After a break-in at their London home, Kat Wolfe and her veterinary-surgeon mum decide it’s time to move to the country. Dr Wolfe’s new job in idyllic Bluebell Bay on Dorset’s Jurassic Coast comes with a condition: they have to adopt Tiny, a huge, near-wild Savannah, who resists Kat’s best attempts at cat whispering. When she starts a pet-sitting agency to make pocket money, her troubles escalate. The owner of her first client, an Amazon parrot, vanishes from his fortified, gadget-filled mansion, leaving a half-packed suitcase and a mysterious parcel. The only person who shares Kat’s conviction that he’s the victim of foul play is Harper Lamb, the American daughter of a palaeontology professor. A language and coding whizz, Harper is laid up with two broken legs thanks to her racehorse, the ‘Pocket Rocket’. What starts out as mystery-solving holiday fun quickly turns deadly for Wolfe and Lamb.
