The Black Echo: Michael Connelly

'Bosch stared at the photograph until fatigue and alcohol pulled him down... almost dreamlike. He remembered that last tunnel and he remembered Billy Meadows.'
One Sunday LAPD homicide detective Hieronymus 'Harry' Bosch gets a call-out on his pager. A body has been found in a drainage tunnel off Mulholland Drive, Hollywood. The body looks like yet another OD, but Bosch isn't convinced. The one new puncture wound amidst the scars of old tracks strikes an odd note. And something else: Harry knows him. Billy Meadows was a fellow tunnel rat out in Vietnam, running against the VC and against the fear they used to call the Black Echo. Harry let Meadows down once; he won't do it again.
