The Black Prince — Peter Corris

Cliff Hardy is called to investigate the death of a prominent athlete's girlfriend, in his 22nd case 

They called him the Black Prince. Southwestern Uni's top athlete, Clinton seemed to have it all: he was destined for sporting stardom and lucky in love -- then it all went horribly wrong. Now Clinton won't rest until he's avenged his girlfriend's death. He's after the dealer who sold Angie bad steroids and nothing's going to get in his way. Can Cliff Hardy find him before he ends up on a murder charge -- or worse, dead? The trail leads the Sydney PI all the way to an Aboriginal community in Far North Queensland and back to the shadowy world of illegal boxing.
