Kill as Directed

Dr. Harrison Brown, Healer or Heel?
Competent, respectable practitioner of the time-honored art of medicine. Dr. Harry Brown — failure! Until the day old man Gresham, with his bum ticker, his millions, and his voluptuous young spouse, Karen, became Dr. Brown’s benefactor and major patient. Then it was money, luxury — and Karen.
