Héo, a young architect, moves to Saronida on the eve of Easter 2022. Just before settling in the area, she feels a threat, a bad omen, but pays little attention to it. On her way to her new home, she meets and begins a romantic relationship with the famous Leonidas Magas, a investigative journalist with great success in solving crimes.

Her new life excites her, but something causes her unease. Her old classmate, college friend, and best friend, Zogia, has mysteriously disappeared.

With the help of Leonidas, the police, and friends – or perhaps not so much – she tries to find her. The investigation involves a noir novelist, an actor, two prominent architects, a quirky Mathematics professor, and a retired woman. All of them have something to reveal or hide: guilt, complexes, suppressed feelings, fears, and perhaps a corpse.

The search will last two years, and when it ends, the Saronic Gulf will have darkened and nothing will be the same for any of them.
