Find A Lever Or Switch In The Dark

Recommended Posts

Hi I am stuck writing a novel. The protagonist is stuck outside a building being chased by the bad guys. He already tried to get into the building during the day but there was no way in. There are no doors windows or anything. My idea was he sees a lever or switch using a uv torch he is carrying but is this scientifically possible? Can anyone think of a better solution? The important thing is they are able to get in because it's night if that makes sense. Any help would be much appreciated. Max

lots of things do glow under UV light. So, sure, why not.

WHY the lever would glow needs some contrivance; weather it's because it was used by someone covered in some fluorescent dust before and they left a hand-print, or contains some of the right impurities in the concrete or stucco or whatever.
