Blockade Billy - Stephen King book description:
William "Blockade Billy" Blakely may have been the greatest baseball player the game has ever seen, but today no one remembers his name.
He was the first - and only - player to have his existence completely removed from the record books. Every effort was made to erase any evidence William Blakely played professional baseball, and with good reason.
Blockade Billy had a secret darker than any pill or injection that might cause a scandal in sports today. His secret was much, much worse.
