The Doctor
by Theodore L. Thomas
A doctor named Gant volunteers to be the first time traveler and ends up stranded in a
time of cave people.
There had been a time long ago when he had thought that these people would be grateful to
him for his work, that he would become known by some such name as The Healer.
