âAnd make it look like the city has been trashed and all the treasure stolen?' Ruby said.
âExactly. It's not like you'd need to take much care. It's meant to look like a ruin. That way when Quintus and the boys don't return to Rome and the emperor sends out a search party, it looks like they've stolen the treasure, torched the town and taken off.'
âWhen all the time the treasure is right here, just waiting for the three brothers to come back and take it.' Ruby tilted her head to the side. âNice theory.' Then her face turned dark. âBut what happened to all the people who lived here?'
Gerald breathed out. âMy guess is Quintus probably forced them to bury the city. Remember when Dr Serafini read that letter to the emperor. Quintus and his sons were due to meet up with a company of soldiers. They enslave the locals, get them to bury the city, create a fake Delphi, then,' Gerald paused, âthen kill the lot of them.'
Ruby gasped. âBut that would be thousands of people.'
Gerald closed his eyes. âI know.'
Ruby looked down at the statuette in her hands. âBut how would Quintus and his sons fool an entire company of soldiers? And if all the treasure is just laid out like this, what are the golden rods for? What do they unlock?' Ruby put the statuette back on its pedestal. âNice try, Gerald. But I think your theory needs some work.'
Nico and Sam appeared in the doorway. They both held blazing iron torches. Sam had a gem-encrusted crown on his head. âCome on you two,' he said. âNico's just had a brainwave.'
Nico's face was beaming. âThese are the treasuries,' he said, indicating the line of buildings they had been exploring. âThe real prize must be up this way.'
âWhat?' Gerald said. âEven more of a prize than this?'
âOf course,' Nico said. âThe Temple of Apolloâand the inner sanctum of the Oracle herself.'
Sam slid his crown to the back of his head. âThen lead the way, Nico. If it's more impressive than this lot, it's something I want to see.'
They climbed a set of stairs onto a terrace cloaked in shadow. They stopped at another lamppost, this one taller than the others and with three lanterns at the top. Nico broke the seal on an oil pot at its base and he and Sam emptied the contents into a well in the centre of the pillar. Nico squinted into the narrow opening.
âOne more perhaps?' he said to Sam, and they poured in a second pot for good measure.
âThis should keep it going for a while,' Nico said.
Sam struck the flint and the three lanternsâ
pop,
pop, pop
âflared into life. Then, a second later, a colossal burst of light erupted to their left. A string of three-headed lampposts ignited in a chain reaction across the terrace, pouring out a wave of light that rolled over them and the exterior of the Temple of Apollo.
The darkness fell away as if someone had opened a curtain onto a sunny day.
âHoly cow!' Sam said. âThat is
awesome
.'
Gerald could almost hear a choir burst into song.
It was the most breathtaking sight.
Marble columns lined the outside of the long rectangular temple. Gold inlay glistered in the lamplight and brightly painted friezes capped the roofline. Standing to their right, across the terrace, was a colossal bronze statue of a man at least fifteen metres tall draped in silk. In one hand he held aloft a blazing lantern, the brightest point of light in the underworld. In the other hand was a bow and arrow.
âApollo!' Nico said. âThe archer.'
A shiver ran the length of Gerald's spine, then turned around and scuttled back the other way. Things seemed to be getting very close to home.
Ruby appeared at his elbow, holding two blazing torches. âCome on,' she said. âLet's see what's so special about this temple.'
The four of them approached the temple steps in a line. Columns towered above them and Gerald had a flashback to walking into the British Museum for the first time just eight weeks ago.
They entered the portico. The doors to the templeâ two enormous wooden portalsâstood closed before them. Gerald was so transfixed by the majesty of everything around him that he didn't see the slab of white marble jutting up from the floor. He stubbed his toe, hard.
âOw!' he cried, hopping on one foot and holding back the stream of swear words that flooded his brain. âWhy would you leave that in the middle of the floor?'
He pointed his flaming torch to the ground. The slab of white stone was about a metre square and lay right in front of the temple doors.
âLook,' Ruby said. âThere's something carved into it.'
She moved her torch in closer. The flickering light waved across letters chiselled into the polished surface.
It read, in clear English,
Gerald Wilkins, welcome
.
G
erald stumbled backwards, almost falling to the ground. Ruby stared at the slab in astonishment. âHow did that get there?' she said.
Gerald gazed dumbly at the letters carved into the stone.
âHow could anyone know you'd be coming here?' Ruby said. âThis place has been deserted for more than a thousand years.'
âIt's fate,' Gerald muttered. âSomeone must have known.'
âRubbish!' Ruby said. âIt's just aâ'
âCoincidence?' Gerald interrupted. He took Ruby by the wrist and pulled her torch down until the flames licked across his name on the slab. âEven this must be too much for the coincidence queen to write off as just one of those things. Two turns around the table in London didn't stop me from seeing this, did it? So much for the chaos theory. So much for
nothing is certain
. This looks pretty certain to me.'
Ruby dropped to her knees and ran her fingertips across the chiselled letters of Gerald's name. âBut if this was carved all these years ago, how would they know how to speak English? Wouldn't it be Greek?'
âThe Oracle,' Nico said. âIt must have been the Oracle.'
âShe could speak English?' Sam said.
Nico shook his head. âThe Oracle would go into a trance and communicate directly with Apollo,' he explained. âThe temple priests would write down the responses, even if they didn't understand them.'
Ruby snorted. âSo Apollo was dictating? He told her to expect a visit from a Gerald Wilkins in about sixteen hundred years and she'd better put the kettle on? That's ridiculous.'
Gerald tapped his foot against the marble slab. âWell, it's a tonne of ridiculous, whatever it is.'
âIt's signed,' Ruby said.
