When the body of a middle-aged woman is found frozen beside a canal towpath, it looks like a simple case of death by misadventure. But marks on her neck and a carefully-hidden piece of paper point towards foul play. George Hennessey and Somerled Yellich assemble their team, and quickly begin their investigation into this unusual murder. But as the case progresses they discover that the victim, who was originally from Canada, may not have been all she seemed.
Then reports of a mysterious Canadian man who was seen looking for the woman before her death lead Yellich and Ventnor to a small town in the Ontario Province, and to a shocking discovery that changes the whole nature of the case.
