Lea shuddered. “Please don’t mention that name.”
“I’m sorry,” he said, looking around the cave.
“Amazing to think this place was used by the gods though,” Camacho said. “I still can’t get my head around that.”
“Me neither.” Kamala stared up at the moonlight struggling to reach this deep into the cave. “But it sure is beautiful here.”
Ryan stood beside her and looked up at the pale light. “It also has a special meaning as a pilgrimage site. Pythagoras was initiated into one of the ancient mystery cults right here in this very place. It’s massively significant, maybe because they knew what we just found out a few hours ago.”
“That it’s the burial place of Orpheus?” Zeke asked.
Camacho said, “Give that man a cigar.”
“Hold the cigar,” Ryan said. “We’ve reached the sanctuary.”
Inside, there was so little light they reached for the flashlights. Sweeping the beams over the unhewn marble, Hawke let out a long whistle. “I bet this place is keeping a few secrets.”
“The main one being the Tomb of Orpheus,” Lea said.
Reaper kicked a rock into the pool. “But where do we start? I cannot see any obvious place where a tomb might be accessed.”
Scarlet angled her flashlight beam up onto the cave roof. “Are you sure this is the right place, boy?”
“It’s the right place, Cairo. The poem clearly stated Orpheus’s desire to be buried in the sanctuary.”
“Which means only one thing.” Lea raised her chin and looked up into Hawke’s eyes.
He frowned. “Don’t say it.”
“Someone’s going for a swim.”
“I said don’t say it.”
She shrugged. “It’s why I love you, you big macho hunk.”
“All right, all right,” he said. “Stop buttering me up. I know what I have to do. Ryan, dive in that rockpool and see if you can find an entrance to the tomb.”
Ryan looked shocked. “Eh?”
Lea rolled her eyes and slapped Hawke’s shoulder. “Get your clothes off, Josiah.”
“Wouldn’t you rather wait until we were back at the hotel?”
A devilish smirk crossed her lean, tanned face. “Now!”
When Hawke resurfaced for the third time, he gave a thumbs up and they all saw the big smile on his face. Pulling himself from the cold water, he grabbed his shirt and dried his face with it, eliciting an eye-roll of despair from Lea. “Looks like we’re in business.”
“What did you find?” she asked.
“At the far end of the pool, just under that rocky ridge over there that almost reaches the surface. There’s a loose rock with an opening to one side. It’s all underwater and the rock wouldn’t budge when I tried to move it.”
“What can we do?” Zeke asked.
Ryan scratched his chin. “If we had a winch on the SUV we could drive it up here and pull it out.”
Lexi put her hands on her hips and let out a long sigh. “Yeah, and if Iron Man was on our team he could fly down there and blast it out with his repulsors.”
“What’s your point?” Ryan asked.
“My point, Peabody, is that we don’t have a goddam winch on the SUV, so why bring it up?”
“Just thinking out loud.”
“I wondered what that smell was,” Lexi said. “I thought it might be some kind of cave mould.”
Ryan grinned. “Seriously though, you watch The Avengers?”
“Maybe.”
“I never had you down as a superhero sort of gal.”
Lexi raised her hand and wiggled the steel prosthetic fingernails. “Really?”
He dipped his head. “Come to think of it…”
Kamala gave them both a long, withering glance as she walked over to Hawke and came up with her own suggestion. “What about dynamite?”
Hawke shrugged. “Submarine blasting is a dangerous business.” He ran a hand through his hair and swept as much water out of it as he could. Flicking the water from his hand onto the cave floor, he said, “But at least the water’s not moving because that makes it much harder.”
“Like a river?”
“Precisely.”
“So what the hell are we going to?” Zeke asked.
“I’ll drive back to Heraklion and pick something up.”
Lexi crossed her arms and slumped against a boulder. “I don’t think the local supermarket stocks dynamite, Zeke. Plus, the shops are probably shut.”
“Opening hours really don’t apply to us,” Scarlet said.
“And dynamite is rarely used these days anyway,” Hawke said. “Water-gel explosives are the go-to blasting agent now. Tri-nitro-toluene. Much safer to handle than stuff like nitro-glycerine and perfect for underwater demolition. Problem is, they’re unlikely to stock that at the local supermarket either, or the primer and detonating cord we need to make it go pop — whatever the opening hours.”
Kamala raised an eyebrow. “Make it go pop?”
“Yeah, you know,” he said with a smile. “Detonate it.”
“I know what you meant,” she said. “I just thought your choice of words was a little misleading.”
“Hawke is a master of understatement,” Camacho said with a laugh.
“So can we make this stuff ourselves?” Ryan said.
Hawke shrugged. “If we had the right ingredients, maybe. We’d need some sodium nitrate, ammonium nitrate and methylammonium nitrate… fuel oil, silica…”
Lea sighed. “In other words, no.”
“So we’re as fucked as the ship’s…”
“Thank you, Ryan,” Scarlet said, “but please leave the crude gags to me. I pull them off with so much more panache.”
“Yes,” Ryan said without hesitation. “Word on the grapevine is that you certainly are able to pull things off with panache.”
She cocked an eyebrow. “In your wildest dreams, Sputnik.”
“Can we get back to business now?” Lea said. “Because right now it looks like we’re pretty much screwed.”
“Nil desperandum, plebs,” Ryan said. “If we can get some solid CO2…”
Kamala frowned. “Huh?”
“Dry ice.”
“Ah.”
“Wait a minute,” Reaper said. “Did you just call me a pleb?”
“As I was saying.” Ryan took a big step away from the Frenchman. “If we can get some dry ice, a few sealable containers and a watertight bag, then all we have to do is fill the containers with it, stuff them into the rock fissures and then we get our pop.”
“A dry ice bomb?” Nikolai looked sceptical. “And this will work?”
He nodded. “You fill a sealable bottle with some water, then add the dry ice chunks. As the dry ice warms up it turns to gas and that gas expands causing an explosion. As the explosion hits the surrounding water it oscillates. This is because the water pressure is going to be greater than the power of the CO2 gas as it expands, meaning it forces the explosion inwards again until the power of the explosion becomes greater than the water pressure once again, and then you get another expansion.”
Zeke took a step back. “What the hell?”
“He means you’ll get more than one explosion,” Lexi said, looking at Ryan. “Right?”
“Absolutely right, and I only wish I had a treat to throw you.”
Lexi raised her middle finger. “Try it.”
“Thanks for your input, Lex.” Hawke stepped up. “Ryan, would this produce enough force for what we want?”
“How much does the rock weigh?”
Hawke took a second out to estimate what he had seen underwater. “It’s not massive, but I’d say at least a hundred kilos.”
“But you said there was already a fissure?”
