Choosing the least steep streets, they gradually worked their way up into the foothills of Old Mother Mountain. At least that's what most of the townspeople called it. To Jesse and Daisy it was now the Hobhorn, in honor of their friend, Her Royal Lowness Queen Hap, ruler of the hobgoblins of the Hobhorn, whose kingdom lay inside the mountain.

Old Mine Lane dead-ended a quarter of a mile from what had once been the entrance to the gold mine. They knew that the old castle sat smack at the end, not that either of them had ever seen it. It had been blocked off from outsiders by a high wall overgrown with bushes and vines since before they were born. The number of houses along the road 51.began to dwindle until there were just weed-choked vacant lots. The cousins finally arrived at the end of the road, where a brand-new plywood wall loomed at least fifteen feet high. It was the kind of wall you'd see at a city construction site, except this one didn't seem to have any peepholes for curious pedestrians to look through.

The cousins parked their bikes and waded through the weeds over to the wall. A big new sign warned, NO TRESPa.s.sING. GUARD DOGS ON PATROL.

"Guarding the poor professor would be my bet," Daisy said.

Emmy growled, baring her teeth, the fur along her spine standing up.

"I know just how you feel, Em," said Jesse. "Let's check it out."

They walked along the wall, Emmy leading the way with her snout, nosing around for an entrance or a gate or a driveway. But they just kept following the plywood around until about fifteen minutes later, when they found themselves right back where they had started.

"Weird," the cousins said together, exchanging looks of deep perplexity. How did anyone get in or out? On the other side of the wall, they heard a loud, persistent buzzing sound.

Jesse looked around. There wasn't even a tree 52.nearby to climb to get a look over the wall.

"We need a ladder," said Daisy.

"Or a good leg up," Jesse said.

"Will I do?" Emmy asked, startling them both by suddenly unmasking into a dragon.

"Emmy!" Jesse and Daisy cried out together and looked around, afraid she would be seen.

"Don't worry. No one will see," Emmy said. "Come. Climb up onto my shoulders and spy."

Jesse hesitated. "It won't hurt you?" he asked.

"Do I look like a delicate dragon to you? Don't be a dork," Emmy said. "Climb." She turned around.

Jesse climbed up the ramp of her tail, his sneakers getting surprisingly good traction, and made it up as far as the back of her neck. But even if he were to stand on top of Emmy's head (which did not not seem like a good idea), his own head would still be a good three feet from the top of the wall. He signaled to Daisy, who nodded and quickly scrambled up after him. seem like a good idea), his own head would still be a good three feet from the top of the wall. He signaled to Daisy, who nodded and quickly scrambled up after him.

Jesse said to her, "I'll give you a boost up and you spy."

Jesse bent down and offered Daisy a stirrup made from his linked hands. Daisy placed her hands on his shoulders and her foot in his hands. Jesse grunted as he lifted Daisy up. She wasn't very 53.heavy, but Jesse felt himself wobbling beneath her weight.

"I have you, Jesse," said Emmy. He felt her talons enclosing his calves, steadying him.

"I'm up!" Daisy whispered, holding on to the top of the wall and peering over. She was amazed at how new the castle looked, as if the last stone had been set into place only that morning. "Wow!"

"Ask her what she sees," Emmy whispered up to Jesse.

Jesse whispered up to Daisy, "What do you see?"

Daisy whispered back, "It looks exactly exactly like the castle we saw online, Jess. It's got three stone towers, two small and one big. And the ramparts are made of wood." like the castle we saw online, Jess. It's got three stone towers, two small and one big. And the ramparts are made of wood."

"Are they riveted with sa.r.s.en stones?" Jesse asked.

"What's a sa.r.s.en stone?" Emmy whispered.

Daisy ignored them both. "I see squint holes," she said, "and killer holes, too."

"Murder holes," Jesse corrected. holes," Jesse corrected.

"Whatever . And it's double-walled." . And it's double-walled."

"Ask her what the buzzing noise is," Emmy told Jesse.

Daisy heard Emmy's question. "Lots of things. Lawn mowers. Trimmers. Other landscaping tools,"

54.Daisy said. "There's a whole crew of workmen cutting gra.s.s and whacking weeds on the grounds outside the wall. Jesse, it really is a life-size replica of Uffington Castle. And to think it's just been sitting here..."

Jesse said, "St. George built it when he was head of the mining company a hundred years ago."

"And Sadie Huffington used magic to fix it up," Daisy said. Either that, or the army of sweating, shirtless workmen who were now toiling away on the lawn had worked very hard and very fast to whip the castle back into shape. Now they were digging holes for saplings, setting the root-b.a.l.l.s into the holes, filling in the holes, and making neat circles of stone around the newly planted trees. A harnessed team of dogs dragged a sled loaded down with piles of cut stone.

