At about the same time, Johnson sent Hindley another letter, again pleading with her to assist the police in finding the body of her son Keith. In the letter, Johnson was sympathetic to Hindley over the criticism surrounding her first visit. Hindley, who had not replied to the first letter, responded by thanking Johnson for both letters, explaining that her decision not to reply to the first resulted from the negative publicity that surrounded it. She claimed that, had Johnson written to her fourteen years earlier, she would have confessed and helped the police. She also paid tribute to DCS Topping, and thanked Johnson for her sincerity. Hindley made her second visit to the moor in March 1987. This time, the level of security surrounding her visit was considerably higher. She stayed overnight in Manchester, at the flat of the police chief in charge of GMP training at Sedgley Park, Prestwich, and visited the moor twice. Hindley confirmed to police that the two areas in which they were concentrating their search—Hollin Brown Knoll and Hoe Grain—were correct, although she was unable to locate either of the graves. She did, though, later remember that as Reade was being buried she had been sitting next to her on a patch of grass and could see the rocks of Hollin Brown Knoll silhouetted against the night sky.
