Status Updates From The Double Turn

This book has one of the weirdest characters I've ever encountered in fiction. Not weird as in simply unusual, but weird as in bizarre, nonsensical, uncanny. Miss Trimming as a character makes little sense. An overbearing, possibly unhinged, religious fanatic of a housekeeper who runs the house as if it's her own, her master both afraid and devoted to her while she essentially keeps him as if under house arrest.
