 In the book, Lazarus does travel back in time and is seduced by his mother, but this takes place years after his own birth.Heinlein did, however, use just such a plot device in the short story "—All You Zombies—", in which a character becomes both of his own parents.A rugged individualist with a distrust of authority, Lazarus drifts from world to world, settling down periodically and leaving when the situation becomes too regimented for his taste-—often just before an angry mob arrives to capture him.
