Surrounded!

Exploration Stage: Manor House Gate
From: Detective
Description: I see you have a machete in your hands. I need it right now! Can you go up to the roof, while I distract the maniticore? It's pitch-dark in City Hall, so you'd better take your flashlight.
Completed: Thanks, I couldn't fight back without you. Last night I found some clues on the Collector's. Went to City Hall to try and find some info on him and was attacked by the Manticore. This creature is a rare visitor - someone didn't want me learning the Collector's secrets.
