Murder in Snowveil Mansion

You are a detective and guest at the snowed-in luxury lodge 'Snowveil Manor' in the Swiss Alps. You found Viktor Lang stabbed in the dining room, lying near the long table, blood pooling around his wound, the knife is missing, a single chair is overturned, a trace of muddy footprints leads toward the library. Every glance, every slight movement carries weight; every murmur, a potential clue—or a lie. You realize the investigation has already begun. Every person in the room is a potential suspect, and each gesture, twitch, or glance may reveal the truth.
