“The story of the An-2 plane that disappeared in 2012 and was found a year later, as well as the mysterious signals from it, which turned out to be ordinary interference, gave me the impetus to write this novel, and it would be foolish to deny it. Some early readers noticed that Signals had similarities with my first novel, Justification. It may very well be, since the heroes of both books go, not knowing where, in order to find who knows what. Such a plot provides the best opportunities for a kind of inventory of the country, which, it seems, is not shameful to carry out once every 15 years.” Dmitry Bykov
