Better open your case files and start taking some notes, because Unsolved Mysteries is coming back for Volume 3. This fall, the haunting series is bringing you even more mysterious disappearances and baffling — possibly supernatural — phenomena in a set of three weekly episode drops. Settle in for new episodes on Oct. 18, Oct. 25 and Nov. 1, all part of the scariest Netflix & Chills yet. 

The most recent season of the eerie and long-running documentary series tackled circumstances ranging from the mysterious death of a former White House aide to ghost sightings after a tsunami in Japan. And according to a new trailer for the latest installation, “we’ve only began to scratch the surface.”

The show hails from the creators of the original Unsolved Mysteries as well as Stranger Things producer Shawn Levy and his company 21 Laps Entertainment (after all, what’s more unsolved than the Upside Down?). The new season is sure to dive into even darker and deeper mysteries: After all, there’s always something unsolved out there.

Unsolved Mysteries Volume 3 hits Netflix three weeks straight starting  on Oct. 18. Keep an eye out for any paranormal activity.
