Our Beloved Mona, might be M. Jasper, the author. Perhaps she lived in the Hatmouse house. Or maybe in the now empty lot behind Jodi's, where Harvey mopes around sometimes. He does mention losing a patient once.
One stone is old and faded, with no other info available.
One seems to be a dwarf? The stone reveals a great secret, a great power, a great weapon. But how this came to be engraved here, or why a dwarf may be buried in town, we can never know.
And one grave marker sits facing a different direction, revealing nothing.
Grandpa died, and Alex's mother died, but there are no stones for them.
No one ages or becomes sick, so I don't know how anyone ever died.
