i want to welcome keith jeffery, who has come to talk about his new book. professor speed is a professor of british history at queens university in belfast, and he was commissioned, as i said, the british secret intelligence service. the secret intelligence service is the proper name as i understand it, and mi6 is what was a cover name that was adopted at the beginning of the second world war and it's just kind of stock, and i think james bond has done his part in getting it into our american language. the book is a history of the first 40 years, and as in 1949. the secret service feels very strongly that all the activities post 1949 are still too close back in our history that to allow those activities to be accessed by the public would be the compromise agents, compromise the lives of agents. so we are going to this evening have an evening of disguises, invisible ink and forgery, which were the stock and trade of mi6, and one of the members of mi6 he wasn't -- i don't think he was strictly a member but he was a friend of many members was ian fleming. and
