Edgar and Alan Poe have returned home after their trips to Kansas and New Orleans. Though it is not quite a happy homecoming. Professor Perry has come back to Baltimore in order to take control over the twins. His plot even includes using a pendulum-like blade to kill one of the boys, so that he can communicate to the other side.
In the Great Beyond, the boys’ great-great-great-great granduncle, Edgar Alan Poe, has been watching over the boys. Though he was banished to the Animal Room, Poe is still trying to communicate with the boys to warn them.
What an ending to an amazing trilogy, with the puzzles and twists. This was read by Arte Johnson.
