“ How does she do it? She makes it sound like she is so cut up to be giving them this information, and it's all just bumph out of her head. She never told them ANYTHING. I don't think she's given them the right name of any airfield in Britain except Mainsend and Buscot, which of course were where she was stationed. They could have easily checked. It's all so close to truth, and so glib--her aircraft identification is rather good considering what a fuss she makes about it. It makes me think of the first day I met her, giving those directions in German. So cool and crisp, such authority--suddenly she really was a radio operator, a German radio operator, she was so good at faking it. Or when I told her to be Jamie, how she just suddenly turned into Jamie.This confession of hers is rotten with error... ”
