Well I've done it again, I'm reading a book for pleasure and dementia finds me. The book is "The Thirteenth Tale" by Diane Setterfield.
It is not one of the main characters, it is the minor character of The Missus, the housekeeper of Angelfield estate.
It is interesting to read how the slow devastation of dementia in The Missus is paralleled in the slow deterioration of building of Angelfield itself. It is also interesting how, even though The Missus is the primary person responsible for this great estate and the well-being of five or more people, no one in the household cares (?) that their world has become wonky. Their house, meals, and clothing have become irregular and squalid. Not only can The Missus not care for herself, she can no longer run the estate.
Only her long close friendship with Mr Dig keeps her safe at home.
Ms. Setterfield has written a gripping story, and a very good glimpse into the creeping devastation of dementia.
