Bloodmoney

You are facing a medical crisis: an expensive operation, twenty-five thousand dollars, and a deadline that is rapidly approaching. Everything seems hopeless. Then you discover Harvey Harvington — a man standing at a roadside stall, offering one dollar per click. The deal seems good. So you hurt him a little. Two dollars. Four. Eight. The more pain you inflict, the more he pays. The only limits are Harvey's life force and your own sanity.
