When a frozen corpse is discovered amid a Helsinki winter, Detective Superintendent Topias Torikka is brought in to investigate. The dead man is the husband of a beautiful and beguiling young woman, whom Topias suspects knows more than she reveals. However, before long, she also finds herself in peril, and as the case progresses, so too does the body count. Intriguing connections arise, and motives appear, including the usual suspects: love, betrayal and money. Can Topias identify and bring a criminal conspiracy to justice before someone else dies?
