Split Thread Trivia knowledge solving crimes in fiction

[Gulliver Foyle]

I can't believe that didn't come to mind. I was a big fan of the series back in the day.

Just curious, does anyone know of a crime (real or fictional) that was solved by a nerdy knowledge of Star Trek or comic book trivia?

I'm sure there was an episode where Spock solved a mystery through his encyclopediac knowledge of Star Trek lore.
