might cause Anne to simply not trust hereself. The doors this bit of news opens! The hopes it inspires! I think she probably only trusts herself to respond to what others may say. I do agree with the idea that she doesn't want to "contaminate" any of the news the Crofts may be able to give on the subject. As her history with CW is unknown, she doesn't want to "upset the apple cart" by drawing ANY attention to herself which may arouse suspicion. She doesn't trust herself to initiate any conversation bearing on this.
