Never lend money to strangers! Who would have thought that because of twenty rubles lent to a strange stranger in a night bar in Tuapse, amateur detectives Katya and Yulia would be drawn into the search for real treasures. Just a few minutes after the meeting, the stranger is killed in a dark alley right in front of her friends, but before his death he manages to give Katya half of the map for finding the treasure and hint with an incomprehensible phrase where to look for the second. As it turned out, in addition to her friends, the map was being chased by very dangerous people who had already killed two people. However, the girls are not afraid yet: they have strong and intelligent accomplices. But when the companions find what they were looking for, this is where the real fear begins... Book 4 in the series about Yulia and Katya. The previous version of the novel was published under the title “The End of the World, Greenwich Mean Time”
