smoke,” Nancy said, standing up. She moved the beam
   of light back and forth across the ceiling. Finally, she
   found an area that seemed to be darker than the rest of
   the ceiling.
   She looked around for a stick or a branch. There was
   nothing but bones. She prodded at them until she
   found what she wanted. “How are you feeling?” she
   asked, rolling out a bone nearly seven feet long. “Can
   you give me a hand?”
   “I'm feeling okay,” George said. “You know me.
   Whatever it takes to get out of here.” Nancy thought of
   all of George's athletic achievements. She was sure her
   friend could handle this, too.
   Together, they held the long bone upright and
   poked at the ceiling where Nancy saw the darkened
   area. Showers of black powder fell on their faces.
   Nancy rubbed some of it off her cheek and smelled it.
   “Soot,” she said, with a grin. “Come on. There must be
   an opening up there somewhere.”
   Nancy and George hoisted the prehistoric bone,
   jamming it into the ceiling of the room. Clumps of dirt
   pummeled them from above, then splinters of wood.
   “I'll bet there's a trapdoor up there,” Nancy said
   when the bits of wood began falling. “The miners
   probably opened it as a vent when they built a fire.
   Keep pounding.”
   At last, the bone seemed to break through to
   another level. Dirt and roots rained down on them,
   then pine needles. “We're through,” George cried, as
   Nancy felt the bone move up with no resistance.
   “Okay, now what?” George said, as they looked at
   the hole seven and a half feet above the floor.
   “How about this?” Nancy asked. She tugged at an
   enormous skull lying against the wall. She and George
   were able to roll it across the floor to a spot beneath
   the vent in the ceiling. “We don't know who—or
   what—might be out there,” Nancy warned. “I'll go
   first. Wait until I signal.”
   Nancy climbed onto the skull and was able to get
   her head and shoulders through the opening in the
   ceiling. She hoisted herself up and out.
   “Okay, I'm clear,” she whispered through the vent
   back to George. “Wait while I check the front door.
   Maybe I can pick the lock.”
   “No way,” George said. “I'm out of here.” And she
   popped up through the trapdoor.
   They were on top of the small hill that the mine cut
   through. After scrambling down the hill, they followed
   the trail made by George's dragged body back to the
   fallen tree. They stayed hidden in the forest and didn't
   talk, in case their captors were still around. Finally,
   they reached the Private Property signs they had
   passed before. Then they crossed back into the federal
   land that surrounded the Mount Rushmore Memorial.
   After another half hour, they rejoined Bess and
   Kincaid, who were frantic. “What happened to you?”
   Bess asked.
   Nancy imagined how she must look—soot on her
   face, weeds and pine needles in her hair. “We'll talk on
   the way. We have to find a ranger—quick!”
   The four walked back down the nature path to the
   Mount Rushmore Visitor Center. On the way, Nancy
   and George related what had happened.
   When they reached the visitor center plaza, they saw
   a ranger standing on one of the terraces. “Good,”
   Kincaid said under her breath. “I've met her before
   with Clayton. Maybe we won't get into too much
   trouble sneaking around after hours.”
   She walked up to the ranger. “Hi,” she said with a
   winning smile. “I'm Kincaid Turner. I met you once
   with Clayton Simmons. His dad's a ranger here, too—
   Hillard Simmons.”
   The ranger frowned at them. “I know Clayton and
   his dad,” she said. “I don't know you. And I sure don't
   know what you're doing here after hours.” She spoke
   into her walkie-talkie and another ranger soon joined
   them.
   When the second ranger arrived, Kincaid introduced
   herself again. Then she introduced Nancy, Bess, and
   George. Before the two rangers could get another word
   out, Nancy and Kincaid began telling their story.
   They related their first experience here with the
   man on the trail. Then they told about the poachers at
   the Badlands and showed the rangers the photos.
   Nancy showed them the scrap of union card. Kincaid
   explained that they wanted to set up a sting to catch
   the possible poacher here. Then Nancy and George
   told what had just happened to them.
   The ranger called Clayton's dad. “He wants to speak
   to you,” she said to Kincaid.
   “Ranger Simmons, we really need your help,”
   Kincaid said. She listened for a minute, then said to
   Nancy, “He's completely up to speed. Clayton told him
   everything.” Then she spoke back into the phone.
   “We're sure we've found poachers' fossils,” she said,
   “and if someone doesn't get out there quick, they're
   going to lose the men and their hoard. We think one of
   them works here.”
   Ranger Simmons vouched for Kincaid and her
   friends to the other rangers and said he'd be right out
   with more men. Kincaid, Nancy, and George used a
   map to trace a rough path to the abandoned mine.
   “And you'll let us know what happens in your
   investigation?” Nancy asked as the rangers prepared to
   leave for the mine.
   “Yes, we will,” one of the rangers assured her. “Now,
   I suggest you leave here and get back home as quickly
   as possible. When that man finds you've escaped and
   can identify him, you could be in danger.” The girls
   hurried to their car.
