Essential rules
Read the clues as positions.
Each person occupies one empty cell. Cells containing a display, statue, painting, information desk, or plant cannot hold a suspect.

"Beside" or "next to" means directly above, below, left, or right in the same room.
PAINTINGS
Memorize the paintings and artists shown before the puzzle starts. Some clues name a painting or its artist, such as "beside the Mona Lisa," instead of showing its picture.
Step by step
One clue unlocks
the next.
Follow each certain placement to see how one clue unlocks the next.
01
Brenda: “I was with Iris in the Ticket Desk.”
Iris: “I was sitting on a chair.”
Fiona: “I was in the top or bottom row, in the second column.”
Read the clues
Each suspect statement narrows the cells where that person could still be.
02
Mark possible cells
Use notes first. When only one logical cell remains, make the final placement.
Place Iris
Only C2 fits both clues. Mark Iris and eliminate the rest of her row and column.
Place Brenda
Brenda must be at D1. Another certain position sharpens the remaining choices.
Place Fiona
With row 1 occupied, Fiona’s only possible position is B4.
CASE SOLVEDFiona is the thief.
Reveal the thief
The Mona Lisa goes at A3. Fiona is alone with it—case solved.
