Brown's Requiem by James Ellroy

Set in the gritty underworld of Los Angeles, the story follows Fritz Brown, a disgraced former LAPD officer turned private investigator, as he navigates a labyrinth of deceit, corruption, and betrayal. Hired by a peculiar caddy to investigate his sister's relationship with a wealthy older man, Brown finds himself entangled in a web of crime that stretches far beyond his initial assignment. As he delves deeper, he uncovers a sinister plot involving arson, murder, and a haunting past that threatens to consume him. The narrative is a dark exploration of obsession and redemption, painted against the backdrop of a city where morality is as elusive as justice.
