During World War Two the German secret service compiled a book listing all the people they wanted to arrest in Britain if it fell to the Nazis. The top-secret 'Special Search Index GB' contained details of politicians and intellectuals and people who had fled Germany before the war - but it also included relatively ordinary British citizens. Vincent Dowd has been speaking to someone whose father appeared in the book, and to historian Terry Charman who published a facsimile edition of the so-called 'Black Book'.
