Short-Order Cop. The 56th Man, #12

Recovering from a seizure, Ari Ciminon (The 56th Man) is enlisted by the Richmond Police Department while still in his hospital bed. In less than two months, four Arabs have been murdered in Greater Richmond. There are no clues, no motives and no apparent connections between the victims. When the families seem reluctant to help find the killer, Detective Yvonne Neumann hires Ari as a special 'cultural consultant'.
It does not take him long to suspect one of the victims was not who he seemed to be; and that he might not be dead. There are plenty of roadblocks, cover-ups, ambushes, red herrings, killers and dolts to deal with, culminating in an assembly of assault teams outside a huge warehouse on Richmond's Southside. Leading the way is Ari, who has come to the conclusion that they are dealing with a gang of human-organ traffickers.
However, the complete answer turns out to be far more peculiar. Human bodies, yes. But what's up with those pufferfishes.?
