Possible betrayer of Anne Frank revealed in new book

A Dutch author's said that he had a nazi-worshiping aunt who may have been the betrayer of Anne Frank's family:

One of the enduring mysteries of the second World War, the identity of the person who betrayed 15-year-old diarist Anne Frank and her family to the Nazis, has apparently been solved – by a Dutch author who has named his own aunt as the most likely traitor.

In a book published on Wednesday about Dutch resistance heroine Elizabeth “Bep” Voskuijl, her son, Joop van Wijk, reveals new evidence that his aunt, Nelly Voskuijl, was a Nazi collaborator from the age of 19 until she was 23 – and is now the prime suspect for having divulged the Franks’s hiding place.

If he's right and his aunt was the traitor, she should burn to a crisp in hell.
