This psychological mystery introduces David Morgan and Miranda Quin, two maverick and culturally sophisticated Toronto police detectives. When a man is found dead in a garden pond in the wealthy heart of Toronto's Rosedale neighbourhood Morgan is lead into speculations about Japanese ornamental koi fish, and Quin into a chilling sequence of revelations that could destroy her. But the real mystery begins not with the deceased but with a woman who walks onto the crime scene and without emotion declares herself to be the victim's mistress. From that point on everything changes, even the past.
