Chapter 30: Escape.
"So that's how it is!" Lisa exclaimed when after a fifteen minute long walk through a straight tunnel, mostly leading down, they arrived at the second junction.
The path split three ways and there was a letter written in yellow paint next to each of them. Few minutes ago, when they got to the first junction, the tunnel split in two and neither thought much of it, but clearly there was some kind of labyrinth underground.
Sensing Lee's thoughts in the darkness, Lisa elaborated, "There were confusing schematics in the hotel and I didn't think much of it at the time. But apparently those were diagrams of the tunnel system here. From the looks of it, dear, you've copied the wrong papers."
"Tunnel system?" Watching his own memories, Lee obviously knew what followed, but back then he was torn whether they should leave at this point, "How big was it, at least from what you remember?"
"We're basically at the starting point." Lisa said with a sigh, "My guess is they have been exploring the place for quite a few days."
"Should we drop the whole thing?" Lee wondered.
"I guess ..." Lisa sounded reluctant, "But after few junctions, paths seemed to join at one point before separating in a bunch of new ones again. What would you say if we go there, take a look and leave afterwards? We should have a little bit of time left, right?"
"We have to map the place ourselves though." Lee said, and grabbed a notebook and pen from his backpack, "If it is as you say, we might get lost here."
"Good thing they marked paths beforehand." Lisa's wide grin was evident even in the dark, "At the first junction they were marked with A and B. We took the A one."
