Finally, they were at the base of the rotunda, staring up at the columns.
âJust like Beaconsfield,' Gerald said. âIt's in ruins, sure, but it's exactly the same.'
âCan't you just see the Major and Mr Chesterfield walking up there,' Ruby said, her voice a library hush. âJust before theyâ¦' She didn't finish the sentence. The vision of the two men being cut down in a volley of arrows was still fresh in her mind.
âHow can there be one of these buried under Beaconsfield and another one perched on a Greek mountainside?' Sam said. âI mean, it's not like they come flat-packed with an allen key. What's the connection?'
Gerald sat on a broken plinth and gazed up at the ruins. âI think when we can answer that, we can answer everything.'
A dragonfly droned past Gerald's ear and he took a distracted swipe at it. Ruby settled onto a boulder next to him. âSo let's go over what we know,' she said. âYour great aunt left you a bunch of letters.'
âWhich the thin man stole from my bedroom in London and gave to Mason Green before I could read them,' Gerald said.
âRight. Now we know that one of the envelopes had the word Delphi written on the front.'
âYep.'
âWhat was on the other ones?'
âUm,
Family Treeâ¦
'
âWhich Mason Green used to connect you with Quintus and his sons,' Sam said.
ââ¦and
Fraternity
.'
âWhich was the brotherhood in India that swore to protect the emerald casket,' Ruby said. âBoth your family tree and the Fraternity are central to this mystery. So Delphi must be really important as well. Otherwise, why would Geraldine single it out? And why would Lucius carve it in stone as his dying act? This must be the place. Gerald, give me your backpack.'
Ruby fished out the guidebook and flipped to a dog-eared page.
âLook, here's a map of Delphi,' she said, holding the book up for Gerald. âThis must be the road we followed out of town. We came around this bend, so down here must beâ'
âThe Sanctuary of Athena,' Sam said.
Ruby and Gerald both looked up at him.
âHow did you know that?' Ruby asked.
Sam pointed to a block of stone by their feet. âIt's carved into the side of that thing,' he said.
Ruby exhaled and turned back to the guidebook. âThank you, geography boy. Invaluable, as ever. Now, it says that this building was called the Tholos. It dates back to the fourth century BC.'
âWow,' Gerald said. âOld.'
âNo one knows exactly what it was used for but it could have been a meeting place, or a burial chamber,' Ruby said.
âThat makes sense,' Gerald said. âGaius was buried under the one at Beaconsfield. That's where the professor found this ring.' He held out his right hand and studied the gold band. Then he held out his other hand. âAnd this one was with Lucius in France.'
Sam picked up a handful of pebbles and started tossing them into the undergrowth. âSo the ring that Charlotte has round her neck must be from Marcus,' he said. âFrom India.'
âOf course,' Gerald said. âIt was Viridian, Mason Green's ancestor, who killed Marcus, trying to find the emerald casket. He must have stolen it, and it's been passed down through the family.' Gerald closed his eyes and thought hard. âThree brothers. Three rings. Three caskets.'
âAnd three golden rods,' Sam said. âDo the rods somehow unlock the treasure of Delphi?'
Gerald tilted his head back and took in the view. It was so tranquil. From nearby came the sound of water tumbling over rocksâa spring or underground stream perhaps? Stray cats warmed themselves on sun-baked stones. Wildflowers added sprays of purple and red to the marble white and blue sky. Gerald could see how Delphi had been the ancient world's spiritual capital. It was a place ripe for contemplation.
âOkay, how's this for a theory,' Gerald said. Sam and Ruby turned to him. âMy ancestors were sent here on a secret mission by the emperor of Rome. That mission was to steal the greatest fortune ever amassed in the ancient world: the treasures of Delphi. But when Quintus and his sons get here they see just how vast the treasure is.'
âWhat? And they decided to take it for themselves?' Ruby said.
