Grounds for Appeal (3 page)

Priscilla looked from one to the other. ‘I'd love to – but I really think I should get back to London and keep looking for a job in archaeology. That's where most opportunities are likely to arise.'

She had been lodging in a bed and breakfast in the village half a mile away and, though it was quite comfortable, she missed the bustle of the metropolis, unlike Richard and Angela, who had settled happily into these beautiful rural surroundings.

Since they first moved in the previous May, they had lived together in the big house, no doubt giving ammunition for the village tongue-waggers in Tintern Parva, just down the valley. However, the arrangement had remained professional and platonic, though there had been a couple of occasions when the conventions had been a little strained.

Angela and Richard were equal partners in the venture, as when they had set up their partnership earlier that year, Richard contributed both his golden handshake from Singapore University, where he had been Professor of Forensic Medicine, as well as the house he had been left by his aunt. On her part, Angela had put the proceeds of the sale of her London flat into the pot and with the added help of a modest mortgage, they had raised the capital needed to make some alterations to the rooms and equip the laboratory.

‘Then stay until the end of this month, at least,' suggested Angela and, without more persuasion, her friend agreed to remain for a couple more weeks.

When their business discussions were done, Richard told Angela of current cases and especially the odd request he had had from Cardiganshire about the alleged ‘bog body'. Like Priscilla, his partner knew quite a lot about the finds reported in Denmark and elsewhere, which were obviously of considerable interest to all forensic biologists.

‘Let's see tomorrow whether it's a sheep or King Arthur!' said Angela, happy to be back in harness herself.

The tests next day confirmed that it was not a sheep and, at a stretch, it could be King Arthur, for at least it was human.

At about ten o'clock next morning, a Triumph motorcycle roared up to the house and a helmeted police officer handed over a small package in return for a signature on his exhibit docket. Richard was due to go down to Chepstow to carry out a couple of routine post-mortems for the coroner at the public mortuary there, but he could not resist waiting to have a look at the specimen. The others crowded around, even Moira, who left her typewriter to have a look at such a curious sample.

Richard took the small glass bottle from the plywood box that protected it and found a sheet of paper wrapped around it. It was a note on Home Office letter-heading from Philip Rees, one of the forensic scientists at the Cardiff laboratory, whom they had met in a case a month or so earlier.

‘It just says that they did a precipitin test and it was unequivocally human tissue,' he announced. ‘He also says there's a small piece of cord as well, but they did nothing with that, as they were only asked to carry out a species identification.'

He peered into the bottle, then handed it to Angela, who diplomatically gave it to Priscilla to deal with. With the others watching, she carefully slid the contents out into a shallow glass dish. A greyish cylinder sat there, with a leathery cap. A short length of thin cord lay alongside it.

‘Not very exciting, is it?' said Sian. ‘Looks like a lump of dirty candle grease.'

Richard picked up the dish and held it to his nose. ‘Adipocere, as I suspected from the story.'

He then had to explain to Sian and Moira. ‘When body fat is left for a long time in moist surroundings, it's often converted into a kind of soap, which can persist for centuries. But bog bodies are usually around two thousand years since death and I just don't know if adipocere would last that long.'

‘What about the scrap of string?' asked Priscilla.

Richard shrugged. ‘I'll leave that to you clever ladies. If we confirm it is human – and I've no reason to doubt Cardiff – then there'll have to be an exhumation. Maybe then the reason for the string will become clear.'

‘What about that dark bit on top of the fatty stuff?' asked Priscilla.

‘Could be skin, I suppose. Can you snip a bit off one edge and give it to Sian to process for histology? We can have a look under the microscope then, see what the structure is like.'

He looked at his watch and hurriedly left for his post-mortem session. Angela, not wanting to appear as if she was supervising her friend, left to do her unpacking upstairs and Moira drifted back to the office before starting on lunch, as her duties included making a light meal for the doctors at midday and something more substantial in the evening. Cleaning, washing and bed-making were now the province of the appropriately-named Mrs Daley, from the village.

