Stranger at the Door. Victor J. Banis

Roger needed Lenny, or thought he did, but he did not need Zak or Marty, or the way Lenny acted under their influence. And he definitely did not need to have them move in with him. But Roger's needs and wants were no longer on Lenny's mind. He had another agenda: taking Roger for all he was worth. And he didn't particularly care what he had to do to get his hands on the family jewels! A classic novel of gay life.
