Batman: Secrets & Ghosts by Sam Keith (OOP)

Batman: Secrets follows Batman as he investigates a string of grotesque murders linked to a twisted masked performer whose crimes are staged like macabre theatre, drawing Bruce into a psychological maze of secrets, guilt and repressed memories that forces him to confront how much of his own identity is built on denial, while Batman: Ghosts is a separate, more introspective tale in which Bruce revisits the emotional aftermath of his parents’ death, haunted by memories and visions that blur past and present and explore how grief continues to shape every choice he makes even decades later.

Batman: Secrets & Ghosts by Sam Kieth includes Batman: Secrets issues 1–5 and Batman: Ghosts issues 1–2.
