The Second World War Chief of Britain's Secret Intelligence Service, also known as MI6, said Alexander Wilson had 'remarkable gifts as a writer of fiction, and no sense of responsibility in using them!' Wilson's three year career at MI6 ended when the country's spy chiefs decided his creativity got the better of his grasp of reality. His 'secret lives' extended to his private life. Four wives and four families; not necessarily one after the other. The first edition of his biography is the foundation, along with the memoir of his third wife Alison, of the US PBS Masterpiece and UK BBC drama series 'Mrs Wilson' produced by and starring his award-winning granddaughter Ruth Wilson. In this Second Edition, Tim Crook unravels many more of the mysteries of this extraordinary story and profiles each of 'Alec' Wilson's four wives: Gladys, Dorothy, Alison and Elizabeth.
