The Queen of Spades

From the publishers blurb: Six murders in a single night! A major city in the Forgotten Realms is rocked by a series of gruesomely bizarre deaths of notable citizens. What mysterious murderer could have slain six people in different corners of the city? Why did the criminal leave a playing card at each scene? Could a high-stakes card game that happened ten years ago explain the goings-on? And, most importantly, is the goddess of misfortune personally involved?
