Christmas came once a month in the Open-Unsolved Unit. That was when the lieutenant made her way around the squad room like Santa Claus, parceling out the assignments like presents to the squad’s six detective teams. The cold hits were the lifeblood of the unit. The teams didn’t wait for callouts and fresh kills in Open-Unsolved. They waited for cold hits.
The Open-Unsolved Unit investigated unsolved murders going back fifty years in Los Angeles. There were twelve detectives, a secretary, a squad room supervisor, known as the whip, and the lieutenant. And there were ten thousand cases. The first five detective teams split up the fifty years, each pair taking ten randomly chosen years. Their task was to pull all the unsolved homicide cases from their assigned years out of archives, evaluate them and submit long-stored and forgotten evidence for reanalysis with contemporary technology. All DNA submissions were handled by the new regional lab out at Cal State. When DNA from an old case was matched to an individual whose genetic profile was carried in any of the nation’s DNA databases, it was called a cold hit. The lab put cold hit notices in the mail at the end of every month. They would arrive a day or two later at the Police Administration Building in downtown Los Angeles.
Usually by 8 a.m. that day, the lieutenant would open the door of her private office and enter the squad room. She carried the envelopes in her hand. Each hit sheet was mailed individually in a yellow business envelope. Generally, the envelopes were handed to the same detectives who had submitted the DNA evidence to the lab. But sometimes there were too many cold hits for one team to handle at once. Sometimes detectives were in court or on vacation or on leave. And sometimes the cold hits revealed circumstances that required the utmost finesse and experience. That was where the sixth team came in. Detectives Harry Bosch and David Chu were the sixth team. They were floaters. They handled overflow cases and special investigations.
On Monday morning, October 3, Lieutenant Gail Duvall stepped out of her office and into the squad room, carrying only three yellow envelopes. Harry Bosch almost sighed at the sight of such a paltry return on the squad’s DNA submissions. He knew that with so few envelopes he would not be getting a new case to work.
Bosch had been back in the unit for almost a year following a two-year reassignment to Homicide Special. But coming back for his second tour of duty in Open-Unsolved, he had quickly fallen into the rhythm of the squad. It wasn’t a fly squad. There was no dashing out the door to get to a crime scene. In fact, there were no crime scenes. There were only files and archive boxes. It was primarily an eight-to-four gig with an asterisk, that asterisk meaning that there was more travel than with other detective squads. People who got away with murder, or at least thought they had, tended not to stick around. They moved elsewhere and often the OU detectives had to travel to retrieve them.

Harry Bosch is facing the end of the line. He’s been put on the DROP—Deferred Retirement Option Plan—and given three more years on the job until he’ll be forced to retire from the LAPD. With his swansong looming, he wants cases more fiercely than ever. In one morning, he gets two.
First a cold case from 1989 gets a DNA hit for a rape and murder, pointing to a 29-year-old convicted felon. Was he an 8-year-old killer, or has something gone terribly wrong in the new Regional Crime Lab? The latter possibility could compromise all of the lab’s DNA cases currently in court.
Then Bosch and his partner are called to a crime scene fraught with internal politics. Councilman Irvin Irving’s son jumped—or was pushed—from a window at the Chateau Marmont. Irving, Bosch’s longtime nemesis, has demanded that Harry handle the investigation.
Relentlessly pursuing both cases, Bosch makes two chilling discoveries: an unknown killer operating in the city for as many as three decades, and a political conspiracy that goes back into the dark history of the police department.
The Drop is Michael Connelly’s 15th thriller featuring police detective Harry Bosch—and it’s as twisted as the double helix of a strand of DNA!

I have read all of the Bosch books and The Drop should be...dropped that is.Alot of famous Authors are just cranking out fast junk lately. Don't they have enough money that they can take a bit of time to think of a story line that holds your interest?

This book was a page turner. I haven't read all of the Bosch books but I enjoyed this one.
Reviewer: Roberta G
The Drop by Michael Connelly was a complete disppointment. The author kept dredging up past characters with long descriptions. I understand if this is your first Bosch book, you won't know all the characters personalities, but this went beyond that. It just didn't seem that Connelly's heart was in this book. It read like a debut not a series. Very, very disappointed.
