With first-hand experience and masterful storytelling skills, former NYPD Capitan Dan Mahoney presents his most thrilling work to date.

NYPD Detective Brian McKenna is back where he belongs--hunting down a mysterious killer who preys upon the city's most forgotten members. At first blush, it seems as if these homeless men have frozen to death on the city streets. But this succession of deaths seems too suspicious for McKenna to ignore.

McKenna makes some curious findings: all the victims were HIV-positive, and all were seen taking their last drink from a bottle of wine given them by a gaunt, black-clad man who goes by the name "Hyde." Who is this sinister figure--and why is he killing harmless men who are already at death's door? A hell-bent McKenna must chace the murderer from the streets of Manhattan through Europe and finally to Costa Rica to uncover the astounding answer.
