A gripping mystery for confident readers. Perfect for fans of detective stories and anyone who enjoyed SMART by Kim Slater.

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?
