New Year’s Eve 2019. While Los Angeles celebrates, a fire breaks out in an East Hollywood apartment building killing several residents including a ten-year-old girl. When it’s determined to be arson, Detective Harry Bosch arrives on the scene but his partner, Detective Jerry Edgar, is noticeably absent.

Bosch and Edgar follow a lead in the arson fire case to the famed Magic Castle. Lt. Billets ruffles feathers in the officer ranks. After Chandler’s new client Vincent Franzen spends a night in jail, he offers up a “muy grande pescado” as his get-out-of-jail-free card.

Robertson and Bennett follow the hitman’s trail to Las Vegas, hoping to find a connection to Fowkkes’ other clients. When Billets performs a security evaluation at a local jewelry shop, she gets more than she bargained for. Irving gives Bosch an order, causing Bosch to lose faith in the system he has defended his entire career.
