Guilt by association

A Deputy DA specialising in high-profile cases, Rachel Knight is addicted to her work and loyal to her friends. But when her colleague Jake is found dead in a Los Angeles hotel room next to the body of a teenage male prostitute, Rachel realises she might not know those around her as well as she thinks. The police want to write off Jake's death as murder/suicide. Rachel doesn't believe it's that simple. Warned off the case but determined to track down her friend's killer, the investigation takes her through the city, from its wealthy suburbs to its seamy downtown heart.
