Saving the Queen — William F. Buckley Jr.

America's vital military secrets are slipping through the Queen's private chambers. The CIA needs an agent suave, audacious and dashing enough to infiltrate Windsor Palace, slip into the queenly quarters, and plug the leak. They need Blackford "Blacky" Oakes.

Movie-star handsome, rich, self-assured, an ex-combat pilot fresh out of Yale, Oakes is a man the young Queen Caroline might take into her confidence. Indeed, he's a man Her Royal Personage might take into her bed.
