But the scene is far from ordinary: no forced entry, a mysterious telescope focused on a random patch of farmland, and an eerie atmosphere surrounding Ravenscroft's life and work.
As the investigation unfolds, Ryland and Mendez encounter a cast of complex characters, each with their own secrets and hidden motives. Dr. Bianca Lorren, Ravenscroft's ambitious prot g , might have had more than just academic disagreements with her mentor.

Coded messages, cryptic symbols, and hidden alliances hint at the dark forces pulling the strings behind the scenes. Ryland's insomnia worsens as he fights to uncover the truth, but his troubled past keeps resurfacing, forcing him to confront painful memories and unresolved grief.
As more bodies are discovered and the stakes rise, Ryland and Mendez must race against time to decipher the twisted connections between the murder and the enigmatic Circle. In a desperate bid to unearth the truth, Ryland finds himself on a perilous path where nothing is as it seems, and every new revelation leads him closer to a chilling conspiracy that threatens not only his life but the very fabric of reality itself.
In a tense standoff, the true mastermind behind Ravenscroft's death is revealed-Dorian Vale, who has been using his power within the Circle of Thirteen to hide dangerous secrets. With the fate of the investigation and Ryland's own mental health hanging in the balance, the detective must decide whether to expose the truth or let the shadows of the past consume him forever.
