A hermetic thriller from the bestselling author of «The Day I Disappeared»
A tense survival test in the spirit of «And Then There Were None» and «Squid Game».
A social experiment with a killer who gets out of control.
How easy is it for you to make a choice? Can you, within a minute, decide who to save—and who to doom? Who is the murderer here, and who is merely an accidental bystander? And if the criminal is right nearby—will you be able to figure him out?
Two brutal murders.
Police, together with the renowned profiler Hon Kichzjun, launch a social experiment based on real cases. The organizers assure participants that nothing will threaten them, anonymity is complete, and the law will be followed. And above all, there’s an enormous sum on the line.
Eight masked participants.
They select eight random people who will have to go through two rounds of «games». In black shapeless suits and masks, they are required to conceal their identities and not reveal anything unnecessary about themselves.
One week in a sealed space.
In a secluded building outside the city, cut off from the world, the participants manage the first stage without major problems. But starting from the second week, the atmosphere changes: the tasks become increasingly unsettling, and the overheard conversation of Hon Kichzjun makes them genuinely afraid…
One killer trapped with everyone.
Among them is a murderer who has already managed to take the lives of several people. They have been deliberately brought together to expose the criminal. And the experiment will not end until he is unmasked.
