From beneath a wartime POW camp near Ely, deep in the Cambridgeshire Fens, a man crawls through an escape tunnel. But he wonââ'¬â"[t emerge until fifty years of peace have passed. When he does, unearthed by archaeologists seeking a Saxon burial tomb, local journalist Philip Dryden knows he has a mystery to solve. First the man appears to have been shot in the head ââ'¬'' and second, he was breaking into the camp not out. The police treat the body as an historical curiosity, but Dryden digs deeper ââ'¬'' and soon unearths a corpse of much more recent originââ'¬Â]
