Sad story. Abusive and loveless marriage, intended murder victim, estranged from her children. Always seemed broken emotionally but kept going. Probably nagging her missing husband in the next life as I type.
Saw that interview and she did seem rather sanguine about the estrangement. You don't know how much of a front that was.
Don't want to speak ill of the dead but she seemed a tad batty during that interview. Probably has a lot to do with all the years being married to the horrendous Lucan and that awful night in 1974 when he murdered the nanny and tried to bump her off.
Honestas non est optimum consilium est: consilium non solum est.
