A little bit of trivia

So for any of you who happened to pick up an exponent this week, you probably skipped to the good stuff, such as the "Ask Time Traveling Sherlock (from the past)" He is like the male version of dear Abby for our school. His most recent inquiry was from an Andy K. and it said:

"Dear Sherlock, I went to Butte for Saint Patrick's Day over spring break, and i somehow woke up in the middle of campus back in Bozeman, without shoes, a shirt or much of my dignity. All I had in my pockets was a quarter, a piece of paper with a number on it, and what I'm guessing was an old man's prosthetic finger. Is there any way to figure out what happened to me that night?"

Now I'm no Sherlock, but there is a certain book from class that this made me think of, how about you? Perhaps this Andy K. could read it find enlightenment.

P.S. if you cant make the connection you should probably drop the class sorry :(
