Mickey Spillane 
The Twisted Thing [EPUB ebook] 

This is some household. The kid is a genius, the father a scientist of international repute. Money is a problem. Not a shortage of money, but the opposite: too much. The sort of money that brings the envious and the scheming clustering like flies around offal: nieces, nephews, cousins … a family of mean minds and gross appetites. The staff has its peculiarities, too: the chauffeur is an ex-con; the governess formerly a featured act in strip clubs from New York to Miami; and the secretary has a well-developed taste in other women. Yes, it’s some household — and not all that welcoming of PI Mike Hammer, not when the kid has been kidnapped and everyone’s a suspect.
