Balance is a fragile thing, moments of calm are fleeting. Commissioner Frank Charcot, starting the investigation into the murder, did not even suspect that it would be nothing less than the survival of humanity. And it all starts relatively harmlessly: dead swans are found in a nature reserve in northern France, and several people fall ill with the flu in Paris. However, this is not an ordinary autumn outbreak of the disease; the biological safety service of the Pasteur Institute claims that we are talking about a completely new, moreover, artificially bred variety of the virus. Forensic experts from 36 Quai Orfevre are knocked off their feet. An epidemic is about to sweep the planet, but it is completely unclear whose diabolical plan is behind the dead birds and the chain of strange murders. One thing is clear: the countdown has already started, and there are days, hours, minutes left to solve the riddle... For the first time in Russian! A new novel from the master of the action-packed genre.
