About the book: 2019 / In the spring of 1912, private detective Yuri Rostovtsev, along with dozens of other citizens of the Russian Empire, boards the transatlantic liner Titanic, sailing to first flight to New York. Going to this city on business, Rostovtsev could not even think that the real deal awaited him not in New York, but on board the Titanic... Who dealt with one of the Russian passengers and why? Why was a socialist-revolutionary militant, an old acquaintance of the detective, on the plane’s crew? How is the famous Tunguska meteorite connected with all this? To find answers to these and other questions, Rostovtsev has exactly four days. Four days to possibly save the Titanic. And to save the world.
