THE SAFE PLACE

'WE ARE HERE.' Sinamoi, with Xian Mei in tow, had led them through the potentially treacherous resort on a circuitous route, avoiding the main thoroughfares where the tourists hung out and sticking to hidden paths and back alleys.

Although Purna, Sam, and Logan had followed him without question, Purna, in particular, had remained wary, constantly alert to the fact that, for whatever reason, their guide might be deceiving them or leading them into a trap.

They had seen one or two zombies wandering about but had managed to remain out of sight and undetected.

'Very quiet now, but tomorrow this will not be a good place,' Sinamoi hissed at one point, after they had lain low for a couple of minutes while a clearly infected black man – scrawny, old, and white-bearded – had shambled past, snarling and twitching.

They finally emerged from a winding, tree-shrouded path to find themselves on the main route down to the shore, though it was evident from the way the soughing of the waves had been growing steadily louder over the past ten minutes that this was where they had been heading.

Purna half expected to see the lights of a boat twinkling out on the black water, ready to whisk them away, but instead, Sinamoi led them to a grey one-storey building with barred windows, squatting on the dunes that overlooked the powder-white beach.

'What's this?' she asked.

'Lifeguard station,' Sinamoi replied. 'Very strong building. Very safe.'

'How do we get in?' Sam wanted to know.

Sinamoi grinned, reached into his pocket, and produced a key. 'I am a lifeguard,' he said.

He unlocked the door, and they went inside. The station was well equipped with tables and chairs, a two-way radio, and even a small camping stove.

There was all-weather gear hanging on hooks on the wall, a metal first-aid box the size of a small suitcase, and a camp bed in one corner.

Sam nodded at the camp bed. 'You live here?'

Sinamoi laughed, as if Sam had made a joke. In his broken English, he explained that one of the duties of the lifeguards was to stay in constant touch with the fleet of offshore fishing boats, which operated out of Moresby harbour.

If a boat got into difficulties, it was the responsibility of whoever was on night-duty to alert the other lifeguards so that a rescue boat could be launched.

'And it's your turn now, huh?' said Logan tiredly, looking drawn and exhausted.

Sinamoi nodded and grinned.

'So who told you to come looking for us?' asked Purna.

Sinamoi pointed at the radio, which was scratched and battered with chunky, old-fashioned knobs and dials, and headphones that looked as though they were held together with heavy-duty parcel tape.

Happily crackling and buzzing away to itself, it looked like the sort of lash-up you only ever saw these days in old war movies.

'Man on the radio,' he said. 'He tries to …' He imitated holding a cell phone up to his ear.

'To call us?' said Sam.

'Yes. But signal gone. So he calls me. A much stronger signal.

Promise me much money if I bring you here.'

'Did he now?' said Purna. 'And did he say why he wanted you to bring us here?'

'To keep you safe.

Also, he has a message.'

'What message?'

Sinamoi frowned. 'He says go inland. Past the jungle to the other side of the island. Go to the prison island. Top of the tower will be a helicopter. It will fly you away.'

'Is that all he said?' asked Sam.

Sinamoi nodded. 'Yes. Except he tries to call if he can.' He mimed holding up a cell phone again.

Sam sighed. 'You ever spoken to this guy before, Sinamoi?'

The lifeguard shook his head. 'No.'

'So you've no idea who he is?'

'No. But he wants to save you. So is a friend, yes?'

'I hope so,' said Sam. He propped his weapon against the wall, pulled a chair out from under the table, and sat down with a grunt. 'Wish we knew who he was, though.'

Following his example, Purna and Logan also laid their weapons aside. Purna sat down too.

'I've got a few ideas,' she said.

'Care to share them with the group?'

'Sure. I could do with cleaning up a bit first, though, and we could all do with a drink. Need to keep our fluids up. Sinamoi, you got any water?'

The lifeguard nodded eagerly. Crossing the room, he pushed aside the all-weather gear to reveal a door, behind which was a tiny cubicle containing a primitive toilet and washbasin.

'Much water.

But this no drink.'

He put a hand on his stomach and stuck out his tongue, miming sickness. Then he crossed to the workbench on which the radio sat, knelt down, reached underneath it, and dragged out a plastic, almost full five-litre water container.

'This drink,' he said. As he poured water into a variety of chipped and grubby-looking mugs, Purna went into the toilet cubicle to clean up as best she could.

