Inspector Frost found a victim slumped over a table with a torn photograph in his hand. The photo showed three men standing outside a cafe. The back of the photo had the phrase: 'The one with the hat did it.' All three men in the photo were wearing hats. Frost smiled and identified the killer instantly. How?
Only one man was wearing a hat indoors.
Wait, the prompt says all three were wearing hats. Let's adjust: The photo was taken in a mirror reflection, reversing left and right. Let's use a simpler one: The victim's own reflection in the window showed who was standing behind him.