âDo you remember what Green said to us outside the Rattigan Club? Greed can make people do strange things. And what did you say before, Ruby? The main street of Delphi was lined with banks brimming with gold and diamonds? That would tempt the strongest man. I think Sam's right. Somehow, the three golden rods unlock the vault where the treasure is hidden.'
âSo if they had the golden rods, why didn't they steal the loot and take off?' Sam said.
âMaybe it was just too much to haul away,' Gerald said. âAnd maybe they didn't trust each other.'
âI bet that's it,' Ruby said. âThey put the rods into three different caskets, and then gave each other a different key: a diamond, a ruby and an emerald. That way no one of them could open the vault, or whatever it is, without the other two being there. Then they split up.'
âBut why split up?' Sam said. âThat's what I don't understand.'
âMaybe they'd agreed to meet back here at a set date and bring horse carts or whatever to haul the money away,' Gerald said.
âBut wouldn't they already have carts with them if they were going to steal it all for the emperor anyway?' Sam said.
Gerald rubbed his chin. âThat's a good point,' he said. âI can't answer that. But that's the best theory I can come up with. And when the emperor learned that his loyal servants had decided to take the treasure for themselves, he sent an assassin after them.'
âBut what about the map in Green's room at the Rattigan Club?' Ruby said. âIt showed three paths leaving from Rome.'
âI think Green's map was wrong. The brothers did take three separate journeys, but they went their separate ways from Delphi. Not from Rome. That letter from Quintus that Dr Serafini had at the Vatican showed they were all together when they left Rome for Brindisi. They were coming here.'
Ruby picked up a stick and traced a pattern in the dirt. âI like it,' she said. âIt answers all the questions.'
âSo you're descended from a bunch of thieves?' Sam said to Gerald. Then he shrugged. âI suppose you did grow up in Australia.'
Gerald smiled. âYou know what they say: you can choose your friends but you can't choose your relatives.'
He stood up and dusted off his backside. âThe three golden rods are the key. And for the first time since whenâ394AD?âthey're all together again. Charlotte has them and if she's not here somewhere already she can't be far away.'
âWherever she is,' Sam said, throwing the last of the pebbles into the bush, âI don't plan on meeting her with an empty stomach. Let's find something to eat.'
Gerald pulled Ruby to her feet and they took a last look at the Sanctuary of Athena, then set off to the village to the sound of birdsong, cascading water and Sam's rumbling stomach.
âW
ould it kill you to wash?'
A look of disgust spread across Ruby's face like an oil slick as Sam and Gerald pulled on the same shirts they'd been wearing all week.
âWhat's the problem?' Sam said, running his hands down his chest to flatten out the creases. âThis look fine.'
âIt's not the look I'm concerned about,' Ruby said, wrinkling her nose. âYou two really smell.'
Sam stuck his nose under his armpit and sniffed. âOnly to other people,' he said.
Ruby was dressed in a clean blue T-shirt and dark shorts that she had bought the night before. She had tied back her freshly washed hair and was stuffing dirty clothes into a laundry bag. âNico's aunt said she'd wash our clothes if we wanted. Last chance.'
Gerald and Sam looked at each other and shrugged. Ruby let out a weary sigh. âI'm living with pigs.'
âDon't worry about it,' Sam said. âIt's not like we can smell any worse.'
Over a breakfast of olives, feta and bread they decided that a trip to the town's museum might be useful.
âA bit of local history could fill in some gaps,' Ruby said.
Gerald rocked back in his chair. This whole adventure had started in a history lesson back in Sydney two months earlier. He shook his head at the memory of the daydream in Mr Atkinson's classâof fighting a shaggy giant who kept bellowing,
Nothing is certain!
Gerald stifled a laugh. He'd got that much rightâ nothing over the past two months had been even close to certain.
They stepped out into the morning sun. The day was promising to be a scorcher. Before they got down half a dozen steps, Nico had scampered to join them.
âI can show you the museum,' he said. âI know all the old stories.'
