In South America they call it Mano Blanco: the Death Squad. In New York City they call it justice. At the stationhouse and on stakeout, in a guarded hospital room and a bloody executioner's chamber, someone is killing criminals--and their pals--in cold blood. Some cops think the killer is Sgt. Joe Ryker. But when the death squad wastes his best friend on the force, Ryker starts dealing out some justice of his own.

Trusting no one, scouring the city from the rat-infested warehouses to the corridors of City Hall, breaking down the blue wall of silence, Ryker is on a one-man war against a hidden enemy--who have already marked him to die.
