Cat-Girls Have Four Ears

The war of all against all ensues, unnoticed. The investigation into the death of a genetically engineered cat-girl leads detectives Burroughs and Roussel into the strange world of the super-rich.  Those rich enough to breed their own cat-girls as party favors are also rich enough to be above the law.  They even have their own private inter-personal wars going.  Burroughs and Roussel find themselves involved in such a war.
Mike Hammer never had this sort of trouble.
