Context: The Bat has struck again, making off with a priceless necklace even after warning the police that he would rob the safe at precisely 1 a.m., after which he intends to go to country in order to give the police a rest. On his way through the village of Oakdale, the Bat notices someone robbing the Oakdale bank. Intrigued, the Bat follows the robber, who leads him to the old Fleming mansion.Inside the Fleming mansion, Cornelia van Gorder [Grayce Hamptom] and her ditzy maid Lizzie Allen [Maude Eburne] are discussing Cornelia's decision to rent the house for the summer. The big old house is a scary place, and Lizzie doesn't like the strange sounds, the strange caretaker [Spencer Charters], and the strange stories he tells about seeing ghosts in the house. Add to the fact that the Bat has taken to the country, and Lizzie is terrified of everything and anything. She's even gone so far as to set a bear trap outside her bedroom window, just in case the Bat decides to pay a vist. When Cornelia's niece Dale [Una Merkel], who works at the Oakdale Bank, returns home with her boyfriend Brook Bailey[William Bakewell] and tries to pass him off as a gardener, Cornelia is immediately suspicious (Cornelia: Any experience with alopecias? Brook: They dry up if you don't water them.), but Cornelia hires him anyway, at least until she can find out why Dale has brought him home.A rock suddenly comes crashing through the window. A note on it reads: Get out of the house now while there is still time. Immediately thereafter, Dr Venrees [Gustav von Seyffertitz] drops by to inform Cornelia that the Oakdale bank has been robbed of a half million dollars and that Fleming, Sr, the owner of the mansion, is returning from Europe so Cornelia will have to vacate the house. Then, a heavy painting moves, and a voice from behind warns them to get out of the house. Becoming concerned, Cornelia phones the police. When Detective Anderson [Chester Morris] shows up, Cornelia explains her suspicion that Fleming, Jr [Hugh Huntley] is trying to frighten her out of the house, possibly because he rented it to her while his father was out of the country. Nowthat his father is returning, she thinks he may be trying to frighten her into leaving.Soon everyone begins acting suspiciously. The doctor unlocks the broken window and "forgets" to relock it until Cornelia relocks it herself. Alone in the parlor for a few moments, Venrees unlocks the window again. Brook starts going around the house pounding on the walls. Dale phones Fleming Jr and asks him to come over. When he does, he brings a blueprint of the house so that they can locate a hidden room. Before they can find it, he is murdered, and Dale hides a piece torn from the blueprint under a tray. A storm is approaching, and the lightning knocks out the electricity. Someone phones from the garage, but when Det Anderson goes out to check, there is no one there. Detective Jones [Charles Dow Clark] arrives to help with the investigation. Dr Venrees finds the torn piece from the blueprint showing that the hidden room is behind a fireplace, but Det Anderson forces him to hand it over. When Anderson is poring over the blueprint, Venrees clobbers him with a heavy statue and locks his body in a closet. In the lightning flashes, the silhouette of the Bat can be seen peering into the window.It gets even more intriguing. Brook turns out to be a cashier from the bank and the primary suspect in the theft. Fleming Sr is seen walking on the roof when he's supposed to be out of the country. Dale finds the secret room behind a fireplace and gets locked in, along with the Bat, Mr Fleming Sr, and the money. The Bat shoots Fleming Sr. Dale escapes and leads Inspector Jones, Cornelia, and Dr Venrees to the secret room. Just as the fireplace swings open, Venrees blows out the candle, allowing whomever was in the room to escape. Finally, 
 Question: Where do Brook and Dale think the money from the robbery is hidden?
behind the fireplace

Context: Imagine a huge bar magnet passing through Earths axis, as illustrated in Figure 24.10. This is a good representation of Earth as a magnet. Like a bar magnet, Earth has north and south magnetic poles and a magnetic field. Although a compass always points north, it doesnt point to Earths geographic north pole, which is located at 90 north latitude (see Figure 24.11). Instead, it points to Earths magnetic north pole, which is located at about 80 north latitude. Earths magnetic south pole is also located several degrees of latitude away from the geographic south pole. A compass pointer has north and south poles, and its north pole points to Earths magnetic north pole. Why does this happen if opposite poles attract? Why doesnt the compass needle point south instead? The answer may surprise you. Earths magnetic north pole is actually the south pole of magnet Earth! Its called the magnetic north pole to avoid confusion. Because its close to the geographic north pole, it would be confusing to call it the magnetic south pole. Like all magnets, Earth has a magnetic field. Earths magnetic field is called the magnetosphere. It is a huge region that extends outward from Earth for several thousand kilometers but is strongest at the poles. You can see the extent of the magnetosphere in Figure 24.12. For an animated version of the magnetosphere, watch the video at this URL: MEDIA Click image to the left or use the URL below. URL: Do you like to read science fiction? Science fiction writers are really creative. For example, an author might write about a time in the distant past when compasses pointed south instead of north. Actually, this idea isnt fictionits a fact! Earths magnetic poles have switched places repeatedly over the past hundreds of millions of years, each time reversing Earths magnetic field. This is illustrated in Figure 24.13. Scientists dont know for certain why magnetic reversals occur, but there is hard evidence showing that they have occurred. The evidence comes from rocks on the ocean floor. Look at Figure 24.14, which shows a ridge on the ocean floor. At the center of the ridge, hot magma pushes up through the crust and hardens into rock. Once the magma hardens, the alignment of magnetic domains in the rock is frozen in place forever. The newly hardened rock is then gradually pushed away from the ridge in both directions as more magma erupts and newer rock forms. Rock samples from many places on the ocean floor reveal that magnetic domains of rocks from different time periods are aligned in opposite directions. The evidence shows that Earths magnetic field reversed hundreds of times over the last 330 million years. The last reversal was less than a million years ago. What might happen if a magnetic reversal occurred in your lifetime? How might it affect you? You can learn more about Earths magnetic reversals at this URL: . The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. However, explaining why Earth acts like a magnet is a relatively recent discovery. It had to wait until the development of technologies such as seismographs, which detect and measure earthquake waves. Then scientists could learn about Earths inner structure (see Figure 24.15). They discovered that Earth has an inner and outer core and that the outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated by the movement of charged particles through the molten metals in the outer core. The particles move as Earth spins on its axis. The video at the URL below takes a closer look at how this occurs. MEDIA Click image to the left or use the URL below. URL: Earths magnetic field helps protect Earth and its organisms from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles, where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole and tell direction. Many animals have natural "compasses" that work