Sian began processing the skin fragment by dropping it into formalin, then had some spare time. She wandered over to Priscilla and watched her deft fingers manipulating small pipettes and a rack of narrow tubes. Sian marvelled at how she could keep her long red-varnished nails so perfect when handling glassware and chemicals.

‘What exactly is this test?' she asked. ‘I've heard of it, but I'm not quite sure how it works.'

‘It's been around for ages,' answered the biologist, always happy to instruct. She pointed to a rack of labelled vials, taken from the refrigerator. ‘These are made from the blood of rabbits immunized with sera from different animals, including humans. A small quantity is injected, which doesn't hurt the rabbit, but stimulates the production of antibodies specific for the proteins of that particular beast.'

Sian nodded, she knew about antigen-antibody reactions from her time in the hospital laboratory.

‘How do you get a result, then?'

‘Basically, an extract is made from the test sample and layered on top of each specific serum in a tube. If an antigen for a particular species is present, then a white line appears at the junction between the two fluids, due to protein being precipitated.'

She added small amounts of the fluids into a series of tubes as she talked. ‘In this case, I'll have to get rid of all this fat first and get a clear solution. Let it incubate for a few hours and see what happens. Naturally, we have to set up controls and blanks to make sure the result is genuine.'

It was the afternoon before all this was done and Priscilla was able to confirm that the substance was definitely human in origin by the time they assembled for tea in the ‘staff room', between the kitchen and the staircase that went up from the centre of the hall.

‘I'd better confirm to the cops in Aberystwyth that they've probably got an unexplained body on their patch,' said Richard. ‘They'll have to inform the coroner first of all.'

‘Could it be an accident or a natural death?' asked Moira, pouring Brooke Bond into the cups from a large brown pot.

‘Could be, I suppose. But when, that's the question? It was about three feet down and it takes a long time for that thickness of peat to accumulate if the deceased just fell on to the surface.'

‘Someone would have seen him then,' objected the ever-practical Sian. ‘Someone must have dug a hole to put him in.'

Priscilla looked doubtful. She had plenty of experience of holes in the ground from her work as an archaeologist.

‘You can't be certain about that. Bogs change all the time and there may have been a pool there at the time he was dumped, which would have put him in deeper.'

‘We're saying “he”,' said Angela. ‘It could be a woman.'

‘True enough, replied Richard, taking one of Moira's Welsh cakes. ‘But what about this bit of string, Priscilla?'

She had been cast as the expert on ancient bodies, with her qualifications as an anthropologist.

‘Some of the other bog people were found either with their throats cut or with a ligature, presumably having been strangled,' she replied. ‘But I think Richard's right, we won't know until it's dug up!

fter he had the phone call from Garth House, Meirion Thomas knew he was in for a busy time. He was a detective inspector in Aberystwyth, the only one that the rural county police force possessed. It effectively made him the head of the CID, commanding a couple of sergeants and a few detective constables.

Though covering a large area, it was sparsely populated, except in the summer, when holidaymakers flocked to the beautiful coast and mountains. Meirion's usual diet of criminal investigations consisted of housebreaking, theft of outboard motors and sheep stealing. To have a buried corpse was indeed a novelty.

As Richard Pryor had anticipated, Meirion's first task was to notify the coroner, a local solicitor in the town. This gentleman was a little hesitant about taking official notice of the matter, as he felt that so far, the evidence of a corpse buried near Borth was a little flimsy. He recalled reading about a fellow coroner in London, who some years ago had declined to hold an inquest on a decayed foot found inside a shoe. It had been washed up on the banks of the Thames, but that coroner had decided that he had no proof that the owner of the foot was necessarily dead!

Cautiously, his Aberystwyth counterpart asked the detective to keep him informed of any developments and Meirion went off to arrange for the two young botanists from the university to revisit the scene next day.

Early in the afternoon, he picked them up from Penglais, the hill overlooking the town where many of the college buildings stood, and took Louise Palmer and her student away in a black Wolseley driven by his sergeant, Gwyn Parry. A small van followed them, containing a couple of uniformed constables and some scene equipment. They drove north up the main A487 road through Bow Street, then turned left on to a minor road that looped down towards Borth. After Louise's description of where in the bog they had made their discovery, the DI parked just beyond the hamlet of Llancynfelyn and they walked across sloping fields down to the level plain of the bog. Geraint Williams soon found the spot where his ragged piece of gorse was still sticking up from the bore hole.

