When twin brothers Jake and Henry Davies are found dead in their home, the police initially suspect robbery as the elderly gentlemen were known to keep large sums of cash in the house. The autopsy reveals murder however and Sam determines that skin grafts both men have on their arms may have been a crude form of plastic surgery meant to cover tattoos of concentration camp numbers. Thinnking they are now dealing with a hate crime, the police focus on Carl Martin, a known race-hater. What they have however is a case of someone seeking revenge for the atrocities committed long ago.

The continuation of part one, sees Sam delve further into the WW2 atrocities and how it continues to affect those survivors today, as she helps with the investigation about the murder of the twin brothers.

When the naked body of a young woman is found in the snow at a Norwegian ski resort, Sam Ryan is asked to represent the Townsend family whose daughter Ruth disappeared there several weeks before. The autopsy however reveals that it is in fact the body of Louise Hutton who had vanished there some 15 years previously. When Ruth's body is subsequently found, it appears both girls were strangled in a similar fashion. The police focus their enquiries on Ruth's boyfriend and on Henry Hutton, Louise's uncle while Sam seeks the advice of a university colleague and tries to draw a profile of the serial killer.

Sam learns more about the personality type that has now killed 3 girls.

Sam Ryan is under great stress when she learns that she may have a tumor. As a result, she starts to question her judgment when she misses a possible explanation in determining the time of death in the case of Lloyd Dupen's wife, an apparent suicide. She's not convinced however that everything is above board and agrees to undertake a second autopsy at the request of the dead woman's mother. She's also asked by Bishop Craig to perform an autopsy on the remains of Sister Constance, a beatified nun who died forty years ago and is under consideration for canonization. The results of the autopsy will have an impact on the religious order as well as many of those in the community who see the commercial advantages of having a local saint.

Sam's medical condition seems to worsen as rumours fly about her losing her job due to bad judgement.
