The Phantom of Sneer Mansion! was episode 46.
Strange things happen down at the old theater, when Cyril tries to put on Cedric's play, "The Mystery of the Haunted Treasure". It is up to Bert Raccoon: Ace Reporter (and the others) to find the culprit! All the while, Cyril tries to get Lady Baden-Baden a larger roll in Cedric's play so he can get in on Mr. Knox's "big deal".
Cyril re-opens the theater in Sneer Mansion with a play he has written in order to ascertain he gets a big deal from Knox. Of course, the phantom which haunts the theater is not pleased with the decisions Cyril has made and he proceeds to turn his haunting toward the adversarial aardvark.
With Bert Raccoon: Ace Reporter and Super Sleuth on the case, he gets a valuable tip from Melissa who rightfully confirms that the phantom only intervenes when Cyril interferes with Cedric's play. Of course, since Cyril is into meddling, the phantom recurs numerous times.
Finally, the phantom's true identity is revealed to be an old friend of Lady Baden-Baden's, Edward Miller. And finally, Cyril relinquishes his commandeering ways and allows Cedric's play to go on as it should.
