Floor plan of “Treachery in the Knights' Hall”. Letters mark the objects; the key is below. A dashed edge marks a door.
Rooms
Moat (outdoors) — 8 tiles: Water lily
Knights’ Hall — 13 tiles: Chair, Carpet, Suit of armor, Fireplace, Table
Each suspect comes with what the witnesses remember. Read them all before placing anyone — a clue about one person is very often what pins down another.
Anna — a woman with grey hair
She was in a carriage
Bernd — a man with red hair and glasses
He was west of every table, in the same room
Carol — a woman with white hair
She was on a water lily
Dylan — a man with brown hair
He was west of at least one suspect who had glasses
Edison — a man with black hair and a beard
He and Anna were in adjoining rooms
Freya — a woman with brown hair
She was not beside a wooden crate
The victim, Veit, is a man. Nothing else about them is known, and no clue depends on it.
Clues About the Whole Scene
Exactly 2 people were on a chair.
Exactly 2 people were on a carpet.
How Hard It Really Is
Deduction steps from the first clue to the verdict
Before anything else, count where each suspect could be if you only read their own clues:
Anna: 2 possible tiles
Bernd: 3 possible tiles
Carol: 3 possible tiles
Dylan: 35 possible tiles
Edison: 35 possible tiles
Freya: 34 possible tiles
The first deductions after that, in the order the solver finds them:
Dylan is west of someone with a matching trait – impossible cells removed.
Edison is in a room next to Anna – rooms adjoining none of the other one’s possible rooms are removed.
Anna: only row 4 possible – blocked for others.
That is as far as this page goes. From here on it is yours — the in-game hint giver explains each next step if you get stuck, without giving the answer away.
This case has exactly one solution, and it can be reached by forward deduction alone — no guessing.
