Hope on a Paige (Tales from the Dead Letter Office)

Paige Andrews has led a life that got off track a long time ago, to the point that she doesn't know how she got there and is unsure how to get out. In the meantime, once a week, she allows herself a fantasy and writes a letter to her fake husband who is away on business.

She mails them to a fake address and doesn't give them another thought, until she receives a response.
