Cold rain hammered the old cobblestone alleyway where a pale figure lay perfectly still beneath the flickering yellow street lamp. Detective Vance finally arrived with his tired partner to examine the dark grisly scene that awaited them in the shadows. Thick dark blood pooled around the victim, staining the cold wet stones crimson while the harsh wind howled above them. No personal identification was ever found on the cold corpse, but a strange silver coin rested in his left pocket. The killer had clearly wanted this poor unknown man dead, executing the brutal murder with absolute precision and no mercy. Detective Vance slowly knelt beside the lifeless body, noting the clean incision across the throat that ended this tragic life. He just somehow knew this normally quiet city street would soon become the epicenter of a massive new police investigation. Their first task was to find out who this man was and why someone wanted him completely and utterly destroyed.
