About the book: 2020 / Dina Reznikova followed her usual route - by night train to Moscow, where she worked as a translator during negotiations. Her neighbor turned out to be a dead drunk guy who had scattered things around the compartment. While collecting them, Dina noticed an old document in an incomprehensible language, but at that moment she did not attach any importance to it, because soon her childhood friend Boris Posadsky, who was also heading to the capital, appeared in the compartment. And in the morning, Dina discovered that she had lost her passport, and instead of a hotel she stayed at Boris’s rented apartment. But this turned out to be not the main problem - returning home in the evening, she literally stumbled upon a dead man lying on the landing! It was their overnight companion, but how did he get here and who killed him??..
