The secret file of the mysterious death was registered against an unknown person

In our history, there are a thousand unanswered questions, and in our reality, there are a thousand and one unanswered riddles. This book is an investigation of some of the questions and those mysteries. But it is not a criminal, political, or historical investigation. It is an investigation carried out by someone who carries the questions of the general public, and they become his own concern, from which there is no escape except by thinking about them!
Some may see that they are useless questions, as they are closed mysteries that have fallen away with the passage of time, and the punishment in them is linked to God the One, the All-Powerful, and there is no new call in them at the legal level.
But the author believes that researching people's questions is not a search for a punishment for anyone or to convict anyone in the conventional sense, but rather to ease the public conscience and silence the pain of ambiguity. We are against seeing the action and not knowing the perpetrator, or for the crime to occur and the perpetrator to escape.
Yes...it is important to know the perpetrator, even if the punishment is not meted out!
