The Wright 3

Supersleuths Petra and Calder, along with Calder's old friend, Tommy, have been cryptically drawn into another mystery— this time involving a Frank Lloyd Wright architectural masterpiece, the Robie House.

When the kids' sixth-grade class attempts to save the house from demolition, eerie events are reported: Voices float out from within, shadows shift behind the art-glass windows, even the roof moves. Soon Petra, Calder, and Tommy are involved in a frightening search for ghosts, hidden treasure, and a coded message left behind by Wright. Can they pursue justice and escape with their lives?
