The Treetop Murders

Talented snooker player Oliver Castle and Claire Roberts are a team. Late one night, Claire discovers the naked body of their friend, Julie Stevens, tangled in the upper branches of a tree. Everyone believes Oliver wouldn't hurt a fly, yet the police suspect him, especially following two more murders for which he has opportunity, potential motive and no alibi.
To clear himself, Oliver has to solve the case. Drawing on a skill he does not know he possesses, he does so, only to find he can kill, too.
