Sam is now firmly established as a professor at the University of London where she is well respected by colleagues and students alike. As an independent pathologist, her reputation goes before her and she is constantly in demand for high-profile prosecution and defense work. Sam's cases involve a series of revenge killings by a former Auschwitz prisoner; the mysterious deaths of teenage girls killed 15 years apart in Norway; a suspicious suicide and a beautiful Nun in a convent by the sea - very different stories, all employing Sam's expertise to the maximum.
