In 1959 agents acting for British Intelligence masterminded the famous escape of the Dalai Lama from Tibet. For Paul Chavasse, expert linguist and special agent of the Bureau, it had been a once-in-a-lifetime mission …

But three years later, Whitehall summons him again for a top secret mission against the occupying Chinese forces. Chavasse is the only man who knows about Tibet. Who knows about the evil its oppressors are capable of. Who knows how to bring a vitally important space scientist back to the West alive.

An illegal plane flight through the Himalayas, a dangerous rendezvous with the Tibetan freedom fighters, almost certain confrontation with a trigger-happy army and a vicious captor … Chavasse knew his mission would be difficult and dangerous. No one warned him it would be impossible.
