| Harriet Thatcher|
|First Appearance||Fable III (Mentioned)|
|Last Appearance||Fable III|
Harriet Thatcher was the first, and so far only, female Town Guard in Bowerstone. She is described as not playing by the book, but she got the job done. Her rifle, Dirty Harriet, is a prize at Reaver's Wheel of Misfortune game.
- Harriet's rifle, Dirty Harriet, and the description of her not following the book, make her an obvious reference to the character "Dirty" Harry Callahan from the film series starring Clint Eastwood.
- Her surname, Thatcher, is a reference to Margaret Thatcher, the first and only female Prime Minister, as of yet, of the United Kingdom.
- In Fable II, a letter can be found in the Guild Cave written by Erik. In this letter, he addresses the love of his life as Harriet. Whether or not this is the same Harriet is unknown.
