The Nemesis Cell – Brian L. Porter

A group of women gather at a Belgian fertility clinic, where Dr. Margherita Dumas offers a revolutionary, experimental treatment for their infertility problems. A year later, each of the women give birth to healthy baby boys.
Thirty years later, a mysterious killer begins to wipe out the children born as a result of Dumas’ programme. Detective Inspector Harry Houston and his team are assigned to piece together the case and bring the killer to justice.
With time and clues in short supply, can Harry and his team find the link between events of the past and the deaths of the innocent progeny of Clinique Sobel?
