Keldar follows Tommy to the area. From the roll of tools in his backpack, he draws a tiny hammer, whose proposed use in tooth maintenance is not entirely clear. While tapping his way around the walls, he calls back up the stairs to Vlad Turket.

But there certainly are several aspects of local city governance which could stand some improvement. Maritime property rights, for instance. If you have any clout in the city, as I'm sure a gentleman of your refinement must, you might consider a strongly worded letter or several on the subject."
"Oh dear!" he exclaims suddenly. "Do- do you think that sounded a trifle hollow?" He gives Tommy the shadow of a wink.
When the trick stones are located, Keldar searches for marks that might indicate whether the secret door has been used recently.
