France, 1940. Hedda, a bilingual Polish–German woman whose parents have died under Nazi persecution, is recruited by British intelligence. She volunteers for a top-secret mission: to replace an appointee to the German embassy in occupied Paris. Hedda’s breath-taking espionage provides highly classified intelligence to London: information on Operation Sea Lion, Hitler’s invasion of the United Kingdom; atrocities against men and women in Dachau that support US President Roosevelt’s drive to enact Lend-Lease; and advance warning of Operation Barbarossa, the invasion of Russia. Colonel Peter Haden’s epic novel blends lives and love affairs, a page-turning plot, authentic military action and historic detail into a thriller that will have readers hooked.
