Utterly Mad

Griffin:
You break the window, and scream into the store. The noise your heard earlier is noone to be seen. Or heard, for that matter...

It's silent inside. But without the dirty glass, you notice tracks leading through the back door. Human, and dog tracks.

Sammy & Lucy:
You start rowing inland(?) at a steady pace.

Soon you reach the edge of something strange.

There's a thick cloud of smoke ahead, engulfing the canal. Yet the sky is still mostly clear, and the sun is still up. It smells bad, like really bad.
But it doesn't seem dangerous. In fact, the only danger is not seeing that well on the canal.

You note a sign on the side aswell, written resently.
"DARK CANAL"
