The resounding success of the universally - documented Roman Forum construction project has changed Adam and Tyra's lives for ever but their true voyage of inner discovery is only just beginning. In the wake of that unexpected but monumental enlightenment amid the ruined and deserted backstreets of the Via Claudia, it seems life has resumed a semblance of normality once more. As the leaves begin to fall and the days grow noticeably colder and shorter with the imminent onset of another winter, all appears well in their fine country house where the flickering candle flames and blazing log fires bring warmth and comfort on the chill evenings. Within the convivial atmosphere of one of Tyra's elegant dinner parties, their all-seeing and spiritualist friend, Sophie, announces an impending discovery which will not only give them all cause to reflect upon their pasts again but will also see a return trip to Italy and a lonely, isolated place where, it seems, the hand of man has not moved for an eternity. Within weeks of Sophie's prediction a team of young archaeologists stumble, quite by chance, on something which when unearthed and investigated will not only confound them with its intrigue and mysteries and leave them searching for answers, it will have far-reaching consequences for Adam, Tyra and Sophie, plunging the world of medical science and the occult movement into shock and bewilderment.
