The Iron Tiger - Jack Higgins

Jack Drummond is an adventurer -- a tough ex-naval pilot who is fed up with too many hot countries and strange cities. He resolves to fly only one more mission.
Dropping off an illegal shipment of arms in Tibet (his last), Drummond is suddenly caught up in a bloody border war. To escape he must fly a boy king and a very beautiful woman to safety.
But someone has burned his plane and destroyed his supplies. To survive he must take on the entire ChiCom army. Against them he has only a plan. A very desperate plan.
