There has been more than one TV documentary telling this truly awful and unbelievably tragic story and watching the last one, which was from the Police perspective and showed a lot of photos, interviews, film and video of the 'real' people involved, I was simultaneously shocked, sickened, saddened but also fascinated from a human perspective by how strange, drawn out and complex it all turned out to be and, apart from the sadness at the distress and suffering of the victims, how difficult in so many ways it was for those investigating...I won't say too much because some are obviously watching the new drama with the great Tim Spall but I have absolutely no desire to see it and for me it feels voyeuristic and just not quite right as do many 'real life' dramas unfortunately!
