What an unusual book. I thought it was going to be a crime/mystery novel - which it is. But it is much more. It’s also a study of the slippery-slide of its narrator into the shadowy world of Alzheimers. We hear Maud’s voice as a young girl in 1947 when her sister goes missing and as it is now: forgetful, confused and worried.
I found this book disturbing and sad. But I gained a lot of insight into what it must be like to suffer from this disease. I hope that when next I talk with a “dotty” older person (to paraphrase Maud) , I will be kind and patient.
