From New York Times bestseller Spencer Quinn comes book 2 in the laugh-out-loud series about the most epic rivalry of our time...

Arthur the dog vs. Queenie the cat. Queenie the cat has a BIG problem. And for once, it's not the slobbery, overly-excited creature who also lives at Blackberry Hill Inn. Sweet Lady Emsworth, the neighbor's prize cow, has disappeared, meaning no morning cream for Queenie. And when Queenie's not happy, NO ONE is happy... Things aren't looking great for Arthur the dog, either. His beloved humans, twins Harmony and Bro, are distressed about the strange activity in their town. Mysterious hi-tech people are suddenly very interested in nearby Catastrophe Falls, bills are piling up at their mom's inn... and now the twins might be hiding a fugitive?! Arthur is desperate to help but for some reason, no one seems to think he's up to the task. (Could that be because he can't remember what happened more than ten seconds ago? Surely not!) Can Arthur save the day—and become a hero in Queenie's eyes—without making a disastrous splash?
