Just what was going on in the research station up in the mountains in wartime Wales, and what fate befell some of the people who worked there? These questions force David Watkins, into a world of intrigue, duplicity and a conspiracy of silence persisting from those days until now. From the snows of Slovenia to the sun-warmed pastures of Tasmania and back to the chill winds of Wales, his search for a missing relative to complete his family tree forces him to confront some of the murkiest secrets of his beloved country’s darkest hours. A mystery firmly based in science, it never loses its way in the technical aspects of the story it tells. Sub-plots and a plethora of seemingly unrelated events mingle to build a tale of wartime Wales and one Welshman’s search for his roots in it. In the end, Watkins must decide between simply knowing the truth or being able to prove it, whatever the cost. That quest continues almost up to the final page. The story is fiction, but chillingly close to what really happened.
