Paranormal Investigator accepted Islam - Revert story

My son was depressed, used to drink and gambling, he really had no purpose in life. He became a muslim and he stopped drinking and gambling.
What could've had made such an impact on our son, what is it about Islam that can change a person from such a negative to such a positive?
If you ask my wife, what has Islam given to you - she will say, Islam has given me my son back.
As an investigative journalist I was investigating a case which involved a family that has been plagued by something they couldn't see.
For the first time in decades, I was facing a case I couldn't understand. I happened to be talking to a muslim friend and mentioned this case.
He asked me if I have a copy of the Qur'an and asked me to read a particular chapter, Surat Al-Jinn.
As I was reading it, I realized this particular entity is responsible for a lot of the paranormal activities, inexplicable events we see in this world.
The surat also explains perfectly what was happening in this particular case. And I realized that for 1,500 years people have been researching about supernatural, paranormal, all the time the answer we were looking is in the Qur'an from the beginning.
