‘Sir Isaac Newton,’ murmured Rachel, reading the inscription.
Luke glanced down. Curiously, unlike on the first two walls, the inscription didn’t look quite centred, but was offset a little to the left instead.
Rachel now read out its lower line. ‘BH 01256.’ She gave a sigh. ‘So much for my initials and date theory.’
‘Maybe it’s a cipher of some kind.’
‘Saying what?’
‘I don’t know. It’s in cipher.’
She laughed and gave him a playful slap. ‘I thought maybe you’d know the kind of ciphers these guys used.’
He shook his head. ‘Olivia might. Or my mate Jay. Newtonian ciphers are right up his street.’
‘And he’s in Oxford, is he?’
‘London.’
‘That’s helpful, then.’
They moved to the next wall. Another portrait. ‘John Evelyn,’ read out Rachel. ‘The diarist, right?’
‘Among other things,’ said Luke. Like so many notables of his era, Evelyn had been a polymath: a pioneer in horticulture, medicine and city planning, and one of the driving forces behind the Royal Society. He had a line of cryptic characters beneath his name too. BC 10484. Luke crouched down and ran his finger over them, as though touch might reveal their secrets, like Braille. But all he got was dust. He stood again, looked around. Someone had gone to extraordinary lengths to build this place and make a gallery of its walls. Yet they’d also bricked it up and hidden it down a well shaft so that no one would ever know it was here. Why?
Rachel was already on the next wall. ‘Sir Christopher Wren,’ she said.
‘Makes sense,’ nodded Luke. ‘He wasn’t just mates with Newton and Ashmole, but with Evelyn, too.’
‘So he links them all together.’ She stooped to read out the cipher. ‘KD 11201,’ she said, glancing up in case inspiration had suddenly struck. He shook his head.
They went together to the last two walls, a double-width panel showing a single scene: a great tower at the heart of a walled courtyard. ‘What the hell?’ asked Rachel.
‘The Temple of Solomon,’ said Luke. ‘Taken from one of Newton’s own drawings, I think.’
‘Newton drew Solomon’s Temple?’ frowned Rachel.
‘He was one of the world’s great experts,’ Luke told her. ‘He wrote a famous treatise on it. At least, it was ostensibly about the Sacred Cubit of the Jews, but in truth it was about the Temple. It needed to be rebuilt for the Second Coming, you see, and as the Bible gave its measurements in cubits, you had to know how long a cubit was, or you’d build it wrong. And who better to get it right than Isaac Newton, old
‘And these other guys? Wren and Evelyn and Ashmole? Were they Temple geeks too?’
‘Wren was,’ said Luke. ‘A couple of days after his daughter died, he got blitzed with Robert Hooke and spent the whole night talking about the Temple. And Evelyn would have known it as well. The Temple had been designed by God, you see, so it was, by definition, perfect. Any city planner worth his salt had to be familiar with it.’ He turned the lamp back on the first wall. ‘And it ties into that, too. Solomon’s Temple is the basis of Masonic lore.’
‘Olivia said Ashmole was a Freemason,’ said Rachel. ‘And you said there were rumours about Newton. What about the others?’
‘I don’t know about Evelyn, but Wren for sure. Freemasonry came out of the construction industry, remember, and London was the construction capital of the world at the time, thanks to the Great Fire. And guess who was responsible for commissioning all the main work?’
‘Don’t tell me: Sir Christopher.’
‘They say he was the number two Mason for a while,’ said Luke. ‘And the first Grand Lodge met bang next door to St Paul’s Cathedral. There’s even a plaque to it.’
Rachel sighed deeply. ‘So what is this place? A monument to these men?’
‘Not
‘Here,’ said Rachel. Some lines had been inscribed in a panel of green marble halfway along the plinth’s side. He crouched beside her to read them.
‘St Paul on the road to Damascus,’ said Rachel. ‘I wonder if there’s another on the other side.’
They went around to check and were rewarded.
‘The Emerald Tablet,’ murmured Luke.
‘What on earth’s it doing here?’
He shrugged. The Hermetic texts had caused intense excitement when they’d been discovered during the Renaissance. People had believed them written in deepest antiquity, perhaps even at the time of Moses himself. Their prestige had faded, however, once they’d been correctly dated to the early centuries AD. Yet alchemists had continued to revere them, especially this particular text. Newton had been so intrigued by it that he’d even studied Arabic in order to make his own translation.
Rachel raised an eyebrow when Luke told her this. ‘Is this his?’ she asked.
‘No. But I think it’s based on his. Just a lot shorter.’
Rachel sighed and shook her head, then she stood and worked her spine. ‘Pelham and Olivia will be having kittens,’ she said.
‘Yes,’ agreed Luke. ‘It’s time we were getting back.’

Walters had just reached the outskirts of Oxford when Croke called to let him know they’d come up dry in Crane Court and were switching their search to the old Ashmolean instead. ‘What do you want us to do?’ he asked.
‘Hold off,’ Croke told him. ‘We’ll be coming down ourselves. We’ll take care of everything.’
‘Including Luke and the others?’ asked Walters. ‘Only they can cause us real grief, remember?’
‘I’m well aware of that, thank you. And I said I’ll take care of it. Anyway, it’s too late for you lot to do anything. My friends already have the place surrounded.’
‘Whatever you say.’ Walters ended the call and drove up Broad Street all the same. Sure enough, there were dark figures in a pair of cars parked across the road from the museum, and strange shadows in nearby alleys.
