Deadly in New York — Carl Ramm

To save New York City, Hawker must burn down the Village

Outside the cabana, an assassin waits for James Hawker, the country's most dangerous vigilante. Hawker's nationwide crusade against organized crime has led him to the Fister Corporation -- one of the most corrupt businesses on the planet -- and for that, he has been targeted for death. The assassin draws a .38 and screws on a silencer, planning a quick and quiet kill. But it won't be so easy. He bursts into Hawker's room, gun drawn, but Hawker is waiting. The gunman is dead within seconds, and Hawker is safe -- for now.
 
To take revenge on the men who marked him to die, Hawker travels to New York City, where the Fister Corporation backs up their ruthless real estate development with murder. In the tangled streets of Greenwich Village, Hawker will risk his life in the name of justice.
 
Deadly in New York is the 4th book in the Hawker series, but you may enjoy reading the series in any order.
