Ecumenical conspiracy

... The end of the world is close, the invasion of formidable alien civilizations is coming, and nothing can be changed. No, this is not an advertisement for a new fantastic blockbuster, but part of the popular science film in the planetarium, on which Grisha dragged Marusya on a wonderful summer day.
... the end of the world did not happen, but a corpse was found in the corridor of the planetarium. Ah - the worst! - Maroussia and her childhood friend Grisha just talked with ufologist Yuri Fedorovich. He was alive and well and warned humanity against a terrible catastrophe.
Maroussia - a girl twenty -four years old, a French teacher - lives very boring.
All the entertainment in her life is a craving for detective investigations. Maroussia with Grisha begins to “investigate”! .. On the way of this very "follow -up, they will come across good people and not very well, strange events and incomprehensible accidents will happen. Together with Grisha, they will establish the truth - they killed an ufologist, and not alien aliens at all
