Parking anywhere near the centre of Oxford was always a challenge, but Pelham finally found a space in a residential street where he barely had to nudge the cars either side. They walked briskly and found Albie waiting by a side door of his college, pacing back and forth, checking his watch. ‘This better be important, Olivia,’ he said, kissing her briskly on the cheek. ‘I’m supposed to be giving some wretched talk.’
‘It is important,’ said Olivia. ‘And we’re terribly grateful.’
He waved them inside, then led them with the cautious stoop of a tall man in an old building. They reached a stock room. He gave a courtier’s wave at the array of remote-sensing devices on the shelves and slouched like problem youths against the facing wall.
‘You’ve got a Mala!’ said Rachel, going straight to it. ‘Fantastic.’
Albie winced. ‘Our moon-buggy is a fine machine too,’ he said, steering her towards its neighbour. ‘A real workhorse.’
‘We’ll look after it, I swear,’ promised Olivia. ‘We’ll bring it straight back.’
Albie sighed. ‘Tomorrow will be fine,’ he said, as Luke and Pelham gathered up the Mala and its peripherals. ‘So what are you looking for?’
‘I can’t say,’ Olivia told him. ‘Really, I can’t. But if we find anything, you’ll be the first to know.’
‘I should damned well hope so.’
The old Ashmolean was closer than the car, so they headed straight there. Their route took them past the Sheldonian. ‘Maybe it wasn’t the alchemists’ network,’ mused Olivia, frowning at it. ‘Maybe it was this guy.’
‘You mean Wren?’ asked Rachel.
Olivia nodded. ‘One of Newton’s closest friends. One of Ashmole’s, too.’ Her museum was bang next door. ‘There’s even a suggestion he may have helped design this place,’ she said, leading them up its front steps. ‘At least, that’s what we tell people.’
Rachel smiled. ‘Must add a bit of cachet.’
‘And makes it harder for the council to tear us down.’ She unlocked and opened the door, turned off the alarm, switched on lights. They found themselves in a display gallery that also served as reception and gift shop. An internal staircase led both up and down. They went down, passed through more doors into a large display room crowded with neat ranks of glass-topped display cabinets, and with sundials, grandfather clocks and other large chronometers against its walls. ‘Conrad said it was in here,’ she said. ‘I don’t know exactly where.’
‘Great,’ said Rachel. ‘Then let’s start looking.’
