Let's hurry to the rescue!

Exploration Stage: Angela's Park
From: Inspector
Description: A different dimension? I still can't believe that a whole park, not to mention me, could have teleported from jolly old England to here, the City of Shadows. I'd really like to know more about this place. I'm sure this City is full of secrets and mysteries. But I'm afraid there's no time. We need to open the gate and find out what happened in the park. Hurry, Miss Angela could be in mortal danger - I heard gunshots.
Completed: The park is breath-taking: a quiet lake and a lawn, flower beds and shrubs... clear air filled with the scent of flowers. I can see a large house covered in greenery. The harmonious landscape leaves no doubt that this place was created to inspire. Angela sure has good taste. But where is she?