Accepting a mug of water, Sam looked at Logan, who was slumped against the wall. 'You look wasted, man.'

'I feel it,' said Logan. Turning to Sinamoi, he flipped a thumb towards the camp bed and said, 'Hey, mind if I crash a while?'

Sinamoi nodded vigorously. 'Rest. Sleep.' Then his brows beetled in concern. 'You sick?'

'Just tired,' said Logan. 'Lost some blood.'

He glanced at Sam, who was staring at him intently and raised his right hand. 'On my honour, man. It's not the fucking virus. I've got no designs on your black hide.'

Unexpectedly Sam grinned. 'Think you'd find my meat a little too refined for your palate anyway, white boy.'

Logan chuckled, trudged across to the camp bed, and all but crumpled onto it with a groan.

'You need medicine?' said Sinamoi.

'Sure,' said Logan wearily. 'I'll take anything you got.'

Five minutes later, dosed up on painkillers, he was snoring quietly in the corner, mouth open. Sam, Purna, Xian Mei, and Sinamoi were sitting around the table, hands curled not round mugs of water this time, but hot black coffee.

Sam blew on his coffee before sipping it, then sat back with a sigh. Although he normally took his coffee with cream and sugar, he murmured, 'Man, that's the best cup of coffee I've ever tasted.'

Purna turned to Xian Mei, who so far had barely said a word. 'So what's your story?' she asked.

Xian Mei looked defensive. 'What makes you think I have one?'

Purna nodded at Sam, then over at Logan asleep in the corner. 'I can see the connection between the three of us, but you're the odd one out; the unknown quantity.'

'You mean the blood drive?' said Sam.

'Yes. We're all here because we gave blood and won ourselves holidays in Banoi. It, therefore, figures that our mysterious caller is something to do with the NBDC.' She stared at Xian Mei, narrowing her eyes. 'But who are you? His spy?'

Xian Mei tried not to react, even though the Australian girl had come startlingly close to guessing the reason she was here. Matching the girl's intense stare with one of her own, she said firmly, 'I'm nobody's spy. Maybe I was included because I gave blood too.'

'You did?' said Sam, surprised.

'In which part of the US?' asked Purna.

Xian Mei shook her head. 'Not in the US. In China.'

'China?' said Sam. 'I thought this blood drive campaign was an American thing?'

Xian Mei shrugged. 'There was one in China too. But it was organized by the Chinese government.'

'Or at least, that's what you were told,' said Purna.

'What do you mean?' asked Sam.

'Think about it. Logan got bit. Xian Mei got bit. We've both been sprayed with zombie blood, which means we've almost certainly ingested some – but none of us is infected.'

Sam frowned, assessing the implications of her words. 'You mean we're immune?'

'Not only that, but the NBDC, or whoever's behind this thing, knew we were immune before we came here. That's the reason we are here. It's not random chance. Our names weren't drawn out of a hat. It's because of our immunity.'

Sam's eyes widened as the terrible truth dawned on him. 'But that means …'

Purna nodded grimly. 'It means that whoever sent us here knew about the virus before we arrived. It means they knew this was going to happen.'

Xian Mei shook her head. 'No.'

Purna looked at her sharply. 'What do you mean, no?'

'I mean that whoever is responsible for us being here didn't simply know that this was going to happen. That's too much of a coincidence.'

'Fuck, you're right,' said Purna.

'You mean they did it deliberately?' muttered Sam. 'They created it?'

Both girls nodded in unison.

'But why?' Sam asked.

Xian Mei shrugged. 'To use as a weapon? Biological warfare?'

'Motherfuckers,' snarled Sam. 'So why throw us into the mix?'

'As guinea pigs?' suggested Purna. 'To see how immune we really are? They've already got our blood, remember, so we're expendable.'

'The question is,' said Xian Mei, 'is our mysterious caller working for the people who put us here or working against them?'

'So what we talking about here?' asked Sam. 'Rival governments?'

Purna spread her hands.

'Who knows? Our guy could be appalled by the fact that we've been thrown into the lion's den and is genuinely working in our best interests by trying to get us out, or he could be working for an enemy government that wants to develop a vaccine from our blood in case the virus is used against them.'

'Or maybe he has a different agenda entirely,' suggested Xian Mei.
