The Mark of Athena (The Heroes of Olympus, Book Three) (37 page)

She might once have been a beautiful woman. Now black mandibles protruded from her mouth like tusks. Her other teeth had grown into thin white needles. Fine dark whiskers dotted her cheeks. Her eyes were large, lidless, and pure black, with two smaller eyes sticking out of her temples.

The creature made a violent

sound that might have been laughter.

“Now I will feast on you, my sweet,” Arachne said. “But do not fear. I will make a beautiful tapestry depicting your death.”

Leo wished he wasn’t so good.

Really, sometimes it was just embarrassing. If he hadn’t had such an eye for mechanical stuff, they might never have found the secret chute, gotten lost in the underground, and been attacked by metal dudes. But he just couldn’t help himself.

Part of it was Hazel’s fault. For a girl with super underground senses, she wasn’t much good in Rome. She kept leading them around and around the city, getting dizzy, and doubling back.

“Sorry,” she said. “It’s just…there’s so much underground here, so many layers, it’s overwhelming. Like standing in the middle of an orchestra and trying to concentrate on a single instrument. I’m going deaf.”

As a result, they got a tour of Rome. Frank seemed happy to plod along like a big sheepdog (hmm, Leo wondered if he could turn into one of those, or even better: a horse that Leo could ride). But Leo started to get impatient. His feet were sore, the day was sunny and hot, and the streets were choked with tourists.

The Forum was okay, but it was mostly ruins overgrown with bushes and trees. It took a lot of imagination to see it as the bustling center of Ancient Rome. Leo could only manage it because he’d seen New Rome in California.

They passed big churches, freestanding arches, clothing stores, and fast-food restaurants. One statue of some Ancient Roman dude seemed to be pointing to a nearby McDonald’s.

On the wider streets, the car traffic was absolutely nuts—man, Leo thought people in
Houston
drove crazy—but they spent most of their time weaving through small alleys, coming across fountains and little cafés where Leo was not allowed to rest.

“I never thought I’d get to see Rome,” Hazel said. “When I was alive, I mean the first time, Mussolini was in charge. We were at war.”

“Mussolini?” Leo frowned. “Wasn’t he like BFFs with Hitler?”

Hazel stared at him like he was an alien. “BFFs?”

“Never mind.”

“I’d love to see the Trevi Fountain,” she said.

“There’s a fountain on every block,” Leo grumbled.

“Or the Spanish Steps,” Hazel said.

“Why would you come to Italy to see Spanish steps?” Leo asked. “That’s like going to China for Mexican food, isn’t it?”

“You’re hopeless,” Hazel complained.

“So I’ve been told.”

She turned to Frank and grabbed his hand, as if Leo had ceased to exist. “Come on. I think we should go this way.”

Frank gave Leo a confused smile—like he couldn’t decide whether to gloat or to thank Leo for being a doofus—but he cheerfully let Hazel drag him along.

After walking forever, Hazel stopped in front of a church. At least, Leo assumed it was a church. The main section had a big domed roof. The entrance had a triangular roof, typical Roman columns, and an inscription across the top:
M. AGRIPPA
something or other.

“Latin for
Get a grip
?” Leo speculated.

“This is our best bet.” Hazel sounded more certain than she had all day. “There should be a secret passage somewhere inside.”

Tour groups milled around the steps. Guides held up colored placards with different numbers and lectured in dozens of languages like they were playing some kind of international bingo.

Leo listened to the Spanish tour guide for a few seconds, and then he reported to his friends, “This is the Pantheon. It was originally built by Marcus Agrippa as a temple to the gods. After it burned down, Emperor Hadrian rebuilt it, and it’s been standing for two thousand years. It’s one of the best-preserved Roman buildings in the world.”

Frank and Hazel stared at him.

“How did you know that?” Hazel asked.

“I’m naturally brilliant.”

“Centaur poop,” Frank said. “He eavesdropped on a tour group.”

Leo grinned. “Maybe. Come on. Let’s go find that secret passage. I hope this place has air conditioning.”

Of course, no AC.

On the bright side, there were no lines and no admission fee, so they just muscled their way past the tour groups and walked on in.

