Down by the river where the dead men go

"In his third appearance in George Pelecanos's acclaimed series, Nick Stefanos has been spending too much time with bad women and bad booze. Which is why he wakes up one blurry morning on the banks of the Anacostia River, hungover and miserable--and now a witness to a murder. With the help of a partner as straight-arrow as Nick is bent, Nick decides to track down the killer; their investigation leads them through the roughest part of the nation's capital, and into the darkest parts of the human soul."--P.
