SINCLAIR MCKAY is a popular speaker, and is the author of several books about the people and science of Bletchley Park. He has appeared in many documentaries as an expert interviewee.

His research extends far beyond the boundaries of the SinclairMcKayewartime intelligence centres in Britain, which has led him to investigate the stories of men and women around the world who secretly intercepted the codes that were passed on to Bletchley Park.

Sinclair also writes on this and other subjects for several national newspapers.

He is working on a new talk incorporating much of his research into Bletchley Park and the achievements of British codebreakers in World War II.
