Joyce Mariner (on the right) and her friend, Hetty, taking a break on the Annexe roof. They worked on codes and cyphers in 'X' Branch which was based in the Annexe. Both were fortunate to escape the bombing with no more than a covering of dust but Hetty was Jewish and her parents sent her to the US after the atrocity and Joyce unfortunately lost touch with her friend.
The YMCA and the King David are both in the background.
