Springing a Trap

Mysterious signals emanate from the Blushing Cavern. Who is signalling who, and why? Our House needs to know. Your patron recommends you for this kind of work; smart enough to find and triangulate the signal sniffers. Find the location of the signal and boost it so that we can identify which House is using the frequency. We were also told you were tough. Prove it, and you’ll be well rewarded.
