An antique dealer claimed a burglar smashed his shop window in the middle of the night and stole a gold pocket watch. Detective Vance examined the broken glass, which was lying entirely on top of the fresh layer of dust on the windowsill. Vance arrested the dealer. Why?
Glass on top of dust
If a window is smashed from the outside, the glass falling inward would land on the dusty sill, but if the dust is undisturbed underneath the glass, the glass was placed there after the dust settled, meaning the window was broken from the inside.
