In the darkest corners of the city, there is a thriving nightlife where people can let loose and cross the lines of work and play, of pleasure and pain. But now that sanctuary has been breached. A killer has struck and a man is dead. In a world where disguises and discretion are the norm, one admission could unravel a life. No one wants to come forward to say what they saw or what they know--including the woman heading the investigation: Detective Helen Grace. Helen knew the victim. And the victim knew her--better than anyone else. And when the murderer strikes again, Helen must decide how many more lines she's willing to cross to bring in a devious and elusive serial killer."-- Provided by publisher.
