Description 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?.
