2. Recap of Episode 3 of Lord of the Mysteries
Klein tells Captain Dunn about a dream that points to the location of the stolen Antigonus notebook. They find a corpse tied to the case and learn her son, Ray Bieber, may have the book. The Church provides a dangerous puppet artifact 2-049 to track him, though it’s known to control anyone who gets too close.

When they find Bieber, he’s no longer human and has transformed into a monster by the notebook’s power. During the fight, a clown-faced man from the Secret Order appears, showing terrifying abilities and overwhelming the Nighthawks by exploiting the puppet’s range. To survive, Klein enters the mysterious Gray Fog using a ritual.
Klein tricks the clown, shoots him, and secures the notebook. The episode ends with Klein realizing he has fully advanced as a Seer and now holds the power of the Clown Sequence. But a final clue Hornacis leads him to seek answers from Professor Azik, whose shadow hides something far more sinister.

At the same time, even an ordinary birthday party could turn into something dangerous, as Klein’s instincts warn him of hidden threats. With more questions than answers, he’ll have to trust his gut and maybe a little luck as the line between normal life and the supernatural keeps getting thinner.
