This the cover of the 1st ed. of Death Wish. Why does Paul Benjamin shed a blood tear? For his city? For the people he's killed?

From the dust jacket:

Death Wish is the story of a society having a nervous breakdown. It is about something that causes a secret uneasiness far back in the conscious minds of many people. What would happen to a man who is unable to keep to the narrow line that stands between being victim or executioner?

Paramount purchased the rights to both Death Wish and a novel called Relentless. The latter was produced by CBS television in 1977 - a story about an Arizon state trooper--who is also Indian-- that pursues a paramilitary group of robbers (who killed his uncle and have taken a woman hostage) into the mountain and uses his knowledge of the wilderness to track them.
