How about The Isaac Quartet by Jerome Charyn?
http://hammerbooks.org/bookcharyn2.html
The haunting enigma of the Quartet is Manfred "Blue Eyes" Coen, adjutant of Isaac Sidel, the fiercest cop on the street. Coen is killed in the middle of a ping-pong match, and though Isaac didn't really set him up, he gave Coen a little shove toward eternity. Isaac's errant daughter, Marilyn the Wild, was in love with Coen, and Sidel couldn't control his jealousy. But he's punished very quickly; the Guzmanns have infected him with a tapeworm, and this tapeworm unravels Isaac's conscience, makes him constantly dream of Coen.
