Unexplainable experience

This case is very disconcerting, I would like an opinion. What could a mother who has had a normal marriage of more than 14 years with a daughter explain to the authorities or to morals? The wife has been a very correct woman. During a change of city, they met a couple who were equally young and with a daughter too. A normal friendship began and each one shared more. The husband of the main couple almost always works out of the city and comes home very rarely, but his home is the most important thing for him and he has never neglected it. The wife begins a relationship with her friend's husband and it becomes very intense. to the point of falling in love, this is where the issue comes to understand, he begins to rape the daughter of the bone lover of the first couple, the wife finds out that is another story, then she relates that on one occasion she wrote to the lover that if the girl is in the premises, (an internet business that belongs to the second couple) he answers that yes, it was full, but she realizes that it is not like that and that it was closed, she hurries to get there and when she does she notices that the door is closed and she looks out and no She sees no one knocking but they don't open the door, she sits on a chair outside and the daughter immediately opens it but he is locked in with her, she didn't say anything and asked the daughter if he had told her or if he had touched her or something like that, the daughter said no, she left those like that there was another similar occasion and she realized again that he was telling her lies about whether the place was with clients, it was always closed and she realized again that they were alone and with the door closed she returns and He asks his daughter the same thing until the third time it was that his wife would take them skating and he realizes that he went instead of the woman, he comes back and gets desperate and didn't know what to do why you didn't answer the phone. Then the abuse is revealed and she says that she never knew or suspect that he was doing that. Is it possible that her story is true, that she never realized something or that a tax entity or any person who has a minimum of consciousness can perceive it?
