The revelation that serial killer Ian Brady may have finally confessed to where the body of Keith Bennett lies buried will be a heartfelt relief for the boy's mother, Winnie Johnson.
But Mrs Johnson's enduring grief may still never be over. Even if Brady's letter describes with some degree of accuracy where the 12-year-old's remains are located, the chances of finding them are likely to be slim.
Keith was murdered by Brady and his partner Myra Hindley in June 1964.
It is thought that he was buried somewhere on Saddleworth Moor, near Manchester, where the bodies of three of their other victims were discovered.
The hilly moor, which is in the northernmost tip of the Peak District national park, is a barren landscape.
Sparsely populated, the grassy moorland is cut with deep valleys and is largely made from millstone grit, a coarse-grained sandstone.
The bleak landscape, while remarkable for its unwelcoming beauty, means finding a burial site after almost 50 years is almost an impossibility.
Numerous efforts have been to locate Keith's remains have been made in the past, by the police, army and even using a US spy satellite, but to no avail.
The letter from Brady - that can only be opened once he has died - will bring some hope of peace for Mrs Johnson.
But until he dies, her torment and desire for closure may never be satisfied.
