Stephen Williams, the Canadian author who has sold 37,000 copies of his book Karla: A Pact With The Devil since it was released five months ago, is suing publisher Pierre Turgeon and his bilingual publishing house, Cantos, claiming that Williams has been paid only a fraction of what he is due from the book’s proceeds. The book in question, which examines the case of a notorious Canadian serial killer, has been exceedingly controversial, and was at one point thought to be in violation of a gag order issued in the case. Turgeon claims that the controversy has hurt sales, and denies that the book has turned a profit.
