Ears Peeled

Exploration Stage: Hidden Row
From: Detective
Description: I swear by my badge, buddy, I didn’t want to drag you into this, but I had no choice. Intuition tells me that they’re spying on me. I have a lot of evidence of varying freshness, and also some gifts from the citizens, but I have no idea where that seashell came from! Let’s examine it.
Completed: Hold this seashell to your ear. Do you hear it? There’s no sounds of the ocean - just a small transmitter’s interference. But the contraption itself is too bright to be inconspicuous. Our spy, despite his desire to snoop, couldn’t deny himself its brilliance.
