A city that forgets its murder victims is a city lost. This is where we don't forget," Detective Hieronymus "Harry" Bosch is told by his new boss, as he ends a three-year retirement and rejoins the Los Angeles Police Department at the start of The Closers, the 11th installment of Michael Connelly's Edgar-winning series.
