'There's a spy in England. Frankie's letter. Read Frankie's letter.' These were the last words said by a dying man to Anthony Brooke in Kiel in Germany during the height of World War One.

Here, deep within the English countryside, as Anthony uncovers a web of spies, treachery, and terrorists, the war becomes close and very personal.
