It was all Alison craved. A return to normality, a happy united family. So where was she? Where could Ruby be – today of all days? Should she call Jonathan? Get him to come over? No, best not give him any more ammunition when the truce was so fragile.

Ruby’s year-long exile from the family had been awful. Not just the bitter accusations, the tears, the threats, but more the sheer lack of her, their eldest, at family gatherings, holidays, barbecues. It had all just felt wrong, as if they – and she – were somehow wilfully ignoring a burning building or drowning swimmer.

Alison stalked through the flat again – bedroom to bathroom to living area – but there was no sign of her. What was this? A final act of rebellion? A warning that she could – and would – still be her own woman? Or was this something more serious? Was she reneging on their agreement? The uncertainty made Alison deeply nervous.

Then suddenly, birdsong – Alison’s phone heralding the arrival of a new tweet. Ruby was a regular tweeter – it was largely how Alison kept tabs on her – so Alison rushed over to her bag, pulling out the contents in search of her phone.

It was from Ruby. Alison read the tweet. Frowning, she read it again. She couldn’t be that selfish, could she?

‘Need to get away and be by myself If people had loved me better then I would stay … Rx’

She could. Ruby had pulled the roof down on them. And Alison knew immediately there would be no coming back from this.

Having finished tweeting, he turned the phone off and stowed it safely in his jacket pocket. He checked again that the coast was clear, but he was being over-cautious: no one penetrated this deep into the forest.

Pushing on, he made his way slowly through the undergrowth, careful not to snag his clothes on any of the thorns or brambles. His synthetic clothing was unlikely to leave any fibres behind, but you could never be too careful.

He emerged into a small clearing. The foliage was less thick here, the soil sandy and dry. Perfect for his purpose. Clearing a small patch of vegetation, he retrieved the large bundle of sticks from his rucksack and laid them carefully on the ground. Soon he had a good pile, encircled by the little trench he had dug carefully with his trowel. The trench would catch any stray sparks – a forest fire here would be catastrophic. Safety first, always safety first.

A little crumbling of firelighter to set it going. This was more dangerous than using newspaper of course, but newspapers could provide useful clues to a half-intelligent police officer, so paraffin it was. It seemed odd to feel the heat of the fire on an already warm Saturday afternoon, but needs must. If anyone did see it, they would think it was holidaymakers having a barbecue – there were loads of them about at this time of year. Anyway, he’d be long gone by the time anyone did find it, so …

The thought of discovery, as ridiculous as it was, prompted him to action. He pulled Ruby’s pyjamas from the bag and laid them on the fire. He watched them burn, riveted by the slow conflagration. They resisted stubbornly at first, then came the first flicker as the fibres began to catch, before eventually they succumbed to the inevitable.

It was stupid to enjoy it as much as he did. But he couldn’t help it. It was beautiful – the leaping flames, the glowing embers and finally the gossamer soft ash. He was moved by what he saw, aware of its wonderful significance. This was the end of Ruby. She was dead and gone now, but from the fire, from the ashes, something new and beautiful would rise.

The young woman lay cold and lifeless on the slab. The sand that had encased her for so long had been swept away grain by grain and sent for analysis, leaving the victim looking strangely clean. Now that she was away from the beach, exposed and unadorned in the police mortuary, she was a pitiful sight. She was so thin – skeletal was how Jim Grieves, the pathologist, had put it over the phone. As Helen stared at the corpse, she felt a wave of nausea sweep over her. This had once been a vibrant young woman, but now her skin was grey, her lips cracked and her bones strained everywhere to puncture what remained of her skin. Helen felt profoundly sorry for her.

They had searched the Police National Computer and made the customary missing persons enquiries, but had come up with nothing. So Helen had decided to head straight to the police mortuary to see if Jim could throw any light on who she was and how she had come to this.

‘She’s been starved,’ Jim offered as his opening salvo. He was not without compassion, but he was to the point, years of service and hundreds of corpses having eroded his desire to engage in pleasantries. ‘Her stomach has shrunk to the size of an orange, bone strength has been compromised and I found traces of non-edible objects – wood, cotton, even metal – in her digestive system.’

Helen nodded.

‘I’ve more work to do, but so far I can find no obvious cause of death. The neck and vertebrae are intact, there are no bullet or knife wounds, no signs of manual or ligature strangulation either, so for now we’ll assume that she starved to death.’

‘Jesus.’

‘This would fit with a few other things I’ve observed. Her skin has a grey, leathery quality – even where it has been well preserved – and her eyes have deteriorated markedly. I would say she was virtually blind by the end. Also, bloods show that she had a total absence of vitamin D in her system.’

‘Meaning?’

‘Taken all together it suggests that she was kept in total darkness in the final weeks or even months of her life.’

Helen couldn’t find words to express her horror this time. Had this young woman starved to death in a lightless hell?

‘Anything else?’ Helen said quickly.

‘You’ll note the tattoo – a bluebird on the right shoulder – done sometime in the last three to five years. Also, the pitting around the groin area. Looks like historic evidence of an STI – I would hazard molluscum contagiosum, but I’ll confirm when I’ve done more tests.’

‘How long has she been buried?’

‘Hard to say with any real accuracy. As you can see, the body has started to decompose. Skeletalization is about thirty per cent complete but there is still plenty of skin remaining and the hair is largely intact. Heat speeds up decomposition, cold slows it down and it was pretty chilly down there. So I would estimate two to four years.’

Helen exhaled – those parameters were too broad for her liking.

‘But I do have something else that might help,’ Jim continued. Turning, he offered Helen a small metal bowl. Helen peered into it – a small, electronic device lay inside.

‘Your victim had a heart condition. This is her pacemaker,’ Jim explained, wiping rust and dried blood off the unit, ‘complete with manufacturer’s logo and serial number.’

Helen mustered a half-smile: finally some good news.

‘Run that serial number down,’ Jim continued ‘and you’ve got your girl.’

DC Sanderson approached the flat in Millbrook with a heavy heart. Increasingly this was her lot in life – sweeping up the cases that no one else in the Major Incident Team wanted. Helen, Lloyd and a number of the others had been out at Carsholt, doing the interesting stuff. What had they left her? A glorified missing-persons case. She didn’t blame Helen, who had always treated her fairly and encouraged her as a fellow female officer. No, she laid the blame squarely at Lloyd Fortune’s door, who she felt favoured the new DCs over her. It wasn’t fair – she was more experienced, knew Southampton better than these blow-ins – but station politics is a fickle business.
