The Dyad (Dvoitsa)

Sixteen-year-old Mishka Mironova has loved detective books since childhood and has now become a detective herself. Working with the police, she solves complex crimes one after another, but this time she's faced with a challenging investigation: a girl dies under a subway train, her death seemingly an accident... 'The Two' is the first part of a new detective trilogy by Maxim Sonin, author of 'Letters Before Midnight.'
