The Drop by Michael Connelly

    The evaluation detailed a truly horrible and traumatic childhood. Pell was the son of a heroin-addicted mother who dragged the boy with her to dealer dens and shooting galleries, often paying for her drugs by performing sex acts on drug dealers right in front of her son. The child did not attend school with any regularity and had no real home that he could remember. He and his mother moved about constantly, living in hotels and motels and with men who put up with them for short periods of time.
    Bosch keyed in on a long paragraph that described one particular stretch of time when Pell was eight years old. He described for the evaluator an apartment where he lived for what he believed was the longest period of time he’d ever spent under one roof. His mother had hooked up with a man named Johnny who used her for sex and to buy drugs for him. Often, the boy was left in Johnny’s care while his mother went out to sell sex in order to buy drugs. Sometimes she was gone for days and Johnny became angry and frustrated. He alternately left the boy locked in a closet for long periods of time or beat him brutally, often whipping him with a belt. The report noted that Pell still had the scars on his back and buttocks that supported the story. The beatings were horrible enough but the man also took to sexually abusing the boy, forcing him to perform oral sex and threatening him with harsher beatings if he dared tell his mother or anyone else.
    Soon after, that situation ended when his mother moved on from Johnny. But the horrors of Pell’s childhood veered in a new direction when he was thirteen years old and his mother overdosed on a motel bed while he was sleeping right next to her. He was taken into the custody of the Department of Children and Family Services and placed in a series of foster homes. But he never stayed in one place for long, choosing to run away whenever the opportunity presented itself. He told the evaluator that he had been living on his own since he was seventeen. When asked if he had ever held a job, he said the only thing he had ever been paid for was sex with older men.
    It was a gruesome story and Bosch knew that a version of it was shared by many of the denizens of the streets and the prisons, the traumas and depravities of childhood manifesting themselves in adulthood, often in repetitive behavior. It was the mystery Hannah Stone said she investigated on a regular basis.
    Bosch checked the two other PSI reports and found variations of the same story, though some of Pell’s recollections of the dates and ages shifted slightly. Still, it was largely the same story and its repeated nature was either a testament to the laziness of the evaluators or to Pell’s telling the truth. Bosch guessed that it was somewhere in the middle. The evaluators only reported what they had been told or they copied it off a prior report. No effort had been made to confirm Pell’s story or even to find the people who had abused him.
    Bosch took out his notebook and wrote down a summary of the story about the man named Johnny. He was now sure that there had been no screwup in the handling of evidence. In the morning, he and Chu had an appointment at the regional lab and Chu at least would keep it—if only to eventually be able to testify that they had exhaustively investigated all possibilities.
    But Bosch had no doubt that the lab was in the clear. He could feel the trickle of adrenaline dripping into his bloodstream. He knew it would soon become a relentless torrent and he would move with its flow. He believed he now knew who had killed Lily Price.

    I n the morning Bosch called Chu from his car and told him to handle the visit to the crime lab without him.
    “But what are you doing?” his partner asked.
    “I have to go back to Panorama City. I’m checking out a lead.”
    “What lead, Harry?”
    “It involves Pell. I read his file last night and came up with something. I need to check it. I don’t think
