These were equivocal because they could have been caused by the treatments the children had had, and there was nothing to connect her directly to them. He painted a number of portraits of children and scenes depicting children at play, including one of his best known paintings, ‘The Joy of Summer’. Although McTavish successfully appealed against her conviction two years later, it is not hard to imagine that the case struck a chord with Norris as he trudged to his next placement, already disgusted at the prospect of another day in a care home. What appears to have happened in both cases is described by Professor Hutton as “diagnostic suspicion bias”.

This more formal composition of an unknown sitter idealises the beauty and innocence of the young girl with subtle use of colour and tone that creates an almost dream like representation.

Colin Norris, a nurse convicted of four murders and an attempted murder in 2008, is said to have been inspired by McTavish's case. Branded as "extremely arrogant" by Detective Chief Superintendent Chris Gregg, who led the investigation into his crimes, Norris felt untouchable. Over those 19 months, he committed 13 known murders-crimes that included vicious sexual assaults and bizarre stagings of the victims' bodies. Events occurred during the winter period when there is normally an increase in the number of people with respiratory distress and anticipated increase in respiratory arrests.If police, press and prosecutors make decisions like this, what almost happened in Las Vegas would close down every intensive care unit in the country,” he says. He had arrived at this figure erroneously by squaring 1 in 8500, as being the likelihood of a cot death in similar circumstances.
