Sourcebook
Intro
11:40 PM.
Seven people were staying in a remote manor deep in the mountains.
About 20 minutes had passed since a sudden blackout was resolved...
It was then.
Beyond the sight of Guest and Yoon Chaerin in the living room, the sound of something falling was heard from outside the manor.
Soon, a blood-stained knife was discovered amidst the accumulated snow outside the window.
Upon heading upstairs,
a man's body was found in the 2nd-floor study.
They tried to call the police, but the road leading to the manor was completely blocked by heavy snow.
Mobile phones weren't working properly either, leaving no way to contact the outside world.
The people gathered in the living room were looking at each other.
Someone's hands were trembling with an anxious expression, while someone else was silently scanning the faces of others.
The owner of the manor lay dead in the 2nd-floor study.
And now, isolated, there was only one thing to do.
Who, when, and how was he killed?
The culprit must be found.
