Odd Man Out

The Messer Building is located in the heart of downtown Callahan. It's a building of architectural wonder. It's visible from almost anywhere in the downtown area. And its home to the Darketo Sanction, a top secret organization that's housing the largest collection of mad scientists anywhere in the country. Two weeks ago, the security system in the Messr Building tried to kill every single human onsite and nobody knows why. That's why Alex Cheradon is on the case. (Although, to be fair, it's a building filled with a bunch of mad scientists. This one shouldn't be too hard to figure out, right? Right?)
