Tom Pascoe, his partner Sam and an ex detective inspector and his wife stumble across a brutal ritual murder near to their holiday center in the south of France. Intrigued by the fact that the victim was a young British student and unconvinced by the description of the act as 'suicide' by the local police, the unlikely quartet investigate for themselves. What they discover as they retrace the victim's footsteps leads them inexorably into ancient customs and civilizations unknown to Man and to incredible riches. It also makes them targets for government agencies who don't want the truth to be known. Pentagon Five is an adventure story with esoteric roots. The characters are fictional; the plot is semi-fictional but many of the events and references are all too real. As to the denouement, that is still to come.