The interior was pretty impressive, considering it had been constructed two thousand years ago. The marble floor was patterned with squares and circles like a Roman tic-tac-toe game. The main space was one huge chamber with a circular rotunda, sort of like a capitol building back in the States. Lining the walls were different shrines and statues and tombs and stuff. But the real eye-catcher was the dome overhead. All the light in the building came from one circular opening right at the top. A beam of sunlight slanted into the rotunda and glowed on the floor, like Zeus was up there with a magnifying glass, trying to fry puny humans.

Leo was no architect like Annabeth, but he could appreciate the engineering. The Romans had made the dome out of big stone panels, but they’d hollowed out each panel in a square-within-square pattern. It looked cool. Leo figured it also made the dome lighter and easier to support.

He didn’t mention that to his friends. He doubted they would care, but if Annabeth were here, she would’ve spent the whole day talking about it. Thinking about that made Leo wonder how she was doing on her Mark of Athena expedition. Leo never thought he’d feel this way, but he was worried about that scary blond girl.

Hazel stopped in the middle of the room and turned in a circle. “This is amazing. In the old days, the children of Vulcan would come here in secret to consecrate demigod weapons. This is where Imperial gold was enchanted.”

Leo wondered how that worked. He imagined a bunch of demigods in dark robes trying to quietly roll a scorpion ballista through the front doors.

“But we’re not here because of that,” he guessed.

“No,” Hazel said. “There’s an entrance—a tunnel that will lead us toward Nico. I can sense it close by. I’m not sure where.”

Frank grunted. “If this building is two thousand years old, it makes sense there could be some kind of secret passage left over from the Roman days.”

That’s when Leo made his mistake of simply being too good.

He scanned the temple’s interior, thinking: If I were designing a secret passage, where would I put it?

He could sometimes figure out how a machine worked by putting his hand on it. He’d learned to fly a helicopter that way. He’d fixed Festus the dragon that way (before Festus crashed and burned). Once he’d even reprogrammed the electronic billboards in Times Square to read:
ALL DA LADIES LUV LEO
…accidentally, of course.

Now he tried to sense the workings of this ancient building. He turned toward a red marble altar-looking thing with a statue of the Virgin Mary on the top. “Over there,” he said.

He marched confidently to the shrine. It was shaped sort of like a fireplace, with an arched recess at the bottom. The mantel was inscribed with a name, like a tomb.

“The passage is around here,” he said. “This guy’s final resting place is in the way. Raphael somebody?”

“Famous painter, I think,” Hazel said.

Leo shrugged. He had a cousin named Raphael, and he didn’t think much of the name. He wondered if he could produce a stick of dynamite from his tool belt and do a little discreet demolition; but he figured the caretakers of this place probably wouldn’t approve.

“Hold on…” Leo looked around to make sure they weren’t being watched.

Most of the tour groups were gawking at the dome, but one trio made Leo uneasy. About fifty feet away, some overweight middle-aged dudes with American accents were conversing loudly, complaining to each other about the heat. They looked like manatees stuffed into beach clothes—sandals, walking shorts, touristy T-shirts and floppy hats. Their legs were big and pasty and covered with spider veins. The guys acted extremely bored, and Leo wondered why they were hanging around.

They weren’t watching him. Leo wasn’t sure why they made him nervous. Maybe he just didn’t like manatees.

Forget them, Leo told himself.

He slipped around the side of the tomb. He ran his hand down the back of a Roman column, all the way to the base. Right at the bottom, a series of lines had been etched into the marble—Roman numerals.

“Heh,” Leo said. “Not very elegant, but effective.”

“What is?” Frank asked.

“The combination for a lock.” He felt around the back of the column some more and discovered a square hole about the size of an electrical socket. “The lock face itself has been ripped out—probably vandalized sometime in the last few centuries. But I should be able to control the mechanism inside, if I can…”

Leo placed his hand on the marble floor. He could sense old bronze gears under the surface of the stone. Regular bronze would have corroded and become unusable long ago, but these were Celestial bronze—the handiwork of a demigod. With a little willpower, Leo urged them to move, using the Roman numerals to guide him. The cylinders turned—
click
, click, click.
Then
click, click.

