Despite his passionate love for Ardfalloch, Iain has been driven to let his home and estate to Mr Hetherington Smith, a wealthy London businessman, and his kindly wife (who was, truth be told, happier when they were poor). MacAslan stays on in a cottage by the loch, aided by his devoted keeper Donald and Donald's wife Morag. But he finds himself irresistibly drawn to Linda Medworth and her young son, invited to Ardfalloch by Mrs Hetherington Smith.
