Meet Garvie Smith. Good-for-nothing scoundrel, genius, and sometime detective. Right in the middle of exams hell -- until now.

A boy from Marsh Academy has been shot, with no clear motive and no clues. Disgraced police detective Raminder Singh is on the case, and he's determined to keep Garvie away.

But Garvie knows he's the only one who has any idea where to look for the answers. Starting with his best friend's girlfriend. And it's going to take more than pointless studying or flunking his tests to stop him getting involved.

Exams. What exams?
