For maverick LAPD homicide detective Harry Bosch, the body in the drainpipe at Mulholland Dam is more than another anonymous statistic.

It's not much to go on, and Bosch is running out of time, which is why he calls in FBI agent Rachel Walling. What she sees in these photos could blow his case wide open.
