The Chicago Way (Michael Kelly Series #1)

Private detective Michael Kelly is hired by his former partner to solve an eight-year old rape and battery case long gone cold. But when the partner turns up dead, Kelly enlists a team of his savviest colleagues to connect the dots between the recent murder and the cold case it revived: a television reporter whose relationship with Kelly is not strictly professional; his best friend from childhood, a forensic DNA expert; and an old ally from the DA's office. To close the case, Kelly will have to face the mob, a serial killer, his own double-crossing friends, and the mean streets of the city he loves.
