Book of the day: The Drop by Michael Connelly
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 call outs 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 re-analysis 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 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.
Cover blurb
Harry Bosch is facing the end of the line. He’s been put on the DROP - Deferred Retirement Option Plan - and given three years before his retirement is enforced. Seeing the end of the mission coming, he’s anxious for cases. He doesn’t have to wait long. First a cold case gets a DNA hit for a rape and murder which points the finger at a 29-year-old convicted rapist who was only eight at the time of the murder. Then a city councilman’s son is found dead - fallen or pushed from a hotel window - and he insists on Bosch taking the case despite the two men’s history of enmity. The cases are unrelated but they twist around each other like the double helix of a DNA strand. One leads to the discovery of a killer operating in the city for as many as three decades; the other to a deep political conspiracy that reached back into the dark history of the police department.
