On 19 December, David Smith, then 38, spent about four hours on the moor helping police identify additional areas to be searched. DCS Topping continued to visit Hindley in prison, along with her solicitor Michael Fisher and her spiritual counsellor, Peter Timms, who had been a prison governor before becoming a Methodist minister. On 10 February 1987 Hindley formally confessed to involvement in all five murders, but this was not made public for more than a month. The tape recording of her statement was over seventeen hours long; Topping described it as a "very well worked out performance in which, I believe, she told me just as much as she wanted me to know, and no more". He added that he "was struck by the fact that Hindley's telling she was never there when the killings took place. She was in the car, over the brow of the hill, in the bathroom and even, in the case of the Evans murder, in the kitchen"; he felt he "had witnessed a great performance rather than a genuine confession".
