The rules

  1. Exactly one person in every row and every column.
  2. Nobody stands on solid furniture; chairs, sofas, benches, beds and rugs are fine.
  3. Every statement is true. “Beside” means the square directly next to it; north is up.
  4. The victim was alone in a room with exactly one other person: the killer.
Show the answer and the solution to case #17

The killer was Hugo (the hotel manager) — the only other person in the Shop Floor with Ada. Otto: C6 · Quinn: E5 · Hugo: B1 · Dev: F4 · Felix: D3 · Ada: A2.

How to solve it, step by step

  1. Hugo: “He was beside a plant. There was a wardrobe in his column.” Only one square on the whole plan fits: B1.
  2. Otto: “He was in the Back Yard.” Of the squares that fit, only C6 is still open — the others are in rows or columns already taken.
  3. Quinn: “She was beside a bookshelf.” Of the squares that fit, only E5 is still open — the others are in rows or columns already taken.
  4. Dev: “He was beside a crate. There was a crate in his row.” Of the squares that fit, only F4 is still open — the others are in rows or columns already taken.
  5. Felix: “He was in the Stockroom.” Of the squares that fit, only D3 is still open — the others are in rows or columns already taken.
  6. Ada, the victim, has no statement — but only one square is left in a free row and column: A2, in the Shop Floor.
  7. Everyone is placed. Ada lies in the Shop Floor, and the only other person in there is Hugo. Hugo is the killer.
