"Chicago P.I. Michael Kelly is hired by his former partner to help solve an eight-year-old rape-and-battery case, a case it turns out his old friend was once ordered to forget. When his friend turns up dead, Kelly turns to some of his savviest colleagues for help: 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 files, Kelly will have to face the mob, a serial killer, his own double-crossing friends and the mean streets of the city he loves."--
