"The traitor is you!"

The informer surprises the heroic lieutenant commander. The one who had made it his life's purpose to shed light on the dark, until now, secret of the betrayal of the Navy Movement. Without this, we would not have reached the dead of the Polytechnic, the tragedy of Cyprus, and its repercussions in our days. Dozens of rebellious warships, like the "Velos," would have forced the junta to resign.

Two couples, the pilot and the lieutenant commander. Two men with heart. Two exceptional women, two intersecting guilts. Marina, the Muse of Patras, the "niece" of Seferis and Katsimbalis. And Elli, the Siren of the Navy, who laments: "My love is the love of Medusa!" And two students involved in their second, secret life. Parallel lives in a unique branching of fate.

A poker game of suspense between dictator Papadopoulos and the Navy conspirators. A fateful industrialist and the Israeli son-in-law of Dimitris Ioannidis, the clinic owner, reveal for the first time the unknown root, the personal life, and the psychological profile of the "invisible dictator," beyond the stereotypes of the Metapolitefsi.

Marina's recent letter - a psychological, existential thriller of our time - bridges the distance from the dramatic moments of '73-'74 to today, opens Pandora's Box, and forces the author to uphold his old oath: To reveal the secrets of the great betrayal in 2023, on the fiftieth anniversary of the Navy Movement, with the impartiality of distance and age.

The case takes a new turn in our days. It is permeated by the bitter feeling of the end of a generation.
