tablet, roughly the size of a slim hardback novel. One corner had been broken off, but apart from some chipping and blotches of microbial growths the rest of it was intact. Several lines of text had been inscribed into its surface, but the elegantly curved script was completely unknown to her. ‘Gregor, Marco, look at this. Do either of you recognise the language?’ Neither did.
‘Tick tock,’ said Chase, pointing towards the surface. The level of illumination had visibly fallen. ‘We need to get back upstairs.’
Reluctantly, Nina put the tablet into the sample bag. ‘Mark the spot,’ she told Gozzi. ‘We’re definitely coming back here tomorrow.’
Chase entered the lab. ‘You coming for dinner? It’s after eight, and I’m starving!’
‘Shush,’ said Nina, flapping a hand. ‘I’m on the phone.’
‘Is that Eddie?’ asked an Australian voice from the speakerphone on Nina’s workbench. ‘How are you, mate?’
‘Hey, Matt,’ Chase replied, recognising their friend and colleague Matt Trulli. ‘I’m fine. How about you? I thought you were going to the South Pole or something.’
‘Yeah, in a week. Just got a few last-minute glitches to fix on my new sub; I’m waiting for the spare parts to arrive. Good job I caught the problem now - it’d be a bugger to fix in the Antarctic!’
‘I thought I’d take advantage of our tame nautical expert,’ Nina explained to Chase. ‘I was just asking him about the boat we found.’
‘Well, I looked at that photo you sent, and it’s definitely a lateen rig,’ said Trulli. ‘Triangular sail, invented by the Arabs. Something like the sixth century.’
‘BC or AD?’ Nina asked.
‘AD. Why, how old’s the site where you found it?’
‘Older.’
Trulli made an appreciative noise. ‘Another world-shattering discovery by Dr Nina Wilde, is it?’
‘Could be,’ said Nina, smiling. ‘Thanks for your help, Matt - I appreciate it.’
‘No worries - I’ll look in on you in New York when I get back. Oh, and consider this my RSVP to the wedding, okay?’
‘Will do.’
‘See you,’ said Chase as Trulli disconnected. ‘So, dinner?’
‘In a minute,’ Nina said, returning to her work. She held the clay tablet under a large illuminated magnifying lens, using a metal pick to remove the algae that a wash in distilled water had failed to shift. One particularly recalcitrant piece resisted even the pick; she used a spray can of compressed air to blast it with a fine astringent powder before switching back to her original tool. This time, the offending lump came free. ‘What’re they cooking?’
‘Eels.’ Nina shot him a dirty look. ‘How’s it going?’
‘Pretty well. I’ve almost got it cleaned up.’ She indicated the expensive digital SLR camera beside the waterproof camera she had used on the dive, a cable connecting it to her laptop. ‘I already sent some underwater pictures back to New York by satellite, but I thought it’d be easier for someone to identify the language if it wasn’t covered with crap.’
‘So you really don’t know? Guess you’d better withdraw that application to be the full-time boss of the IHA.’
‘It might be easier if I did.’
‘Really?’ Chase put a hand on her shoulder. ‘Hey, I was only joking. I thought you wanted the job.’
‘I do. But there’s just been so much bureaucratic and political garbage, especially over the last couple of months. It’s like everybody’s decided to gang up on me at once. Assholes.’ She let out a sigh.
‘I know what you mean. Every time I go through US customs now, I get the third degree from the immigration officers. Doesn’t matter that I’ve got a Green Card and a UN work permit - they treat me like the bloody shoe bomber!’
‘Yeah, you’d think they’d be more grateful, considering we saved the world.’ Nina took several photos of the tablet. ‘Maybe I should remind everyone of that, take up that offer to write my autobiography.’
‘You
