"[At HMP Pentonville where the visitors centre was closing] There was, for example, the case of a youngish woman with a large family who visited her husband every fortnight. Each time they came they returned to the centre in a more miserable state. One day they were in tears and the youngest child was sick. The woman said her husband was clearly ill. He had been wild and violent. Each visit he seemed to be getting worse. He was receiving no treatment. The centre called the assistant governor and asked for an urgent inquiry. He acted at once. The man was found to be in appalling state. He was rushed to the medical wing where he was diagnosed as having Huntington's Chorea, an hereditary disease which strikes suddenly in middle age, bringing insanity followed by death. The whole family had been watching, visit by visit, as their father went mad before their eyes. No doubt the prison officers did not like the implied criticism of their negligence. There were many other such incidents, though the centre was as careful as possible not to make the officers feel they were being criticised."
