"Right, out of the zoo..." John thought, stressfully. Finding the entrance on the map (or, rather, exit), he rushed towards the gate, trying to escape the zoo and back to his home's comfort. Reaching the entrance, he found a brick wall with a gate in the middle of it. To his left there was a ticketing booth, empty and abandoned, like the rest of the zoo.

Looking at the gate, John was surprise to see it closed. Trying to open it was futile - it was locked from the other side; locked pretty damn hard, while we're at it. From between the gate's metal bars (which had little space between them), he could see yellow tapes covering the gate.

"I can't exit like a regular human being," John said sarcastically. "And it seems this place is abandoned, too. How am I going to escape, then, sherlock?"