There was a dull silence.
âWhat did you say?' Gerald asked.
âI said, it's signed. The Oracle's name is at the bottom.'
âWell, that'll come in handy if I happen to bump into her down here. What's her name?'
Ruby swallowed. âIt'sâ¦Clea.'
âClea!' Gerald said. âThe same name as my dad's cousin? The captain of the parlour game goon squad?' He raised his head to the ceiling. âSo that's just another coincidence, is it Ruby?'
Ruby took in a sharp breath. âOh my gosh, Gerald.'
âWhat now?' Gerald asked.
âYour family tree from Mason Green's room in the Rattigan Club.'
Gerald furrowed his brow, remembering the diagram of his family tree scrawled across the wall in Green's private rooms. It seemed so long ago.
âWhat about it?'
âEver since we met your dad's cousin that night of the party, something has been bugging me. Don't you remember? The family tree showed your mother's family, all the way back to Quintus Antonius and his three sons.'
âYeahâthat's why we're here,' Gerald said.
âWe've been concentrating on them all this time: the secret mission for the emperor, the three caskets, the assassin sent to hunt them down.'
âSo?'
âBut what about your father's side of the family? Think about what was on the wall at the Rattigan Club. Your dad's family traced back to one woman.'
Gerald focused his mind. He saw his father's name written on the wall, then lines and names branching back through the generations, and finally homing in on a single name.
âClea!'
Gerald stared with saucer eyes at the writing on the marble slab.
Clea.
Was he a direct descendant of the last Oracle of Delphi; the same woman that his mother's ancestors had been sent to destroy?
âYou
are
the progeny!' Ruby jumped up and grabbed Gerald by the arm, her excitement flowing through her touch. âThat's what the fortune-teller in India told you. He saw it in you. After sixteen hundred years, the two sides of this puzzle have come together. Your blood flows from the Oracle of Delphi, and from the emperor's right-hand man.'
Gerald tried to keep the curdling feeling in his belly from erupting into his throat. âProfessor McElderry said something about the progeny at the fancy dress party,' Gerald mumbled. âSomething about a family legend.'
âOf course!' Ruby said. âThe big family secret that Mason Green kept banging on about. I bet that's why you had those visionsâin the museum, and in Mr Hoskins' bookshop in Glastonbury. Somewhere deep inside you, Gerald, lies the power of the Oracle.'
Gerald stared again at his name in the white marble. A name carved in antiquity. He thought back to the golden rods, and the gems that had kept them locked away in the caskets. Of the visions he had experienced when under their spell. The sensation of being everywhere, of seeing everything.
Of having the power to see all that would be.
The power of an Oracle.
âWhat am I supposed to do?' Gerald looked Ruby square in the eyes. His voice quavered. âWhat am I supposed to do?'
Ruby reached out to Gerald's shaking hands.
âThe door's open.' It was Sam. He and Nico were standing at the temple entrance. One of the enormous portals stood ajar.
âHow did you manage that?' Ruby asked.
âUm, I just sort of leaned against it and it moved,' Sam said. âWant to take a peek inside?'
Gerald looked to Ruby. She gave him a reassuring nod. âLet's do it,' she said.
Two torches flamed above the entrance, on either side of a large block of marble. Some script in Greek lettering was carved into the stonework. Ruby nodded towards it. âNico, can you read that?'
Nico gazed at the lettering. âOf course. It says
gnothi
seauton
â'
Gerald came to an abrupt halt.
âDid you just say
nothing is certain
?'
Nico looked at him, confused.
Gerald advanced on him. âDid you just say
nothing
is certain
?' He was almost shouting at Nico.
Nico stared up at Gerald.
âAnswer me!' Gerald's face was flushed and the torch light cast deep shadows under his eyes.
âSteady on, Gerald.' Sam moved to Nico's side. âHe's just reading what's there.'
âThen he can tell me if it says
nothing is certain
.' Gerald's voice verged close to hysterical. âThat phrase has been dogging me since the last day of school and I want to know if somebody carved it here two thousand years ago.'
Nico cleared his throat. âIt says
gnothi seauton
. It is a Greek saying.'
Gerald was breathing hard, his temper bubbling under his skin.
âIt means
know thyself
,' Nico said calmly. âIt is the most famous of the seven maxims that were said to be carved in the temple walls.'
Ruby grabbed Gerald and pulled him away. âWhat's the matter with you?' she said. âWhy are you yelling at Nico?'
Gerald clenched a fist against his forehead, punching himself. âIt sounded like he said
nothing is certain
. You don't understand. It was in a daydream I had at school. Then the fortune-teller in Delhi said it. Maybe I heard it wrong. But it's doing my head in. This whole Oracle thingâ¦it feels like my brain is about to explode.'
Ruby squeezed Gerald's arm. âWe've come a long way, Gerald,' she said. âYou know I'm with you on this. No matter what.'
Gerald's eyes were closed. He breathed deep, and nodded.
âWe can't be far from whatever's at the centre of all this,' Ruby said, her voice a balm. âLet's just keep going.'
Gerald opened his eyes to find Ruby staring at him. The corners of her mouth tweaked upwards.
Gerald apologised to Nico and the four of them crossed the threshold into the Temple of Apollo.
The interior was lit by a string of oil lamps that ran the length of the ceiling high above.
âThat's one impressive lighting system,' Sam said. âIt must all be connected to that lamp out the front. You Greeks were pretty clever, Nico.'
âWe still are,' Nico said.
The temple was one enormous chamber filled with shrines and offerings to Apollo. Rich tapestries hung from the ceiling, gold and silver statues stood atop marble plinths and murals of Apollo's heroic deeds covered the walls.
