There is a hidden treasure in the grand old mansion on Piccadilly Street, in a place called London, but not the real London of English fame. There's also a lot of mystery and a murder that's been unsolved for decades. But it's the treasure that captures Mary's interest. Mary lives in this house along with her family, her Brownie friends and a ghost. When the ghost reveals her secret about the hidden treasure, there's no stopping Mary, her Brownie friends, or her enemies from searching for this treasure. Why the intrigue? Apparently there's a little bit of magic connected to this treasure. And so the adventure begins. Who will find the treasure first?

It's 1967 and Mary's family has moved into a huge Victorian mansion. She loves her gigantic new house, especially her room. But then she begins to meet the house's other residents. Mrs. Murray was murdered in Mary's new house. At first she tries to scare the new residents away, but there seems to be a force connecting the ghost to Mary. Even the stranded Brownies, the little people who live between the walls, feel that connection. When Mary becomes deathly ill, the Brownies and the ghost team up to try to rescue her, only to encounter a witch and her evil dragons and minions. Time is running out. They must rescue Mary from a fever-induced dream world before she is trapped there forever.
