communication establishment

Exploration Stage: Bright Living Room
From: Valerie
Description: Journalists never stop reading, and they apply what they learn to their work. I've read all sorts of detective novels, and criminals are always working together in some way. Find out how the intruder communicated with them.
Completed: A communicator... clever! I knew it, it looks like this house was broken into by the bad guys. I think we're close to figuring out what happened. We just need a few more clues to get a full picture.
