About doubt

Arthur Greer is a very unlikeable man. He has a criminal record best described as disgraceful; he’s violent; and he has convictions for sexual abuse including one of his own daughters. And it gets worse. Greer has spent the last 25 years in prison for murdering a 14-year-old schoolgirl. Most people would think good riddance to bad rubbish, but as Tara Brown discovers, this is where his story takes a turn. Arthur Greer says he didn’t murder anyone – and there seems to be evidence to suggest that, for once, he might be telling the truth.
