You follow Fritz

You casually walk out of the hall trying to not to make it seem like you're tailing the man of science. once you're out on the street you look around and catch Fritz just as he turns a corner in your peripheral vision. You walk briskly to that intersection and are able to tail him all the way to what looks like an old defunct factory that Fritz enters locking the door behind him. Bingo, you're sure you've found the Laboratory. You note down the nearby by intersection and decide to head back to the Inn to report what you've found to the others.

As you near the inn you notice people around you acting suspiciously. They're not outright panicking but you recognize a kind of intentional casual acting. It reminds you of how people in Chicago slums act when they're aware of mob business going on that they don't want to get dragged into. You're on high alert and maneuver your way carefully to the inn, doing your best to not be seen. You duck through an alleyway and find a place where you can see the entrance of the inn while remaining concealed.

You arrive just in time to see Tony being dragged out of the inn by a half dozen burley German men. He's cursing in Spanish and making his capture as difficult as he can but to no avail. The load him into a truck and drive off.

You follow the truck as best you can and see it pull into the building you believe is the laboratory.
