Marblestone Mansion, Book 10 — Marti Talbott

Alexandra Sinclair was dead, or so most of the world thought. The duchess, on the other hand, was very much alive. Safely hidden away in Canada, she had all the time in the world to consider her next moves, one of which included a new way to seek her revenge for the way Hannish MacGreagor so cruelly set her aside.With her daughter now married, and her son living in England, a bored Abigail Whitfield felt useless and lonely. Yet, she had something else on her mind. There was a stranger in town that appeared to be watching her, and she didn't like the looks of him one bit.
