Mathnet: "The Problem of the Missing Baseball, Part 5"
The Mathnetters head to the spot where the complaints from the previous episode ended. They come across a house that's similar to Mrs. MacGregor's house, except it has white shutters-Mrs. MacGregor's house has green shutters. Still, Kate investigates the house. As it turns out, its porch has a missing plank, just like Mrs. MacGregor's house, so it has to be the place.
Back at Mathnet HQ, the mathnetters examine a floor plan of Mrs. MacGregor's house, and determine that the ball would have landed in the fireplace. Howie is nervous that there might have been a fire in the fireplace. At the house, the owner hesitates when identifying himself, and claims that he doesn't know about the baseball. When he looks at a picture of the ball, he admits that he can't see it without his glasses. George hands him the glasses found at the site if Mrs. Macgregor's house and the owner identifies them as his, at which Kate and George realize that the man must be Clarence Sampson. Howie asks him if he had a fire in his fireplace and Clarence says it's a fake fireplace, at which Howie goes into the fireplace and recovers the ball, so now he can finally live a normal life!
Howie adds that the fake fireplace had "fake gold bricks," and Clarence says, "So that's where he hid them," making it obvious that he stole the house. It was the house that Clarence wanted, not the baseball. When Clarence stole the gold, he had an accomplice who had was living in the house before being arrested, and had made a fake fireplace out of the stolen gold bricks. At the end, Clarence is arrested, and Kate and George high-five each other.
