In 1992, during the L.A. riots, Harry and his partner investigated the murder of a young Danish journalist, Anneke Jespersen. The investigation was too brief for Harry’s taste, as there were lots of murders during the riots. All they had time to do was gather a spent bullet. Now 20 years later, investigating cold cases, Harry is able to pinpoint the gun that killed her. Determined as always, and flaunting authority as usual, he looks for the “black box” of the case. Just like the black box on a plane, The Black Box in a murder case unlocks the story to Harry. Back then, it was thought Anneke was a victim of the random violence. But Harry uncovers what really happened.
