What kind of clues/checks can I give my players to realize that a statue in an art auction is actually a petrified person?
I've decided that the reason his parents abandoned him is because they were being hunted by a medusa. He was asleep in a basket; the medusa was coming; they hid him under a bush and led her away, whereupon they both got petrified.
For her part, the medusa's whole gig is that she sells her petrified victims as fine art, in order to support her taste for decadent living. She may show up as an antagonist later.
Clues I've thought of so far:
1) A perception check to recognize the pattern on her tunic as matching one on the blanket Micah was wrapped in, which only he would know, so only he could make the check.
2) Some kind of skill check (Perform? Profession something?) to realize the statue is too perfect to have been carved.
They need some way to figure out that A) the statue is actually a person, and B) she's my PC's mother. I'm just hoping for some more ideas for clues I could add, because letting it all rest on a single Perception check by one PC seems awfully chancy. His perception is not that great.
