There are good cops, there are bad cops...and there is Pufferfish, aka Detective Inspector Franz Heineken.
Pufferfish (Contusus brevicaudus): Body moderately short, pectorals rounded. Slow swimmer. Scavenger in the mud, at home in the murky shallows, where it roots out and feeds on detritusbody able to bloat and even explode under extreme provocation.
A severed head rolls out of the runnish in a crowded Tasmanian caravan park, and the hunt is on for the killers ... and for their victim, a man no-one seems to miss, a man no-one wants to know.
As Pufferfish digs deeper, he runs straight up against mainland law and order ... and the smell of corruption grows.
