The Lornea Island Detective Club (Rockpools, #2)

At just 14 years old, Billy Wheatley has already solved two murders – well sort of. So it’s only natural he should open a detective agency on the windswept and lonely Lornea Island.
It’s less likely he should get an actual client – and a partner – but then both are a little crazy, in their own way.
Billy rapidly finds himself investigating the case of a man who disappeared forty years ago in mysterious circumstances. And though it seems like ancient history, his erratic efforts disturb clues that were meant to be long-buried. And the people that buried them. At the same time, Billy’s own hidden past comes back to haunt him in a way he least expects. 
Billy must use his unique combination of charm, youthful optimism and scientific cunning to solve two mysteries, before it’s too late. Because at least one of the people he thinks he can trust is out to kill him.
It’s just not the one he thinks it is.
