Hello all I've posted only a couple of times here before but I've been following. I always thought that the phone conversation saying he couldn't come was when he called back later and he was told not to come because by then William was missing. If he was missing it wouldn't be unreasonable for williams mum to answer the phone as they might have thought it was someone calling to say they had found him. I think as some of you do that he's turned up unannounced grabbed William then later called again to cover his tracks and was told he couldn't come.