Emmy whispered up to Daisy, "Tell us more."

Just then, Sadie Huffington strode through an arch in an outer wall. Even in the heat, she wore a long black coat that reached her ankles.

"I'm looking at the Top Dog herself," Daisy said.

"Yikes," Jesse said. Daisy felt Jesse's arms begin to tremble beneath her feet.

"She's wearing a black coat that looks exactly like St. George's," Daisy reported.

55."Boy! She must be boiling," said Jesse.

"I don't know...she looks like a pretty cool customer to me," Daisy said as she watched Sadie Huffington stop before the dog team and reach into a cloth sack slung across her shoulders. "Ugh," she said.

"What's going on?" Jesse whispered, giving Daisy's legs an impatient squeeze.

"She's got a bunch of dogs pulling a sled," said Daisy. "And she's got this b.l.o.o.d.y sack full of raw meat...and she's feeding the meat to the dogs."

"Hey, do you think those are the dogs that are missing from the pound?" Jesse said.

"That's exactly what they are," Daisy said. Sadie Huffington was walking among the men now. "Oh, wow! She's feeding the men men raw meat, too!" she whispered. raw meat, too!" she whispered. "Ick "Ick ." As each workman got his bit of b.l.o.o.d.y raw meat, he chewed it up, not neatly like a man, but sloppily and greedily like a dog. Sadie scratched one of the men behind the ear. Another man scratched his armpit, then shook himself from head to foot. ." As each workman got his bit of b.l.o.o.d.y raw meat, he chewed it up, not neatly like a man, but sloppily and greedily like a dog. Sadie scratched one of the men behind the ear. Another man scratched his armpit, then shook himself from head to foot.

"Holy moly," said Daisy. "I think she's done worse than just stolen them from the pound."

"What?" Jesse and Emmy both whispered fiercely. Jesse and Emmy both whispered fiercely.

"The men," said Daisy. "I think Sadie might 56.have turned some of the dogs dogs ...into ...into men." men."

"Whoa!" Jesse said. "Really?"

"Well, they're eating raw meat without using their hands or getting grossed out," said Daisy. "And they're panting. If they had tails, I bet they'd be wagging them."

Jesse's arms started to shake again. "Whoa again," he whispered.

"She's nothing but a witch," Emmy said. "A wicked, wicked wicked witch." witch."

Daisy watched as Sadie Huffington bent to examine one of the rock circles. She rose up and, raising her switch, thrashed the nearest worker. No red meat for him! "She just whacked one of the men with that whip of hers," she reported grimly.

"Witches make very bad Keepers," said Emmy in a loud whisper.

It saddened Daisy to see any living creature, man or dog, being treated this badly. She looked away and scanned the ramparts, nearly crying out when her gaze fell upon two of the biggest dogs she had ever seen. They were pacing the battlements just outside the large tower.

"What's the big tower called, Jess?" Daisy whispered.

"The donjon," Jesse told her.

"Right, and you said it's where they kept 57.prisoners in olden times?" Daisy asked.

"Yep," Jesse said. "My arms are getting tired. Are you almost done spying, Daze?"

"Just a sec," Daisy told him. She couldn't take her eyes off the dogs. Everything about them was huge: their heads, their paws, their blue-black tongues, their eyes. The one nearest Daisy stopped and turned its enormous s.h.a.ggy head in her direction. Then it opened its jaws and let loose a howl that vibrated the wood beneath her fingers. Daisy reared back and lost her grip on the wall. She teetered so wildly that Jesse lost hold of her, then Emmy let go of Jesse, and all three of them went toppling toward the earth.

CHAPTER FOUR

HIGGLETY PIGGLETY POP!

"What's the big idea!" Daisy whispered furiously. She dabbed her tongue on the bottom of her shirt and showed them the dot of blood. "Look! You guys made me bite my tongue!"

59.Emmy, masked again into dog form, whined apologetically.

Jesse c.o.c.ked a thumb toward the road. "We've got company."

The dogcatcher's truck made a slow turn in the cul-de-sac. Ms. Mindy leaned out the window and called to them, "What are you kids doing so far away from home?" She looked a lot less cheerful and considerably more frazzled than she had the morning before at the library.

"Checking out the blackberry bushes!" Daisy called back to her. "My pop knows we're here."

Ms. Mindy nodded. "Well, news flash. I've had ten reports of runaway dogs since my shift started this morning. First the break-in and now this. If I were you, I'd take my doggie on home and sit tight till we figure out what's going on."

"Sure thing!" Daisy told her.

Jesse and Daisy and Emmy watched as the truck turned around and went slowly back up the road.

