Here's how it works. You're snooping around and you find one Old Man Herring was at the crime scene on the night of the murder. You can look up his address in the directory...
...and head over there.
From here, you have a few choices. Let's say you do the basic - knock on the door, see if anyone's home, and ask him what he's up to. You do that by opening the envelope in front of the house.
Seems like a prime suspect. From here you could check his alibi by looking up the local cemetery - but if you want to go further here, you can sneak into his house and look for clues. You do this by actually opening up the house itself.
Inside every one of these houses will be physical clues and evidence.
You will be able to search almost any object in the game like this. Say you want to search the boot of his car:
The room will be full of tables, each one a block of town filled with houses and props like this. Every one of these cute little paper props will pop open to reveal filthy, horrifying secrets hidden within. The paper houses, the cardboard graves - they all hide secrets.
You'll sign up to solve a certain mystery with 1-7 of your friends, and spend the time snooping around this town while everyone else is hot on the trail of their own case, At the end, all of these mysteries will explode together in a climactic Denouement where you reveal the answer - or answer wrong, and see the villain get away laughing.
I'll keep updating this blog and the facebook group with more details and snapshots of more of the buildings. I'm planning to put tickets on sale this week or the next.
