Down & Dirty in Brooklyn — Douglas DiNunzio

Before a Mafia hoodlum jumps off the roof at Bellevue Hospital, he asks private eye Eddie Lombardi to right an old wrong committed by his late brother. Eddie agrees. The task is to find and return a jewel-encrusted crown that came to a church in Brooklyn all the way from the Vatican. Unfortunately, that puts Eddie at odds with a dangerous Mafia underboss who has several incriminating secrets to hide.
