The Closers (2005)

Restless after three years of early retirement, investigator Harry Bosch has returned to the LAPD to help close cold cases in Michael Connelly's workmanlike thriller, The Closers. Bosch's first assignment: Figure out who shot mixed-race teen Becky Verloren 17 years ago. New DNA technology links the crime to a white-supremacist tow-truck driver, but Bosch doesn't buy the connection. He's more interested in the unnamed boyfriend Becky gushed about in her diary. So begins another one of Connelly's circuitous trips through the streets and subcultures of contemporary Los Angeles. But in the absence of a feral Poet-like serial killer to keep things exciting, this plodding expedition never really takes off.
