The scene
Tile Museum · OfficesThree specialists have prepared one parcel each. As the museum closes, they discover that the tile in the display case is missing. A camera confirms it ended up in one of those parcels, but does not show which one.
The individual weighing scale broke down. Fortunately, the courier weighed the parcels in pairs and wrote down the results. The empty boxes have different weights too: it is the contents that matter.
What we know for certain
One of these people put the tile in their own parcel. There were no exchanges or accomplices. Each box contains exactly one object; all weights are exact and measured in grams. The packaging weights include lids and labels.
The three accounts
Elena Ramos
Ceramicist«My parcel seemed the lightest.»
Roc Bernal
Photographer«I only used my usual box.»
Inés Prado
Cataloguer«Do not confuse the weight of the cardboard with the contents.»
