An old narrow street in Venice... A stranger in a white robe flashed in the crowd... And the lifeless body of the person closest to me - my father... What is this, a bad dream, and I’m about to wake up?.. But the nightmare didn’t even think it would end, it has just begun... It was after my dad’s death that I learned that there was some kind of secret in our family. Trying to solve it, my father died. The key to it is a stack of old letters and a notebook. There is a real hunt for them, the second victim of which was my stepmother. Now the only family I have left is my sister. And I increasingly remember the words spoken by my father before his death: we have an enemy - a certain Max von Lanz. And when my world collapsed, when I only need to think about how to stay alive, my sister and I managed to fall in love... Head over heels, and with the same guy...
