Amazon.com description: Product Description: CIA superspy Blackford Oakes, fresh from his daring exploits at Windsor Castle, has been entrusted with a matter of some delicacy: finding the perfect blue to restore the war-damaged windows of a thirteenth century German chapel. The owner of the chapel, Alex Wintergrin, is not only an old friend, but a charismatic hero who is rising to power in Germany. He is rallying his countrymen toward reunification, an idea that creates panic on both sides of the Iron Curtain.

As the Cold War turns hot, Oakes is thrown into the arms of a beautiful KGB agent--and onto the horns of a dilemma. He must either betray her or pull the switch on his friend.
