The voice of the night

No one could understand why Collin and Roy were best friends. Colin was so shy; Roy was so popular. Colin was nervous around girls; Roy was a ladies' man. Colin was fascinated by Roy; and Roy was fascinated by death. Then one day Roy asked his timid friend: "You ever killed anything?" And from that moment on, the two were bound together in a game too terrifying to imagine..... and too irresistible to stop.
