"The Shadow Experts" tells a story that brings together the world of spying and a group of experts whose goal it is to help "just causes." The heroine, a very secretive individual with a European aristocratic cover, founded a network of specialists whose expertise encompasses a vast swath of current scientific knowledge. It ranges from highly technical fields such as nuclear physics or bio-medical research to others, more qualitative, such as psychology, art and criminology. Each of the members of the network is sworn to secrecy and only rarely meets either the heroine or other members. This network is known as "The Shadow Experts." They all have their own known and public activities, allowing them to stay at the leading edge of their specialty.
Here, The Shadow Experts are hired by the Mossad to help trace a deadly virus which seems to have hit a few geographical pockets with, on the surface, no apparent relationship with one another.
Using novel and at times even experimental equipment, the heroine, with the help of colleagues from "The Shadow Experts" and Mossad agents, works to find the source of the virus, the reasons for its introduction in selective geographies and the best approach to contain its spread. The hunt for the source takes her and members of her informal team around the world. In the process, she discovers a parallel network of criminals linked to a large and dangerous organization and at least one, possibly two countries and their secret services. Will the project prevent the catastrophe that is being planned?