   “George, how are you feeling?” Nancy asked. “Do
   you think you should get checked over?”
   “Nah, I'm fine,” George said. “I feel like Bess did
   when she nearly fell off the mountain. Just lead me to
   that shower and bed.”
   “One thing I don't understand,” Bess said. “How
   come those guys used a mine cave so close to the
   memorial?”
   “It's on private property,” Nancy said. “Maybe they
   own it. It's almost an hour's walk from the memorial
   and completely hidden and surrounded by trees and
   undergrowth. The opening is camouflaged in the side
   of a hill. If I hadn't followed the trail of dragged pine
   needles, I'd never have found it.”
   “So how did they get the bones in there?” George
   asked.
   “Because it's private property,” Nancy said, “we
   don't know what kind of roads might be back in there
   on the rest of the land.”
   “They had to have some way of getting the gold out
   at one time,” Bess said, nodding.
   “Matt's out of the hospital—we'll call him from the
   ranch,” Kincaid said. “It's after midnight. If I know
   Clayton's dad, he's probably called my folks and told
   them what's happened. They're goi 
					     					 			ng to worry until
   they see me home safe and sound.”
   Kincaid drove back to the ranch in record time.
   When they arrived, Melissa Turner ran out to meet
   them. “Hillard Simmons called us,” she said, running to
   the car. “George, how are you?”
   “I'm okay, Mrs. Turner,” George said, with a
   lopsided smile. “Really.”
   When they walked into the kitchen, Mr. Turner was
   seated at the table with Sheriff Switzer. The sheriff had
   his arm in a sling. “Matt, you didn't have to come out,”
   Kincaid said. “We were going to call you as soon as we
   got in.”
   T called Matt before we heard about your trouble,”
   Mr. Turner said. “We just had twelve more bison
   stolen!”
   15. All the Pieces Fit
   “No!” Kincaid said, tears welling in her eyes. “Twelve
   more?” She turned to the sheriff.
   “We just can't seem to get a handle on this thing,”
   the sheriff said, rubbing his shoulder. “There were
   tracks out there that made a pretty good match with
   the ones you lifted near Lulu's shelter,” he added. “But
   we can't match them up with anything around here or
   on file with the FBI. They don't match Badger Brady's.
   We know that.”
   “What about that gang from Canada you men-
   tioned?” Nancy asked.
   “That's not panning out,” Mr. Turner said. His
   elbows were on the table, and he held his head in his
   hands. “If we don't get this solved pretty soon, I don't
   know what I'm going to do. This last bunch included
   some of my best breeding stock.”
   “How about Ms. Francoeur?” Bess asked. “Did you
   ask her about the hubcap?”
   “Yes,” the sheriff replied. He told them what the
   Frenchwoman had said. It was the same story she had
   told Nancy and her friends at the tearoom, and they all
   agreed it was probably true.
   “Well, we have a new truck for you to check,” Nancy
   said. She could see in her mind the license plate of the
   truck in the Badlands.
   “Sit, everyone,” Mrs. Turner said, pouring coffee
   and tea. “I want to hear what happened to the girls
   tonight. Matt, I think you'll have a whole new case on
   your hands when you hear this.”
   When everyone was seated around the kitchen table,
   Nancy and her friends retold the entire story. Then
   Nancy showed Sheriff Switzer the photographs. “I
   recognize Jasper Stone all right,” he said. “We've had
   trouble with him before. I didn't know he was back in
   town. The other guy's a new one on me. But I'll check
   with the rangers at Rushmore and the Badlands
   tomorrow.”
   “I've got major work myself tomorrow,” Mr. Turner
   said, running his hand through his dark hair. “I've got
   to round up some more hands and pull the herd in
   even closer.”
   “You did that once, didn't you?” Nancy asked.
   “Yep,” Mr. Turner said, nodding. “But it wasn't close
   enough. It looks like I need to get them practically in
   the backyard to keep whoever it is from picking them
   off.”
   “Well, you girls have had another big day,” Mrs.
   Turner said. “Why don't we all go to bed. George, I
   really think you need some rest. Tomorrow we can all
   start fresh.”
   As they walked to the guest house, Nancy, Bess, and
   George were quiet. Nancy was frustrated. She felt as if
   she was working from both ends of a puzzle and
   couldn't get it to meet in the middle. That night, she
   had a hard time sleeping. She tossed and turned while
   her mind worked.
   Friday morning was sunny with a wide blue sky and
   tumbleweed clouds. Nancy, Bess, and George dressed
   quickly in jeans, shirts, and boots and hurried to the
   ranch house to meet Kincaid. Mrs. Turner offered the
   girls some breakfast, but Nancy shook her head. “I
   have an idea,” she said.
   “It must be a good one,” Bess said, “if you can brush
   off one of Mrs. Turner's doughnuts.”
   “Well, what is it?” George asked. “Spill it.”
