Masha Uspenskaya lived a calm life, not even suspecting what a great family she had. An unexpected meeting with aunt Marfa Stepanovna opened her eyes to the real state of the girl's family affairs. Maria realized that she had quite a few close relatives. A trip to her aunt in the village for her birthday promised to introduce the girl to brothers and sisters whom she did not know before. The fun trip turned into a real detective investigation, because ten years ago a murder was committed, and the killer is one of the family members.—Tango Papa
