Mysterious murders, thefts, kidnappings—these kinds of requests come to sixteen-year-old tracker Mishka Mironova. One day she takes a case that looks like an accident: a student ends up under a train in the Moscow subway. The more Mishka learns about the circumstances of the girl’s death, the clearer it becomes that behind it is something bigger and more frightening. In this trilogy, consisting of the books “Dvoitsa,” “Hunting,” and “Sanctuary,” Mishka Mironova’s detective story tackles the most tangled case of her career.
