There is only one person on this damn planet who believes in me. My little brother. But one day he disappeared. He boarded the train and was never seen again. Two thousand kilometers of railway. The rails run across the entire country. Somewhere out there, my brother got into trouble. And I’m the only one who can help him. I feel that he is alive and that he needs me. And I won’t rest until I find him. Whatever it costs me. Then I didn’t even suspect what I was getting myself into... “Cryptography.” The second novel by Ilya Bushmin.
