The third adventure in the Isaac Turner Investigates series sees Isaac's summer in Italy go horribly wrong when he becomes embroiled in a heist to clear his grandfather's name. Can Isaac shine a light on the truth in time?

'An ingenious mystery' - A. F. Steadman, author of Skandar and the Unicorn Thief, on THE CLOCKWORK CONSPIRACY

Every summer holiday, Isaac Turner spends three weeks with his grandfather, Ferdinand, at his house in Italy, and this year his best friend Hattie is coming too. Everything points to a fantastic summer, until Ferdinand is arrested for the theft of millions of euros of jewellery.

But Ferdinand hasn't stolen anything - yet.

Drawn into a daring heist during a solar eclipse, Isaac and Hattie must figure out who is telling the truth, and who is using the cover of darkness to deceive them.