âI bet you do,' Ruby said. âYou're quite the tour guide.'
Nico gave an earnest nod. âYes,' he said. âI am.'
Sam tapped the boy on the shoulder. âHey Nico,' he said. âHere's another one for you? What's a Grecian urn?'
âI beg your pardon?' Nico said.
âWhat's a Grecian urn?' Sam asked again, his eyes sparkling.
Nico raised and lowered a shoulder. âIt is a largeâ'
âAbout twenty pounds an hour!' Sam slapped Nico across the shoulders and laughed.
Nico didn't miss a beat. âAgreed. That is what you will pay me for today's tour.'
Sam stopped laughing. âWhat? No, I didn't meanâ'
âIt is agreed,' Nico said with a note of finality.
âTwenty pounds an hour.' He then strode ahead, towards the Sanctuary of Athena.
âLooks like it's your shout today, Sam.' Gerald threw an arm over his friend's shoulders. âVery good of you.'
Sam's confused expression stayed with him until they reached the museum. It was a modern structure on the high side of the road, built into the rocky cliff. The occupants of half a dozen tour coaches milled around the forecourt waiting for the museum to open.
âThere are many visitors today,' Nico said. âIt would be better to visit the ancient city first, then the museum.'
âThere's an ancient city?' Gerald said. âNot just the sanctuary that we saw yesterday?'
âOf course,' Nico said. âThat is why the tourists are here.' He paused for a second, studying Gerald closely. âIsn't that why you are here?'
Nico stared into Gerald's eyes. Gerald could feel the gaze piercing his soul. He had to look away.
âOf course,' Gerald said. âLike you saidâwhy else would we be here?'
Nico looked at Gerald for a second longer, then he turned and led the way along a broad footpath beneath shady trees.
âDoes this kid ever smile?' Gerald whispered to Ruby. He held back a few metres to let Sam catch up with Nico for his latest attempt at a joke.
âHe's a curious one all right,' Ruby said. âWhy? You're not suspicious of him, are you?'
âNo, I guess not,' Gerald said. âHe's just a bit strange.'
Ruby looked ahead at Nico and Sam. She grunted. âNo stranger than most.'
They stopped in a small clearing just inside the entrance gates and bought their tickets. Nico cleared his throat and pointed to a path leading up a steady slope. âThe Sacred Way,' he said. âThis is where the pilgrims would walk to get to the Temple of Apollo.'
âWho's this Apollo, then?' Sam said.
Nico stared blankly at him. âDelphi is dedicated to Apollo. It was he who killed the giant python that lived in these rocks at the beginning of time. He was a god of many things: music, art, medicine. But mostly he was a sun god. He is usually shown with a bow and arrow. What is the word? Archer.'
Gerald's brain skipped a gear. âDid you say archer?'
âOf course,' Nico said. He pulled his ticket from his pocket and held it up. A colour illustration on the back showed an archer with his bow at full stretch against a blazing sun.
Ruby yelped. âThe Archer Corporation logo!'
Gerald stared at the ticket in Nico's hand. His great aunt had chosen a company logo with some history in mind.
âNico, was there some huge treasure here?' Gerald asked. âMaybe hidden in the temple?'
âOh, there was a very big fortune here,' he said. âBut it wasn't hidden.'
âWhat do you mean it wasn't hidden?' Ruby said.
âCome. I'll show you.' Nico started the climb up the Sacred Way. âDo you see the remains of all these buildings?' Both sides of the path were lined with the foundations of ancient stone structures. âAll of these were treasuries. Each from a different kingdom or region. They were filled with gold, jewels, pearlsâuntold wealth.'
âWhy would people send all that stuff here?' Sam asked.
âTo thank Apollo. This is where kings and princes would come to have their questions answered. Should I invade this country? When should I plant my crops? They would send riches as a show of gratitude. And they wanted their gratitude to be known by all, so it was displayed in these treasuries for the pilgrims to see.'
