The couple chose to ignore  the letter, which pushed the ‘obsessed’ Williams  over the edge. She attacked businesswoman Ms Hartley with ‘demonic savagery’At the commencement of the made-for-movie murder trial , the jury was told Williams’s obsession with ski instructor, Ian Johnston drove her to murder his partner, Sadie Hartley, 60, at her home in Helmshore, Lancashire, on January 14 this year.
The prosecution said  that on the day of the murder,  Williams arrived at sales job with Crystal ski Holidays,  about noon but soon after went “scuttling” to the toilet. Her boss, sales manager Colin Pye, then sent her home ill during the afternoon. At just after 8pm on the same day, communications director Sadie Hartley received an unexpected knock on the door of her upscale home in Helmshore, Lancashire, while Mr Johnston was abroad in Switzerland. When she answered the door, an assailant armed with a 500,000-volt stun gun pressed it to her head and then launched a frenzied knife attack.
The court heard that Williams, 35, who is accused of of killing her lover’s partner with “demonic savagery” earlier had an affair with another ski instructor, Somapath Sitiwatju,  who is married with two children. The ending to that affair was messy, as well.
