Malcolm John Webster (born 18 April 1959) is an Englishman convicted of the murder of his first wife in Scotland in 1994 and the attempted murder of his second wife in New Zealand. Both cases involved staged car crashes and were carried out for the life insurance money. He was diagnosed with narcissistic personality disorder by a consultant forensic clinical psychologist, Dr. Gary Macpherson, who prepared a report prior to his trial. A police profiler labelled him a sociopath. His crimes were portrayed in the three-part ITV miniseries The Widower (2014).
