Bosch said he would give her a good head start. He told her he might drink a cup in the cafeteria just because he missed the place. The place, not the coffee.

“Then I guess that gives me a few minutes to go down the hall,” she said.

After she left the office for the restroom Bosch took the page listing the years that were assigned to them and put it into the inside pocket of his jacket. He left 503 and took the elevator down to the third floor. He then walked through the main RHD squad room to the captain’s office.

The captain’s office suite was broken into two rooms. One room was his actual office and the other was called the murder room. It was furnished with a long meeting table where murder investigations were discussed, and its walls on two sides were lined with shelves containing legal books and the city’s murder logs. Every homicide that had occurred in Los Angeles, going back more than one hundred years, had a listing in these leather-bound journals. The routine over the decades was to update the journals every time one of the murders was cleared. It was the easy reference in the department for determining what cases were still open or had been closed.

Bosch ran his finger along the cracked spines of the books. Each one simply said HOMICIDES followed by the listing of the years the book recorded. Several years fit into each of the early books. But by the 1980s there were so many murders committed in the city that each book contained the accounts of only one year. He then noted that the year 1988 was reported in two books, and he suddenly had a very good idea why that year had been assigned to him and Rider as the new members of the Open-Unsolved Unit. The high point for murders in the city would certainly also mean the high point for unsolved cases.

When his finger found the book containing cases from 1972 he pulled the tome out and sat down with it at the table.
