His name was Heidel von Hymack. Some kissed his hand and worshipped as he passed by; others reviled him, threw stones and tried to destroy him. He was both a walking antibody, a living pool of remedies  Рand at the same time a repository for every foul disease in the Universe.  Often, without meaning to, he killed. Oftener still, with preparation, he cured. There was only one of his kind in the Universe Рand that was why it became dangerous. Many wanted him, needed him to exploit a power game within the Empire. Some wanted him dead, others for a living scientific experiment. The hunt was on, for the man who was both saint and demon.
