   Summary

   When it all feels dark in the detective’s life, the sun shines brighter than ever when a charismatic writer appears in his life. James is a writer, Regulus an inspector. What could ever happen when someone copies the way James kills his characters in his books and uses it to kill someone in real life?

   Or just a marauders AU based on the TV show Castle (2009).
