The Deep End

“The Deep End” is a Murdoku case from the Pool & Spa category: a board of 7×7, 6 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: 7×7, rated Easy, with 5 rooms. Every person — 7 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.

Alex — a man with brown hair

  • He was beside a slide

Bella — a woman with blond hair

  • She was in the same row as a locker, in the same room

Carol — a woman with red hair

  • She was south-east of a water lily, in the same room

Dylan — a man with grey hair and a beard

  • He was beside a water lily

Elsa — a woman with black hair

  • She was north of every deck chair, in the same room

Floyd — a man with white hair and a beard

  • He was in the same row as a tent, in a different room

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

How to Start — Without Spoilers

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

  • Alex: 3 possible tiles
  • Bella: 2 possible tiles
  • Carol: 2 possible tiles
  • Dylan: 4 possible tiles
  • Elsa: 3 possible tiles
  • Floyd: 2 possible tiles

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

  1. Carol: only row 7 possible – blocked for others.
  2. Elsa: 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.
