Shallow end
(Book)

English teacher, mother, wife, and convicted child predator Jane Thompson has made parole and she has a plan. She begins her life in the shadows while she bides her time. One month later, the bludgeoned body of the student she was found guilty of corrupting four years earlier is found on the shores of Lake Ontario. Officers Stonechild and Gundersund head up the investigation and Jane Thompson quickly becomes the prime suspect. But knowing guilt and proving it are two entirely different things. Wading through deeply buried secrets to the truth will take Stonechild and the team on a twisted journey into the heart of evil.
