Out of Bounds by Val McDermid is a great thriller. Set largely in Scotland it tracks the intersection of two cases--one very cold, the other very recent. Detective Karen Pirie and the young detective she is mentoring are a perfect pairing of opposites. She is hard-edged, highly capable and dismissive of politics. That can be a dangerous position to take as clashing interests intent on covering up decades of sin threaten to bury her. This is an enthralling read with terrific character development and a truly puzzling case.