On the floor next to the wall, one section of marble tile slid under another, revealing a dark square opening barely large enough to wiggle through.

“Romans must’ve been small.” Leo looked at Frank appraisingly. “You’ll need to change into something thinner to get through here.”

“That’s not nice!” Hazel chided.

“What? Just saying—”

“Don’t worry about it,” Frank mumbled. “We should go get the others before we explore. That’s what Piper said.”

“They’re halfway across the city,” Leo reminded him. “Besides, uh, I’m not sure I can close this hatch again. The gears are pretty old.”

“Great,” Frank said. “How do we know it’s safe down there?”

Hazel knelt. She put her hand over the opening as if checking the temperature. “There’s nothing alive…at least not for several hundred feet. The tunnel slants down, then levels out and goes south, more or less. I don’t sense any traps…”

“How can you tell all that?” Leo asked.

She shrugged. “Same way you can pick locks on marble columns, I guess. I’m glad you’re not into robbing banks.”

“Oh…bank vaults,” Leo said. “Never thought about that.”

“Forget I said anything.” Hazel sighed. “Look, it’s not three o’clock yet. We can at least do a little exploring, try to pinpoint Nico’s location before we contact the others. You two stay here until I call for you. I want to check things out, make sure the tunnel is structurally sound. I’ll be able to tell more once I’m underground.”

Frank scowled. “We can’t let you go by yourself. You could get hurt.”

“Frank, I can take care of myself,” she said. “Underground is my specialty. It’s safest for all of us if I go first.”

“Unless Frank wants to turn into a mole,” Leo suggested. “Or a prairie dog. Those things are awesome.”

“Shut up,” Frank mumbled.

“Or a badger.”

Frank jabbed a finger at Leo’s face. “Valdez, I swear—”

“Both of you, be quiet,” Hazel scolded. “I’ll be back soon. Give me ten minutes. If you don’t hear from me by then…Never mind. I’ll be fine. Just try not to kill each other while I’m down there.”

She dropped down the hole. Leo and Frank blocked her from view as best they could. They stood shoulder to shoulder, trying to look casual, like it was completely natural for two teenaged guys to hang around Raphael’s tomb.

Tour groups came and went. Most ignored Leo and Frank. A few people glanced at them apprehensively and kept walking. Maybe the tourists thought they would ask for tips. For some reason, Leo could unnerve people when he grinned.

The three American manatees were still hanging out in the middle of the room. One of them wore a T-shirt that said
ROMA
, as if he’d forget what city he was in if he didn’t wear it. Every once in a while, he would glance over at Leo and Frank like he found their presence distasteful.

Something about that dude bothered Leo. He wished Hazel would hurry up.

“She talked to me earlier,” Frank said abruptly. “Hazel told me you figured out about my lifeline.”

Leo stirred. He’d almost forgotten Frank was standing next to him.

“Your lifeline…oh, the burning stick. Right.” Leo resisted the urge to set his hand ablaze and yell:
Bwah ha ha!
The idea was sort of funny, but he wasn’t that cruel.

“Look, man,” he said. “It’s cool. I’d never do anything to put you in danger. We’re on the same team.”

Frank fiddled with his centurion badge. “I always knew fire could kill me, but since my grandmother’s mansion burned down in Vancouver…it seems a lot more
real
.”

Leo nodded. He felt sympathy for Frank, but the guy didn’t make it easy when he talked about his family mansion. Sort of like saying,
I crashed my Lamborghini
, and waiting for people to say,
Oh, you poor baby!

Of course Leo didn’t tell him that. “Your grandmother—did she die in that fire? You didn’t say.”

“I—I don’t know. She was sick, and pretty old. She said she would die in her own time, in her own way. But I think she made it out of the fire. I saw this bird flying up from the flames.”

Leo thought about that. “So your whole family has the shape-changing thing?”

“I guess,” Frank said. “My mom did. Grandmother thought that’s what got her killed in Afghanistan, in the war. Mom tried to help some of her buddies, and…I don’t know exactly what happened. There was a firebomb.”
