Grace Dent tells the story of Jean, 73, who's being harassed by her 80 year old estranged husband, George. After over 40 arrests, a judge must decide whether George's actions are the result of dementia.

Jean and George finally split up in early 2015 after nine years of unhappy marriage. But for George, that wasn't the end of their relationship. For months, George has been harassing Jean: writing her love letters, verbally abusing her and coming to her flat trying to gain entry. Jean now feels like a prisoner in her own home, scared to go out alone.

Despite over 40 arrests, George won't keep away. As the day of George's court appearance approaches, a judge must weigh up whether George's actions are deliberate or if they stem from dementia.
