The Dark Hours is the 36th novel by American crime author Michael Connelly, and the twenty-third novel featuring Los Angeles Police Department detective Harry Bosch.
The book was published by Little, Brown and Company in 2021.
Publishers Weekly called it a "masterpiece", writing that Connelly "avoids polemics while exploring such issues as internal disaffection among the police (including Ballard's ambivalence about her career), misogyny and domestic violence, and the political divide that resulted in the January 6 insurrection at the Capitol.
"[1] Richard Klinzman of The Florida Times-Union wrote that it "must be tough to continue a long-running career of crime novels the way Connelly does and to never allow the bar to be lowered but he continues to do a masterful job.
"[2] Kirkus Reviews wrote that "no one who follows Ballard and Bosch to the end will be disappointed.
