"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.

Leaving behind a coded notebook, Bertie is determined to solve the mystery. With the help of 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"--OCLC.

Now the friends are divided. Tess and Theo have no idea what the photo they found in Greenwood Cemetery means, but Jaime is convinced that they do, and that they've been keeping their own secrets from him. As the city continues to break around them, suddenly solving the greatest mystery of the modern world seems less important than saving their own friendship. The stakes of completing the cipher, however, have never been higher. Darnell Slant, real estate developer and owner of all the Morningstarr buildings, knows that they hold one last secret: a power that even the Morningstarrs themselves never revealed"--Provided by publisher.

But the Old York Cipher still isn't solved. The demolition of 354 W. 73rd Street only revealed the next clue in the greatest mystery of the modern world, and if Tess, Theo, and Jaime want to discover what lies at the end of the puzzle laid into the buildings of New York by its brilliant, enigmatic architects, they will need to press on.
