For a detailed chronicling of the daily-worsening realities of sharing a house with a relative who has Alzheimer's, these diaries could hardly be bettered. As I read them I felt, along with John, affection for the old man diminishing to fury brought on by sheer exhaustion. Hinch's decline starts gently with a bit of absent-minded behaviour, such as pressing the gramophone needle into a record to try to turn up the volume. He starts forgetting names and fretting about small things. He insists on wearing a jersey and tweed jacket in a heatwave. A few months later, he's found shivering in an empty bath.
