Hal Treherne is a soldier on the brink of a brilliant career. Impatient to see action, his other commitment in life is to his beloved wife, Clara, and when Hal is transferred to Cyprus she and their twin daughters join him. But the island is in the heat of the emergency; the British are defending the colony against Cypriots - schoolboys and armed guerillas alike - battling for union with Greece.
Clara shares Hal's sense of duty and honour; she knows she must settle down, make the best of things, smile. But action changes Hal, and the atrocities he is drawn into take him not only further from Clara but himself, too; a betrayal that is only the first step down a dark path.
