2.  At the end of the movie, Mr. Kraler says that the robber reported the Frank’s hiding spot  Who is this robber?

3.  As the period of hiding went on for longer, the hiders became less careful.  Curtains were opened beyond just a crack, rooftop windows inadvertently stayed open, accidental noises became more frequent, and so on.  All in all, the visible evidence showed the world outside that there were people in the building after office hours.  People in the outside world may quite innocently have mentioned this in conversation, which could have been overheard by the wrong people

4.  On a warm summer day, 4 German and Dutch police pulled up to 263 Prinsengracht  Asked Willem van Maaren where the Jews were hiding  Gave the Jews away  Van Maaren was the main suspect for 20 years  Investigated shortly after the war, but nothing was proved

5.  Interviewed twice- in 1948 and in 1963  Van Maaren committed the warehouse thefts of which he was suspected, yet there is no evidence to support betrayal.  Investigation closed in 1964  Willem van Marren dies in 1971

6.  A member of the Dutch Nazi-party(NSB)  Met with Otto Frank in April 1941  According to writer Carol Anne Lee, this is the person who betrayed the Franks

7.  Tleast likely candidate for the role of betrayer.  Her husband Lammert worked in the stockroom on Prinsengracht  she worked as a cleaner there also

8.  The Netherlands Institute for War Documentation (NIOD) reopened their archives in light of two new theories about the betrayal of Anne Frank.  The first, in Melissa Muller’s Anne Frank: the Biography asserted a claim against Lena van Hartog. The second in Carol Ann Lee's The Hidden Life of Otto Frank concluded that Tonny Ahlers was indeed guilty.  As both were supported by circumstantial evidence neither could be substantiated.  NIOD concluded that the identity of the betrayer is still unknown.

9.  To this day, no-one has been able to answer that question with certainty, and the definite answer will probably never be known.
