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 healthy and warned humanity against a terrible catastrophe. Maroussia - a girl of 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 “following” they will come across good people and not very well, strange events and incomprehensible accidents will occur. Together with Grisha, they will establish the truth - they killed an ufologist, and not alien aliens at all...
