Fun read.
This was a more plausable than Da Vinci Code book from the same trope farm. A trope farm I enjoy visiting, this is one of the better products of this mix of thriller with hints of supernatural and that the Nazis were investing things beyond their ilk and beyond their capacity and that there are some remnants that want to revive their experiments.
Jamie Saintclair thought he knew his Anglican Clergyman grandfather but after that man's sudden death he finds a diary and this lands him into a search for hidden treasures. His father served in the Special Air Service during the Second World War and his last mission was to accompany some Nazi's to freedom as part of something similar to Operation Paperclip.
It's a romp of a story with a lot of complicated derring-do and multiple double-crosses and villains. I did like the end.
It pulled me along and kept me reading, even though it stretched my plausability quota a bit occasionally. The relationship needed work but I suspect things may not be too good there anyway.
