The Cop is the second book in award-winning author R.J. Ellory's electrifying ebook-exclusive trilogy, THREE DAYS IN CHICAGOLAND. The testimonies of the sister, the cop and the killer will at last reveal the dreadful truth behind the brutal murder of a young girl in Chicago in 1956.

Had I know then how this case would trouble me, well, maybe I would have done things differently. But hindsight is like that. Looking back, it's always so easy to make the right decision...

My name is Detective Maguire of Chicago PD 9th Precinct Homicide Division. I got a wife, two kids, and a job that some days can suck the life outta you. This case, this pretty kindergarten teacher choked to death on her kitchen floor, should have been open and shut. We did our research, canvassed the neighborhood and finally we got our man. Walked in right off the street, don't you know, and owned up to it. One killer, one confession, one sure-fire conviction. And yet, something just don't sit right for me. And the devil is in the details, or so they say.
