From the back cover:
"It is 1871. A prominent New York attorney must go to a private investigator named Harp to find his missing young wife. She has vanished into the teeming underworld of crive and corruption beneath the city's respectable surface-a realm of sin and savagery that Harp knows better than any other man.
But even Harp is shocked at what he discovers when he tumbles over the corpse of a slain prostitute. Only one thing is sure in this labyrinth of lust and lies, where the best people do the worst things, and money can buy anything from a woman's body to a killer's skill. A monstrous murderrer is loose in Manhattan-and to catch him the kid gloves must come off...
When the young wife of a prominent attorney goes missing in 19th-century New York, he hires the police's best investigator Harp to find her. Found in a warehouse sometime later dressed in the missing woman's velvet ball gown is a prostitute who has had her throat cut. Harp must discover who the prostitute is, why she is dressed in a ball gown and where the attorney's wife has gone. Along the way, Harp must talk to the demi-monde of society, criminals and must deal with the police themselves who don't want the case solved.
I really enjoyed this book. It had a very good plot and I give it an A!
