From: Buckingham Palace, 13 August, 2014.
Dear Mr. O'Donnell
I have been asked to thank you and all those taking part in the Ninth
World Sudoku and Twenty-Third World Puzzle Championships which are
being held from 10th to 17th August at the Selsdon Park Hotel, Croydon, for
your kind letter containing loyal greetings to The Queen.
Her Majesty was interested to learn that this is the first time these events
have been held in the United Kingdom and appreciates your thoughtfulness in
writing as you did. In return, The Queen sends her good wishes to all
participants for a successful and enjoyable event.
The Chief Clerk to The Queen.
