The Secret of the Cunning Mermaid

Who sneaked into the library of the village of Krasnye Gory in the middle of the night? Why did an unknown person need an old, unsigned painting that had been in plain sight for fifty years? Why was a man almost drowned at the Bor Pond on the night of the robbery? And how did the fragments of the frame, which bordered the stolen painting, end up on the shore?

Only by answering these and many other questions will the members of the Secret Brotherhood of the Maple Leaf be able to complete their new investigation.
