Antonia Forest fans

I think I remember even AF implying that the younger Marlows were wrong in believing that Ann would have told if she'd known what they were doing. Rowan doesn't realize that Giles and Peter might go all the way to France (think I remember that this probably would not have happened without Peter) and so thinks that Ann would have been needlessly worried (not, as it turned out) but probably would not have told. Giles seems to hardly know Ann at all, although she's his sister, and doesn't want to risk it.
