Plenty is doing.
"John Cannan [sentenced to life imprisonment for a series of "monstrous crimes" against women, including murder and rape] wore two different faces for the string of women who, either willingly or in mortal dread, entered his life. The first was that of the charmer, a self-proclaimed romantic who went courting with champagne, chocolates and a winning smile. In the fifteen months before the murder of Mrs Shirley Banks, he boasted to police, he had "a hundred one-night stands". His other face was evil: that of a violent, unpredictable man only too ready to use terrified victims to satisfy his perverted sexual appetite. [The trial judge said Cannan was highly intelligent but had an obsession with having sex by force.] [While previously imprisoned for rape, he met a married woman,] a local solicitor with whom he was to have a lengthy affair. Cannan described [the woman], who is married to a barrister...., as "the biggest thing to happen in my life". However, he did not allow it to hamper his other sexual activities."
