who is getting too familiar with Mrs. Van Daan?

Can you give me the chapter or the dates in the diary? I think I know the answer, I just need to make sure.

can you tell me because then I will know in what dates we are in

I really don't know where you are referring to. I know that the criminal keeps hearing her voice and it scares him off. The people in the Annexe fear that he will tell somebody.

Can you explain me the part of the criminal. who is he?

He is just a robber who wants to steal from the house but hears voices from the annexe.
