Where'd all the swimmers go? I'm starting to wonder if the Charterstone pool is some sort of mythical subterranean beast that opens its mouth camouflaged as a swimming pool waiting for its prey to take a dip. The size of the pool adjusts to indicate how hungry it is.
Joe Giella never drew swimmers in the pool because he was aware of this trap, until Olive fell in and was almost eaten. June Brigman still has a lot to learn about Santa Royale, obviously.
