Task of Kayin by Joseph Samachson — Read

_From out beyond the second sun he came; a fugitive from a dead and sterile world... seeking solace, friends, a home, on Earth -- a planet of even greater terrors._

The sensation of which he was most conscious was that of loneliness. He was no longer very much afraid, and sometimes he even thought that his enemies back home were no longer hunting for him. But in the midst of these strange creatures he learned that there was one thing worse than open hostility, and that was indifference. They had no more interest in him than they had in each other, and even though their indifference increased his own chances for safety, it was a chilling thing none the less.
