Streaker

The skinny-dipper sightings from the deck of Denny Traeger's commuter ferry fast-track from mere curiosity to a hell-ride.
Is his "Streaker" the spirit of a seahorse-tattooed water taxi driver who drowned seventeen years ago in his teenage estuarine playground on the very day he has a complete memory blank?
His quest to find out pits him against his shrink, Dr Laura Schebel, who is treating him for dissociative amnesia causing sexual dysfunction.
Also against mystery assassins.
And against cold case detective, Cassandra Koh, who suspects him guilty of this and another murder the same night ... of a young boy ... by a paederast.
His struggle for answers triggers the gut-wrenching recall of his missing day and the traumatic event that caused it. Peaking with a confrontation that leaves him fighting for his life.
The setting is Pittwater, the stunning five nautical mile long estuary just 25 kilometres north of Sydney, Australia, fringed on the east and south by northern beach suburbs and on the west by the heavily forested Kuring-Gai Chase National Park. A water playground open to the Pacific Ocean at its northern end, replete with bays, coves and tributaries of great beauty but also offering dark places hiding dark secrets hellish enough to shock a teenage boy into a chronic amnesia that only a cruel plan by his shrink and a ruthless detective can shake free.
