The Coolum economy relies on tourists swarming in to see the rare Cuckoo-Shrike. But there is a cat on the loose, and it's killing Coolum's drawcard. The dead birds have a distinctive signature — a laceration diagonally across their chests. Gregor has seen this before: done by Napoleon, a killer cat from his past. And now he's back from the dead!
A hot, naked Scandinavian named Lola fetches up on Coolum beach, and causes quite a stir. Banks thinks she is a lost backpacker and sets about to help her. Gregor assumes she is a mermaid, with a potent siren song. When Lola takes a liking to Banks, Gregor is fearful for his friend — he's convinced Lola wants to eat Banks for dinner!
