In 2010 in Surrey, mother-of–two Sally Challen bludgeoned her husband Richard to death as he sat eating lunch at the kitchen table. She covered his body in a pair of old curtains, a note that said 'I love you', and was later arrested at the notorious suicide spot of Beachy Head. No-one at her trial, including her close family and friends, were surprised when the jury found her unanimously guilty of murder.
