Blackford Oakes Mysteries Volume One [EPUB ebook] 
Saving the Queen, Stained Glass, and Who’s On First

Now in one volume—the first three New York Times bestsellers starring a Cold War–era CIA superspy.   Following the rules kept Blackford Oakes alive when he was an air force pilot during World War II, and it kept him in line as a student at Yale. But as a CIA agent, he knows that sometimes rules need to be broken . . .  Saving the Queen: It’s 1952 and Oakes tackles his first assignment in London. He must uncover a spy within Buckingham Palace and protect the young queen from assassination.  Stained Glass: In this National Book Award winner, Oakes must silence a righteous nationalist stirring up trouble in East Germany, because failure to do so could push the United States and the USSR into World War III.  Who’s on First: The Hungarian Uprising of 1956 erupts, leaving Oakes trapped in Budapest. He soon finds himself in a race to stop the Soviets from launching a satellite—before KGB spies put an end to him.
