The Strongroom Shelves

The bookshop strongroom's sliding shelves is a grid of sliding crates with two squares to spare. The deed strongbox — the case's key evidence — must come out through the gap at the bottom centre, but the tray is packed. Slide one crate at a time. A crate moves one square at a time. The strongbox can reach the exit in 21 slides, and no one can do it in fewer.
