Cambridge professor Tom Wilde has risked his life over three previous thrillers by Rory Clements to spy for and protect his adopted Britain and native United States of America, mainly from the evil Fascists at home and in Germany. Hitler’s Secret takes us two years into the War and he is assigned his deadliest mission yet – to smuggle a package from Germany, which is so incendiary that it is hoped the Third Reich will fall if it is taken to Britain. It’s so secret that Hitler himself is unaware of its existence. Wilde must escape back to Britain with his precious cargo, but he becomes convinced that more will be at stake if he hands it to the Allies’ security forces, even though the secret may help them win the war. The furious pace and level of intrigue are gripping, as always. Clements’ skill puts him at the top of his game and this series in the premier league of historical thrillers.
