Raised by wolves durring WWII

Ok I don't get it. How the hell can anyone be surprised that a book claiming that its author lived with wolves as a child after her parents were taken by the gestapo turns out to be a hoax? The mind boggles. Are we really so in need of believing every tragic story that claims connection to the holocaust that something as obvious as this slips by? Maybe its because we've reached the point where few of the adult survivors are left and the only new stories to be told are from those who were children at the time. I'm not sure but I think PT Barnum continues to stand athwart history pointing and laughing.
