City of Fire by Robert Ellis

LAPD detective Lena Gamble is called to investigate the murder of a young woman. Initially, the police believe that her husband is guilty, but it soon becomes evident that there is a serial killer on the loose who they nickname Romeo. The case then hits closer to home for Lena when her brother David's friend is found dead. Could the case have some connection to her brother's own unsolved murder five years ago? In this mystery, Ellis has created a page turner with an interesting main character. His descriptions of Los Angeles and the LAPD and the unfolding of the story are like Michael Connelly's Harry Bosch series.
