They were talking about Anne Merry Lafitte St Denis -- her name, her likeness to the description of the woman who bought the music box at Thrift Town, painted scenes on it herself or commissioned somewhat else to paint it, and concealed a medieval book of hours within its base. "Is there anyway she could know that a buyer at the art school fundraiser would discover what the music box contained?" Caydance asked.
"When it became apparent how easy it was to remove the diorama from the base, the book was not difficult to find,” Sido responded. “The base is surprisingly large, as if it was meant to be a container. The space below the music mechanism is accessible, as if meant to contain a hidden treasure. But not everyone would see this."
