Luke Callaghan

Luke's a tenacious detective. His smiling, gracious demeanor hides a tumultuous history: a grotesque family trauma left him a fragmented child, bouncing between foster homes. Maybe that's why he's drawn to Andy McNally—because he senses that behind her smile is a troubling family secret. Luke blames himself for letting the killer of rookie cop Zoe Martinelli get away. But, Andy has feelings for Officer Sam Swarek, her training officer, which takes Luke out of the way. Is Luke able to compete with Sam for Andy's love? Luke is currently a Canadian Marshall.
