Question: To whom did he dedicate his book "Evil Never Rests" to?
Answer: Sgt. Scott and Private Hernandez
Sergeant Harrison Scott had fallen off the wagon and was living on the streets near the beach. Sergeant Scott revealed to Rossi that his alcoholism–and subsequent homelessness–was a result of guilt for having accepted an award that he hadn’t earned. When pressed, Scott told Rossi that, while their platoon was in the fields of Vietnam, a fellow Marine named Hernandez died when he jumped on a land mine to save their lives.
Afterwards, Rossi and Scott presented Hernandez's grandson, also a Marine, with the medal that his grandfather earned long ago. At the end of the episode, Rossi dedicated his most recent book, Evil Never Rests, to Scott and Hernandez, "two men who saved [him] so that [he] could save others."