‘Here we are, the spot marked “X”!' he said with almost proprietorial satisfaction. ‘The ground has dried out a bit since then.'

The detective inspector stared at the mottled browns and greens of the soggy marsh without enthusiasm. He was a stocky, red-faced man of about forty-five, looking more like a farmer than a police officer. This image was enhanced by the long, belted brown raincoat and the flat cap whose peak was pulled down over his forehead. He had a hunch that they were all wasting their time and that a dead sheep lay under the coarse grass and sphagnum moss at their feet. But his immediate superior, a superintendent who was also the Deputy Chief Constable, had said that both the forensic boys in Cardiff and this new Home Office chap in Tintern had declared the stuff that these students had found was human, so they had no choice but to investigate.

His detective sergeant, though younger and thinner, was another officer of agricultural appearance. Both of them were from farming families and spent a lot of time at night crouched under hedges or in the back of plain vans, waiting in a usually futile attempt to ambush the gangs of Midlands rustlers who invaded Mid-Wales in the small hours. Not unnaturally, sheep were very familiar to them and Gwyn Parry had similar thoughts as his DI about this patch of bog probably hiding a four-legged victim.

‘What do you want to do about it, Meirion?' he asked in Welsh. The inspector pointed behind him to where two constables were approaching, carrying bundles of stakes and a coil of rope.

‘Can't start any digging until the doctor comes tomorrow,' he replied, using English for Louise's benefit. ‘We'll have to organize some muscle from the uniformed boys to do that. Just get our lads to put a cordon around this patch of ground. Though if this young lady is right and what's down there is a couple of thousand years old, I can't see that fencing it off for a night is going to matter much!'

Moira took the call from Aberystwyth later that afternoon and went to find Richard, who was up with Jimmy Jenkins on the sloping field behind the house. They were discussing the two long rows of young vines that they had recently planted, the first stage in Richard's almost obsessive desire to start a vineyard at Garth House.

He came in to speak to Meirion Thomas, who confirmed the arrangements for digging into the bog next day. Having already discussed it with Priscilla, he suggested to the detective that it would be wise to have someone else there who had experience of archaeological excavations, either an academic or the county archaeologist, if there was one. Confirming that they would be at the police headquarters by eleven o'clock, Richard went off to talk to the rest of the team.

‘Who's coming with me tomorrow?' was his first question, as he entered the laboratory. Angela pre-empted any discussion by nominating Priscilla.

‘She's the obvious person for this one, with her anthropology and museum experience,' she declared. ‘Anyway, someone has to look after the shop and I'm still settling in after being away for weeks.'

Richard suspected that she was being diplomatic in not wanting her friend to feel as if she was being sidelined, now that she herself was back in harness, but it did seem sensible to take someone who had the most appropriate knowledge.

‘An early start, then,' he said briskly. ‘If it proves to be more than a dead sheep, we may have to stay the night, so throw your toothbrush into a case. It's at least three hours' drive from here to Aber, so wagons roll soon after seven o'clock.'

Next day, the autumn dawn had grown into a red sky over the eastern rim of the valley as the black Humber Hawk set off northwards. Richard Pryor had bought it second-hand when he came home from Singapore almost a year before and, like his vines, it was his pride and joy. The car purred its way towards Monmouth and he settled back for the long ride, feeling contented at doing a job he relished, in spite of its often morbid and sometimes distasteful nature. He was glad to be back in his native Wales after fourteen years in the Far East – and glad also to be sitting alongside such an attractive and vivacious woman as Priscilla Chambers. Today she was dressed in gear suitable for digging corpses from a swamp, but still managed to look elegant. She wore a military-looking raincoat over a green roll-neck sweater and grey trousers. If necessary, her ‘sensible' shoes could be replaced by a pair of wellingtons carried in the car boot.
