On November 10, 2002, Number Five Hargreeves runs out of his home, never to be seen again. Not because he's lost in an apocalyptic future, but because he was murdered. Now, ten years later, newly made cop Diego Hargreeves is desperate to find whoever killed his brother and make them pay. Unfortunately, the case has gone cold with the complete lack of clues as to who killed him. But that all changes when he meets Lila Pitts, a young private investigator looking into a series of murders that may change everything he's ever learned about his brother's death, and may lead him to finding his killer, once and for all.
