Once A Gunman - Hopper D. E.

He was a young student in medical school in Philadelphia with outstanding athletic abilities and extraordinary quickness of eye and hand. This rare ability results in the death of a fellow student in a swordfight. Seriously wounded himself, Immanual Kant Saye goes on the run, all the way to St. Louis. Then, sad events put Saye on a trail of revenge across the West. Along the way, he finds to his dismay that he is far too good at killing ... blade or gun.
