An internal review estimated that the pursuit had cost the public £3 million and that vital scientific information had been missed. Stagg sued the police for damages totalling £1 million following the 14 months he spent in custody. He has co-written and published two books about the case, "Who Really Killed Rachel?" (with novelist David Kessler) and more recently, "Pariah" (with journalist Ted Hynds), the latter being published on the same day as the real culprit's appearance in court to enter a plea.
