The Silent Room

“The Silent Room” is a Murdoku case from the House & Home category: a board of 9×9, 8 suspects and one victim. Read the clues, work out where everybody was standing, and name the suspect who was left alone with the body.

The Board

The floor plan as the case hands it to you: 9×9, rated Hard, with 8 rooms. Every person — 9 in all — takes a row and a column of their own.

The Suspects and Their Clues

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 red hair

  • She was in row 1

Bella — a woman with grey hair and glasses

  • She was on a bed

Cyrus — a man with black hair

  • He was south-west of every TV, in a different room

Dalia — a woman with white hair

  • In her room there was another suspect beside a shelf

Edison — a man with a bald head, a beard and glasses

  • He was north-east of Dalia

Freya — a woman with blond hair

  • She was on a chair

Grant — a man with red hair and a beard

  • He and Anna were neither both inside nor both outside

Hana — a woman with red hair

  • She was south of every suspect who had a bald head

The victim, Viktor, is a man. Nothing else about them is known, and no clue depends on it.

Clues About the Whole Scene

  • Exactly 1 room is empty.
  • Exactly 1 person was on a chair.

How to Start — Without Spoilers

Before anything else, count where each suspect could be if you only read their own clues:

  • Anna: 6 possible tiles
  • Bella: 4 possible tiles
  • Cyrus: 6 possible tiles
  • Dalia: 5 possible tiles
  • Edison: 58 possible tiles
  • Freya: 5 possible tiles
  • Grant: 58 possible tiles
  • Hana: 58 possible tiles

The first deductions after that, in the order the solver finds them:

  1. Edison is north-east of Dalia – impossible cells removed.
  2. Hana is south of someone with a matching trait – impossible cells removed.
  3. Anna: only row 1 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.
