The Black Box (Harry Bosch, #16; Harry Bosch Universe, #24)

Harry Bosch first encountered journalist Anneke Jespersen in a dark alleyway. She'd been shot, execution-style, on the night Los Angeles burned in riots and the police protected no one. His investigation was reassigned and the murder was never solved. Now, twenty years later, Bosch comes across a shocking evidence--a gun used in recent crimes is the same one that killed Anneke Jespersen. With this sliver of a lead, Bosch must pry open the case that he has never been able to forget.
The investigation will stretch from the roughest neighborhoods of Los Angeles to distant battlegrounds where Jespersen once covered bloody conflicts. What really brought her to Los Angeles? And in a new age, will Bosch find the "black box," the one piece of evidence that pulls the case together--and makes justice possible at last?
