Well done!

It’s gruesome as Shor and Aisha remove the clothing from the man to check the entire body. Perhaps you advert your eyes or perhaps you’re looking for clues, but you do find something hidden in a secret pocket on the robes. Inside this pocket is something you’ve seen before: a red and veiny stone. You’d remember that you found a stone similar to this one on the Trog who was eaten by the ooze cube. Wrapped around this stone is a thin sheet of paper that shows what looks like a waterwheel and then an arrow pointing to the space below it, but it otherwise doesn’t show it say anything else. 

If you want you can roll one more time either investigation or medicine to see if there’s any other clues you can find.
