Hell's Gate

He came out of the dark night with only another man's name...a man who would soon be found floating in a distant river. He was a man without a past, without a future; he had only a bloody mission. His first act was violent murder! He was a man...or was he? Just who was Victor Salsbury? And if he was not a man, then...what was he? And who were the unseen masters, who issue orders only on whim? What were their plans for the world... plans so horrifying that they could change an unfeeling, nonhuman creature into a frightened human! Published in 1970.
