The Wall — Jo A. Hiestand

When a young art student is murdered, the sister of the accused simply cannot believe her brother is responsible. Worse than that, he dies of a heart attack, provoked--she claims--by a vigilante group and the local shock jock. Ex-police detective Michael McLaren investigates the year-old cold case and soon becomes the victim of a series of driving assaults. Perhaps just as bad, he encounters Charlie Harvester, his nemesis from his days in the Force. A coincidence, or is Harvester somehow wrapped up in the murder? As McLaren discovers the meaning of the brooch, he slowly untangles the web surrounding Amy's death, and barely escapes his own planned murder.
