Solve today's murder
Four rules, one guilty party
One per row & column
Place every suspect so no two share a row or column — the sudoku heart of the puzzle.
Follow the clues
"Beside" means next door and walls block it; furniture blocks a cell; rugs are floor. Cross out the impossible.
Find the room
When every clue fits, one layout remains — and whoever shares the victim's room did it.
