The Men of Silence: Part 1

Harper, the guy you call if you want to get rid of a rival gang, or start a war between the crime families of Palentro, the biggest city on the east coast.
Among the horrors of the city, he's managed to kill his way to the top, and is now regarded as the deadliest man in the country.
His latest contract orders him to kill the only person he fears, a crippled man as old as the city itself.
