Il volto di Orfeo

Near Vienna, where the Roman fortress of Sirmium once stood, radioactivity is significantly higher than one would expect. According to the fascinating archaeologist Martha Stein, they are the traces of an atomic explosion that occurred in 180 AD. Martin Mystère and Java, in Austria to investigate the matter, come across the fearsome secret sect of the Teutonic Knights, who kidnaps Martha and forces our two heroes to recover an ancient and powerful stone seal for them. From Cornwall to the Moroccan desert via Paris, Martin and Java's adventure continues turbulently, making us meet the descendants of the Teutons, the nomads of the desert and the Parisian Court of Miracles, revealing how much truth there is in the myth of Orpheus and Eurydice, and showing us the secret identity of the Great Unknown, the unknown and very powerful leader of all the secret societies in the world!
