The museum curator claimed a masked intruder tied him to a chair, ransacked the display cases, and fled through the north window. Detective Vance inspected the room: the chair was facing south, yet the curator's hair was neatly combed forward, his wristwatch was dry despite a rainstorm outside, and the dust on the windowsill was completely undisturbed. Which single detail disproves the robbery?
The undisturbed dust on the windowsill.
If someone fled through the window, their body or clothes would have wiped away the layer of dust accumulated on the sill.
