On 10th March 1980, Jean Harris, headmistress of an exclusive East Coast girls school, drove to the house of her lover, Dr Herman Tarnower, author of the best selling ‘Scarsdale Diet’, and shot him dead. She had been aware that he wanted to end their relationship, and claimed that his shooting had been an accident while she was trying to persuade him to kill her. The jury was unconvinced and she was found guilty and sentenced to life imprisonment.
