Over the course of ten days, the lives of thirteen-year-old Alex Macintyre and his twin sister Donna will change forever... Alex and Donna live in the seaside town of Holcombe Bay with their father, a reclusive inventor, and their grandmother, a school dinner lady. When the twins set up Eye Spy Investigations in an attempt to earn some money, they become involved in the case of Kiki, a missing lap dog. On the trail of a potential dog-napping gang, they are soon investigating three suspects: a bag lady; a mysterious man in a fur hat; and the bikers who hang out at the Starship Café. But as they pursue their suspects, Alex begins to realise that there is a mystery in his own family involving the mother they never knew. When the twins attempt to help their father market his latest invention, a robot, things go horribly wrong, and they uncover a devastating family secret. As events spiral out of control, can Alex find out the truth about their mother, save Donna from imminent danger, and return Kiki to her rightful owner? Aimed at 9-to-12-year olds, Eye Spy is more than just a straightforward mystery story; it is also a tale of family secrets and lies - and what happens when these are revealed
