Unsettling thoughts occurred as I reached the end of Hit 'Em Hard, the story of Jack Spot, King of the Underworld. All the unwelcome detail of the razor slashes he inflicted on his victims' buttocks (they can't sit down for weeks or the stitches open) and the stabbings and beatings he doled out or ordered over three decades to the end of the 1950s, called to mind not history, but everyday life now.
