Jasper Debolt Reardon is the main character's name. He works as a personal investigator. He doesn't look into mundane crimes, however. He's a night owl who looks into strange phenomena that happen at night.

It's not easy being a paranormal investigator. When anything out of the ordinary occurs, few individuals are willing to admit it. Even fewer are willing to engage a private investigator. 

 Usually, by the time people get to Jasper's doorstep, things are out of control; like last month, when he had to banish a poltergeist from the new home of a very rich business tycoon. After he sent the haunt on its way, Mr. Money-bags changed his mind about the possibility of ghosts and refused to pay, claiming Jasper was a charlatan who conned his gullible, young wife.

The wife was not only young and gullible-she was also bored and dissatisfied in her marriage. So, in a way, Jasper got him back. 

Anyway, Jasper isn't here because he wants to be. He's here because something is always pulling him back to these stories. Something like a phenomenon called "system".

Psycho killers, the mob, and even black magic. Can he solve all these mysteries and live to collect his payments? 

It's a litRPG story with Occult Detective genre packed with action and supernatural mysteries.
