Firstly, I think it's disgraceful that Sheila and the twins weren't given any help from Social Services or the medical team she was under..... but so many youngsters have suffered this way! What I can't believe either is Sheila's friends, also JB, CC, and BW spoke of Sheila's vacant behaviour and attitude etc Yet the Doctor's didn't see it, unbelievable! Obviously the family had desperately needed help!
Regarding CC's letter, I believe I'm right in saying this letter was never sent to NB. Therefore the family were not aware of CC's comments at the time of the murders. I agree CC did write it, and rightly so, perhaps after his mother had told him of her phone call with JB and JB's concern that the twins could be fostered, CC decided to take matters into his own hands regarding the twins welfare, but the twins began living with him full time soon after owing to SC's breakdown, so the letter wasn't sent. So why then would the family be discussing fostering of the twins on the night of the murders, as the problem was already solved regarding the twins. I'm sure JB would also be happy with this as the twins were remaining within the family. It's more likely that the discussion was about NB and JB's suggestion that SC worked part time at Osea Road, ( this was bought up at a meeting of director's on July 18th ) in fact SC told a friend about this offer before the holiday at WHF.
