And then my aunt told me about the clue and the treasure, and I thought I could get that for myself. Beckworth boasts that he's hidden his "great treasure" where no one can find it, and then he offers this clue-"if fortune is what you seek sincere, the only place to look is here." Beckworth was a bootlegger during prohibition, which meant he had to smuggle liquor into the house and hide it someplace the authorities couldn't find it. Come out. Found it! Have Rigsby and Van Pelt set up on the mansion tonight. He was the original owner of this house-built it. I don't believe that's a mistake. It's an old conjurer's trick- a simple optical illusion. Jane: And be sure to ask about the ghost, too. Jane: So he could amaze and terrify his guests with his mastery of the occult, and it's been used recently. Jane: Walter Beckworth's treasure he hid in the mansion. Lisbon: Somehow the killer got into the house without tripping the alarm or turning it off. Lisbon: What the hell is the matter with you?! No ghosts. People say he haunts the place. Pepper's ghost. Screw the CBI. That son of a bitch. The Beckworth mansion
Rigsby: Nothing on the exterior of the house. The word "here" is misspelled in the riddle. There's a system of pipes that carry sound throughout the house. This house is riddled with secret passages. Van Pelt: So the killer didn't come through the front door. Victoria: My nephew is a lawyer. Whoever killed Foster was simply trying to scare him from the mansion. You fix it then.

Summary: The CBI team is called to investigate the death of the wealthy new owner of the old Beckworth Mansion, which is the site where his murdered body was found. The victim and his wife bought the Mansion with the hope of fixing it up, and the sentimental former owner developed a grudge. The local deputy sheriff, and other witnesses, believe that Walter Beckworth's ghost haunts the mansion and killed the new owner, so the investigation is accompanied by a discussion about the existence of ghosts. Jane discovers that the ghost was actually an illusion created by a system Beckworth built into the house to entertain his guests and also points out that the house is full of secret passages that the killer could have used. The CBI team and others, headed by Jane, then try to find a treasure supposedly hidden in the house, and come upon a riddle instead. The killer (the former owner's jealous nephew) is tricked into sneaking undetected into the mansion again in an attempt to locate the treasure, whereupon he is apprehended by the CBI upon arrival. Jane then reveals that he wrote the riddle himself. Van Pelt and Rigsby become closer during this episode, and finally express their feelings for one another.
