Butler's Note is a written note found in The Brigmore Witches.

The urn will have to stay here, Reggie, until we can return by boat and claim it. The master's key, however, will go with me and – since you are nowhere to be seen – I have little choice but to scale the rocks by the waterfall and make my escape cross country. Leave me out to dry on this one and I'll put a bullet hole in your skull.
