The third book in the irresistible series about the chosen family, high expectations of theft, and what it truly means to be good. Ideal for fans of M.G. Leonard and Anthony Horowitz.

Gabriel is in his third year at Crookhaven School of Thieves. Along with the annual Heist Challenge - this year on Redemption Island - and tough new classes like Marks & Signals, Gabriel and his friends have one more goal: to defeat the Anonymous.

The Anonymous are the worst kinds of criminals - they steal, deceive, and kidnap for their own benefit, instead of doing good for the world. Each member of Gabriel's team has a very personal reason for wanting to defeat the Anonymous - but what can a group of underage students do against the most powerful gang of the underworld?

Fortunately, there might be something hidden in Crookhaven that could help them. But first, they have to find it...

The third book in the 'criminally good' Crookhaven series, the secret school where students learn to make mistakes so that one day they can put the world right.
