The stories “The Music Maker”, “What a Wonderful School” and, of course, the legendary “Monument” are the first things that come to mind for the domestic reader when the name Lloyd Biggle is mentioned. However, in reality, this master of American science fiction is also known as the author of completely different works. Works, among which the most popular is the series about the adventures of Jan Darzek - a private detective of the future, willingly or unwillingly taking on the investigation of the most incredible cases!.. The action takes place in 1988. The galaxy was unexpectedly attacked from the Large Magellanic Cloud. She is engulfed by Darkness - a form of madness that causes aliens, the indigenous population of any planet, to lose their minds. They raise uprisings against foreigners, expel them, and then famine and decline sets in as interstellar trade patterns are disrupted. Jan Darzek took up the investigation and found that the reasons for the events were hidden in banal lies.