   “What if the buffalo rustling isn't the point at all?”
   Nancy suggested.
   “What do you mean?” Kincaid said. “How could that
   be?”
   “What if it's just a ploy—a diversion?” Nancy said.
   “A diversion!” Kincaid repeated.
   “Something to keep all of you busy and distract you
   from what's really happening,” Nancy said. “And
   especially to keep you away from remote areas of the
   ranch.”
   “I don't get it,” Kincaid said.
   “When the buffalo are rustled, your father's
   response is to pull the herd in closer, right?” Nancy
   said.
   “Right,” Kincaid said.
   “Suppose something's going on at a remote area of
   your ranch,” Nancy suggested. “Something secret. And
   the best way to keep it secret is to keep all of you away
   from that area and so busy trying to solve one problem
   that you don't realize what's really going on.”
   Kincaid looked at Nancy and her eyes seemed to
   glow like spotlights. “A dig,” she whispered. “Oh,
   Nancy, that's it!”
   “A dig?” George said. “On the ranch?”
   “Of course,” Bess said, jumping up. “Think, Kincaid.
   Where are your secret spots? Are there any you haven't
   visited for a while?”
   “Sure,” Kincaid said. “Several.”
   Nancy grabbed a doughnut and headed for the door.
   “Come on, everybody. Let's go take a look.”
   At that moment the phone rang. It was Sheriff
   Switzer. Mrs. Turner switched the call to the speaker
   phone. “I talked to the rangers at Rushmore and the
   Badlands,” the sheriff said. “The second man in
   Nancy's photo was Ephraim Tell. He and Jasper Stone
   have a reputation with the FBI as criminal
   archaeological poachers. Stone owns the property that
   the abandoned mine is on.”
   “Have they arrested them?” Mrs. Turner asked.
   “The Mount Rushmore rangers found the mine and
   the fossils, but there was no sign of the two men. Since
   Nancy thought they might have been the ones who
   followed her and the others to Badger Brady's and
   locked them in the basement, I had them check out
   there, too. But they weren't there, either. Neither was
   the coyote, by the way.”
   Kincaid sighed, saying, “Where are they?”
   “We'll find them,” Sheriff Switzer said. “At least now
   we know who we're looking for. Oh, and Badger Brady
   has been arrested. He was picked up in Kansas.
   They're bringing him back tomorrow.”
   Nancy told the sheriff her theory about the men
   poaching on the Turners' land. “We know Jasper
   poached that jawbone from here years ago,” she added.
   “We're going to take a look around.”
   “You be careful,” the sheriff said. “Those guys might
   be dangerous. I'll be out with some men right away,”
					     					 			/>
   he concluded before hanging up.
   The girls raced to Kincaid's vehicle, as Mrs. Turner
   repeated the sheriff's warning.
   “There are two possible spots,” Kincaid said, as she
   took off across the pasture. “One of them is near where
   I found the jawbone. It's on the other side of the ranch.
   I haven't been there for a long time.”
   “Let's go there first,” Nancy said. “We know Jasper
   has been there before.”
   As they neared the area, Nancy noticed Kincaid's
   ringers. They were gripping the steering wheel so
   tightly, her knuckles were white. “Kincaid, what is it?”
   Nancy asked.
   “It's different,” Kincaid said. “There used to be
   some shrubs here. And what's that building?”
   Nancy and the others looked where Kincaid was
   pointing. There was a crudely built lean-to at the base
   of a hill. Kincaid parked the car, and they cautiously
   crept up to the shed. It was locked. Lying in the grass
   near the shed was a small pickax with the initials E.T.
   on it.
   “Ephraim Tell,” Bess said in a whisper.
   “Come on,” Kincaid said. Nancy and her friends
   followed Kincaid over the rise of a hill. “Whoa,”
   Kincaid said. The side of the hill was completely veiled
   in a tarpaulin anchored to the ground with dozens of
   stakes roped together. George and Kincaid pulled up
   the stakes. Nancy and Bess rolled back the tarp.
   There, embedded in the hill, was an enormous
   skeleton lying on its side. “It's a giant sea reptile!”
   Kincaid said. “I can't believe it. I've seen pictures of
   them, but never thought I'd ever be this close to one.
   They don't even have a name. It lived here when this
   spot was the bottom of a sea—over a hundred million
   years ago.”
   Bess put an arm around her friend's shoulder,
   saying, “Maybe they'll name it the Kincaidosaurus
   when you finish recovering it.”
   The sound of an approaching truck startled them.
   The girls ran back around the hill in time to see a black
   truck wheel around with a screech of its brakes and
   head away from the dig.
   “It's them—in the same truck we saw in the
   Badlands,” Nancy said, racing to Kincaid's vehicle.
   “They must have just seen our car. Come on, they're
   getting away.” Within minutes they were chasing the
   truck.
   For a mile or two, they sped over open pasture-land.
   “We need to trap them somehow,” Nancy said. “Chase
