A rare manuscript was stolen from a locked vault. The only clue left behind was a set of muddy boot prints leading directly from the door to the vault, and another set leading from the vault back to the door. The curator insisted no one else had the key. Why did Detective Hayes arrest the curator?
The footprints went in both directions while the vault was supposedly locked from the outside
If the vault was locked and nobody else had the key, the curator must have staged the break-in, but left tracks walking in and out of an un-openable room.