When the dogcatcher was out of sight, Jesse lay back in the weeds and felt the sweat pouring off him. All around, the weeds buzzed with the sound of cicadas. It was a hot sound, like live electricity. He knew they needed to pick themselves up and 60.figure out how to find the professor, but it was too hot to move and almost too hot to think. "I wonder if Ms. Mindy has any idea those dogs she's looking for are all on the other side of that plywood wall."

"There's no way she could know," Daisy said. "And we can't tell her, either. For all we we know, Sadie Huffington can turn people into dogs just like she turns dogs into people." know, Sadie Huffington can turn people into dogs just like she turns dogs into people."

"I wonder what kind of dog I'd be," Jesse mused.

"A mutt, probably," Daisy said.

"Good," Jesse said. "Give me a mutt any day over one of those nervous Nelly breeds."

"How can you say that?" Daisy said. "Emmy's a breed, and she's no Nelly."

Emmy woofed.

"Emmy's a dragon dragon , you dork," Jesse said. , you dork," Jesse said.

"Oh, right," Daisy said, laughing.

Jesse said, "Do you think one of those dogs could be the professor? What kind of dog would she turn him into, I wonder. She called him a hound dog, but I'm thinking he'd be one of those nifty little terriers, you know, like in Higglety Pigglety Pop!" Higglety Pigglety Pop!"

"I think he's a prisoner in the donjon," she said.

Jesse sat up quickly and looked at Daisy. Her face was bright pink from the heat and she was 61.chewing on a long blade of gra.s.s. "What makes you so sure?" he asked.

"Just before you guys let go of me? I saw these two giant black dogs patrolling the ramparts just outside the big tower. I swear, they were the biggest, scariest dogs I've ever seen. Their tongues were dark blue and their teeth were...I don't even like to think of those teeth. Those vicious dogs have a job to do--and that's guarding the very important prisoner in the tower. I'm sure of it."

Jesse nodded. "They sounded sounded big, like maybe Tibetan mastiffs. I wouldn't want to tangle with big, like maybe Tibetan mastiffs. I wouldn't want to tangle with one one of those, let alone two. Well, if they're guarding the professor, then we need to find a way around them." of those, let alone two. Well, if they're guarding the professor, then we need to find a way around them."

"But how?" Daisy said. "We can't leave him there much longer! Who knows what she has planned for him."

Jesse sat there in the buzzing weeds and thought hard. "I've got it!" he said after a moment. "We go to the library and look for a book about the historic homes of Goldmine City. The castle is bound to be in it. Maybe it'll have floor plans and we can find a way to get into the tower without pa.s.sing the mastiffs."

"Brilliant!" said Daisy, scrambling to her feet. "Let's go."

62.Emmy leaped up, too, and yipped with enthusiasm.

They retrieved their bikes and took off, the cool breeze drying their sweaty backs as they coasted downhill into town. Parking in the rack in front of the library, they climbed up the wide stone steps. Daisy knelt to fasten Emmy's leash to the Chicken Box while Jesse grabbed ahold of one of the big bra.s.s door handles and pulled. The door didn't budge. It was locked. He tried the other door. That one was locked, too. He cupped his hands to the gla.s.s and peered into the library. The lights were off. "It's closed!" he said with a groan. "In the middle of a weekday! How could they do this to us? Why?"

Daisy pointed to the handwritten note taped to the door.

Temporarily closed. Preparing for the Pets Allowed Party. See you at six!

"Right. Forgot all about that," said Jesse.

Daisy vibrated with impatience. "Where are you, Mr. Stenson?" She turned to Jesse. "Do you think he's in the back room? I bet if we knock real hard, he'll come. I'm sure he'll let us in to get a book. He's got to. I mean, we have special privileges.

63.This is an emergency. How could he say no?"

With Jesse and Daisy pounding on the door and Emmy throwing herself against it, they managed to kick up quite a ruckus. But no one came. Finally, they quit banging and leaned their hot foreheads against the cool gla.s.s. Suddenly, Daisy straightened and cried out, "Jess, look! Somebody's in there. See? Over there, by the d.i.n.ky water fountain?"

Next to the low water fountain, the one for the littlest kids, Jesse saw someone a good deal smaller and odder-looking than a little kid. It looked like a he, with a flimsy little torso and long, gangling arms and legs and a great big noggin--sort of like one of the house-elves in the Harry Potter books, only dustier-looking and with sharper features. Everything about his head was sharp: the bones of his skull, the big nose that hooked down and the big chin that hooked up, the jutting cheekbones, the pointy ears, and the piercing eyes that turned up at the corners--all topped off with a tuft of hair the color of dust bunnies. And this very peculiar-looking creature was, at that very moment, staring directly at them...and beckoning!

Emmy let out a shrill bark and the creature jumped into the air, darted across the library, and disappeared into the adult stacks.
