I was underwhelmed by this. The selection of voices was strangely limited. The focus is British, and that's fine, but ignores the Commonwealth countries (while having plenty of USA testimony) and their contributions. It spends precious few pages on the Holocaust and has a host family member born in 1940 speaking for a kindertransport child (a great number of whom are alive and well). It also erases the British government's role in Turing's death.
