- Cathedral Ward, near the first gate that leads from Oedon Chapel.
- Her sign will only appear once you open all the gates in Cathedral Ward.
- Fights against Vicar Amelia.
- Nightmare Church, at the bottom of the staircase.
- Fights against Ludwig, the Accursed.
- Though she can be beckoned to fight Laurence, the First Vicar and Ludwig, it is advised that players should join The League and equip the Impurity rune to get additional help from Valtr and Younger Madaras Twin. Henriett is not as helpful as the latter duo. However, should players not have the Impurity rune, nor desire to, Henriett is the only alternative left.
- Since Eileen the Crow can no longer be beckoned, Henriett is the only female Old Hunter that can be beckoned.
- Henriett isn't involved with either the Choir or the School of Mensis, but her enemies are Laurence, the First Vicar and Vicar Amelia nonetheless. Both are the highest ranking members of the Healing Church. Perhaps she, at some point during the hunt, figured out The Church is behind the plague of blood and beast.
- This appears to be further implied, as she wears the Hunter Set, yet her weapons are all Church weapons.
