the trail of something rotten. Who was behind the break in? Why is a girl with green hair asking odd questions about what happened to Birdie's dad, a policeman who was killed in the line of duty years ago? Worst of all, why is the whole town starting to stink of limeade aftershave and CAT?!? The death of Birdie's father may be a cold case, but Bowser can tell it's heating up fast. Someone is coming after Birdie and her family, and Bowser must be ready to protect them from anything. Even that awful cat.
