Also, check if there's any official information from the author about the sequel. From what I recall, Michaelides mentioned on social media about "The Fury" being a sequel where Theo is falsely accused of a new crime. If I can reference that, it would be better. For example, maybe a new case where Theo is the suspect in a murder that he didn't commit, forcing him to uncover the truth while dealing with his guilt from the past.
