and helps her discover her husband's latest affair, but after she confronts Valerie, David convinces her that the affair is over and he wants another chance. However, he now starts to make attempts on Jean's life - firstly trying to push her down the open lift shaft in the house, but Patrick quickly closes the safety gate. Next David dissolves an overdose of sleeping pills in her glass of hot milk - but Patrick intervenes again, causing a loud alarm to ring each time Jean raises the doctored milk to her lips, which makes her realise that there is something wrong with it. David comes in later to see if she is dead yet. Jean consults a solicitor in London about a divorce, but he tells her that her argument that a poltergeist is the only thing preventing David from murdering her 'won't hold water' in court. With Jean in London, David is free to have Valerie spend the night with him. Patrick takes the opportunity to punish them. As they're lying in bed, Patrick locks them in the bedroom and sets Four Winds aflame. When Jean returns later that night, having been driven home by her close friend and confidant Richard Foster (Derek Aylward), she learns that both David and Valerie have perished in the fire, trapped behind the bedroom's barred windows.
