About the Book: Bertie Bradshaw never set out to become a spy. He never imagined traipsing around war-torn London, solving ciphers, practicing surveillance, and searching for a traitor to the Allied forces. When a young woman goes missing, leaving behind a notebook in secret code, Bertie is determined to solve the mystery. With the help of an American girl named Eleanor and his friend David, a Jewish refugee–and, of course, his trusty pup, Little Roo–Bertie must decipher the notebook in time to stop a double agent from spilling the biggest secret of all to the Nazis. From the author of The Great Trouble, this suspenseful WWII adventure reminds us that times of war call for bravery, brains and teamwork from even the most unlikely heroes.
