Fair Game - S4.E8

Susanna Temple Richards (Played by Jenny Agutter) is having an affair with a local man. Her husband is often seen drinking, so Susanna puts sleeping pills in his whisky to prevent him joining her on the hunt the next day. But he turns up anyway and takes a fall whilst riding, hits his head and dies. There is an enquiry and high levels of sleeping pills are found in his blood stream. Susanna is arrested. (‘The Laid Plans' in series 6 carries on from this) Archie Cutter has died and Claude asks Nick if he can look after his poultry and he agrees. But later Blaketon tells Nick, Archie was a notorious cock fighter.
