   Summary

   On the 9th of November, 2021, Sirius Black disappeared without a trace.
   His disappearance was confirmed a week later. Then, three years had passed, and two people received a mysterious email with an even weirder address.
   One of them ended up in Regulus Black's inbox. A brief message that made a spark of hope settle in his chest.
   ~
   James Potter was sure it was fate. Since he lost his best friend, anything, even a piece of clothing, made him have the illusion that he could solve the case.
   He received the email, too.
   Being a horror nerd in his childhood for sure had to pay off this time.
