Twinkle, Twinkle, Little Spy hp-6
by Len Deighton
A Russian scientist defects, believing that in the West he will more easily realize his dream of contacting planets in outer space. But British Intelligence and the CIA have more worldly plans for him and move quickly, relentlessly, leaving behind a trail of blood which stretches from the Sahara desert to Manhattan, Paris, Dublin and halfway back across Africa.
