Yet when Stephen betrays her, Clara marries Archie, the fiance she discarded four years ago. A friendship but not a love match, this marriage proves a desperate attempt by Clara to rekindle the safety of childhood. However neither party is a child, and their dream sugar house soon begins to dissolve as their fragile marriage proves hopeless.
