Yeh, I can see that this may have descended into a game of tit for tat between two adult women, but exactly when do you think Sheila decided to take her revenge on June and Neville by contacting Christine to ask her specifically to phone her at WHF. We can only speculate about what went on round the supper table and whatever it was going on -or NOT going on- between Colin and Sheila had nothing to do with Christine. Sheila had gone to endless lengths, to keep secret, what turned out to be a fleeting relationship with Christine and as Christine had told her there couldn't be an ongoing relationship it's highly unlikely that she'd have phoned her. Imagine if June or Neville had answered!!!!!
Perhaps you did read something about Christine on red though I doubt it had to do with a phone call Sheila was expecting from her at WHF and you are the only one who's mentioned it here.
Good points, apes.
The conversation around the supper table, that just happened to occur on a night when Bamber happens to leave a loaded weapon out, is another aspect of the case that just doesn't ring true to me. Sounds very constructed and false to me. Much like the story of attempting to shoot rabbits.
