October 20, then the GCHQ will publish its first ever book of puzzles, devised by some of British intelligence’s finest codebreakers and cryptographers. Proceeds from ‘The GCHQ Puzzle Book’ will go to the Heads Together mental health campaign, a partnership between The Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry and a number of charities providing help for people with mental health challenges.
The Duchess of Cambridge writes foreword for puzzle book where she talks about her codebreaker grandmother Valerie Glassborow.

“I have always been immensely proud of my grandmother Valerie Glassborow who worked at Bletchley Park during the Second World War. She and her twin sister, Mary, served with thousands of other young women as part of the great Allied effort to break enemy codes.

They hardly ever talked about their wartime service, but we now know just how important the men and women of Bletchley Park were, as they tackled some of the hardest problems facing the country. In a new century, their successors at GCHQ continue this intellectual tradition.

Like their Bletchley predecessors, they have become well known for valuing and understanding the importance of mental wellbeing. This is so important when dealing with such discretion and the pressure which comes with this.

William, Harry and I are very grateful that this book is supporting our Heads Together campaign. I hope it will not only amuse and challenge readers, but help to promote an open discussion of mental health problems, which can affect anyone, regardless of age or background.

Together, we are aiming to change the national conversation around mental health from stigma and fear to openness and understanding. Those who buy this book and support the Heads Together campaign will be playing a part in helping people get the important mental health care they deserve.”
