Lord Ashfordly's winter pheasant shoot is seriously disrupted when the entire contents of his game larder are stolen. There is an out break of petty thefts on Nick's patch and when he investigates, his enquiries make him believe that an incestuous relationship is the reason behind the thefts. Susan Rawlings, a teenage daughter of Lord Ashfordly's game keeper, is pregnant and steals money from Greengrass to pay for an illegal abortion. Unaware of this, her brother Chris stole the pheasants in order to raise cash for the same purpose. Susan has the abortion, but ends up in hospital. When Kate and Ferrenby find out, they go to see the woman responsible for doing it and warn her of the dangers involved. Chris it turns out is the father of his sister's unborn child.
