‘We do this so that we can get back far enough to see the wood for the trees and get a good shot of the soil profile.’ He tapped the button again and the next shot came up: a flat-on picture of the grave profile. Shaw could see the various layers of the soil — the black decaying humus at the top, a dark layer of soil, a thin yellow line where the clay began and then the grey, almost silvery, waterlogged strata below.
Valentine yawned so wide that a bone in his jaw cracked.
Hadden looked at the DS’s exposed teeth. ‘A soil profile can tell you as much as a fingerprint. It’s evidence, very compelling evidence, if you read it properly, and interpret what it’s telling us.’
Valentine looked at the screen.
‘Now,’ said Hadden, his eyelids closing, then fluttering slightly as he concentrated. ‘You need to recognize that you’ve had a big slice of luck here, because the archaeologists who found our victim’s bones dug out the grave using a mechanical digger, so it’s really precise — engineered, if you like. What this picture shows, I believe, is that
Shaw stood, staring into the bright image. Hadden was right, because the neat wedding-cake layers had been disrupted, the shadow of the hole breaking the thin yellow clay line.
Which left them with one key question. ‘When?’ asked Shaw.
‘Well, I know someone at Cambridge’s soil-science lab who can give us a better call, but I’d guess — and it’s a good guess — that we’re talking between six and eight months.’
‘This year?’ said Shaw, his voice sharp and energized. Suddenly he felt ten years younger. ‘We’re saying someone dug down towards those bones this year — then filled it in, then along came the digger?’
‘The disturbed soil,’ said Hadden, pointing at what he’d called the ‘ghost’ of the hole revealed in the soil profile, ‘has been settling for one winter, and almost certainly only one. That’s when a lot of the soil processes work through the strata — forming layers, rotting the leaves to form the mulch at the top, creating the soil.’
He interlaced his hands, turning them upside down to form a basket, to show that science could do miracles too. ‘This part of the profile, where’s there’s been disruption, is just a jumble of soil — there’s hardly any stratification.’
Valentine tried to concentrate, distracted by the gurgle of a coffee machine on the next desk. ‘We’re saying someone dug down into this grave sometime this year and then gave up?’
‘Yes. That’s right. Or they found what they were looking for and stopped,’ said Hadden. ‘Four feet brings you pretty close to the bones we found. They could have got close, then just dug at a precise spot — further down. We’ll never know because the archaeologists just ejected the spoil, as you would expect. They weren’t interested in the graves, just what was supposed to be at the bottom of them.’
‘Animals? Natural subsidence?’ asked Shaw, aware that the basis of his inquiry had just been shifted twenty-eight years closer. He felt his bloodstream coursing, as if he’d just finished his morning mile.
Hadden held up a hand, closed his eyes, thinking through Shaw’s multiple question. ‘No. Animal damage would be much more localized. Subsidence is out — you can see the underlying clay base is solid.’
Shaw tried to imagine the scene. At night, perhaps? One or more men, working by a small light, digging down towards the three buried bodies.
He clicked his fingers. Valentine winced. ‘Hold on. What about the archaeologists? Perhaps they did it, filled it in, then came back, like a trial dig to see what the soil conditions were like.’
Hadden shook his head. ‘’Fraid not, Peter. Nice try. I’ve checked.’
Shaw was still thinking. ‘George — when did the council announce the programme of reinterment? Can you find out for me …’ He held Valentine’s eyes, so that he saw the DS’s eyebrows rising slightly at the insistent tone. Valentine stood, walked towards the partition with the mortuary and flicked open his mobile.
‘They were after something,’ said Shaw, tapping the whiteboard. ‘And if they gave up at four feet, and what they wanted was at six feet, then what they wanted was still in the grave when we opened it. Or — they got close, knew exactly what they were after, and just dug down to get it — like a miniature well. To do that they’d need to know precisely its location — but then that’s not difficult if you know a few basics: like which end of the grave the head lies, that kind of thing?’
Hadden nodded and took Shaw to one of the lab tables which had been cleared and covered with a white plastic sheet. On it were the items they’d extracted from Nora Tilden’s coffin and from amongst the bones found on the coffin lid.
Each one had been labelled, numbered, dated. The green glasses with the engraved whaling scene first, the penknife, the wallet, the few coins. And from between the coffin lid and the bones, the billhook. And finally, from inside Nora’s coffin, the silver brooch.
‘No wedding ring on Nora’s hand?’ asked Shaw.
Hadden shook his head. ‘Then we go inside the wallet,’ he said. He’d set the contents out separately, under a single sheet of glass: the rotted pieces of paper, one with the faint pen strokes of the gibbet and hanging man just visible. There was one rectangular piece of paper, white, as if it had been leached of colour. ‘I’m working on that — maybe a receipt?’ said Hadden. ‘The paper’s shiny, like …I don’t know — a football match ticket? A concert? I can’t raise any images at the moment but it’s early days. Just a three-letter grouping — MOT, just that — with a space before and a space after. That’s all I can get — MOT. It could be an MOT certificate, I suppose — I’ve asked someone to track down a copy of the standard form from 1982, see if it matches.’ He let Shaw think about that, rearranging the remains of a ten-pound note and three fives.
‘Big question is — if they were after one of these items, which one was it?’ asked Hadden, smiling broadly, enjoying himself.
‘The penknife,’ said Shaw. ‘George says it’s a collector’s item — and a link to the GIs. So maybe that?’
‘Maybe.’
‘The billhook?’
Hadden picked up the bagged item and turned it so that Shaw could read the word stamped into the metal haft, where it sank into the wooden handle.
STANLEY
‘Toolmaker’s name,’ said Hadden. ‘No other marks.’
Valentine came back, his mobile extended with a straight arm. There was a text on screen from Paul Twine: 18 JUNE 2010.
‘Bang on six months,’ said Valentine.
‘So, last June the council announces the coffins are coming up, someone panics, thinks we’ll find the bones and some evidence which points to the identity of the killer. They go to the cemetery after dark, dig down. Someone, clearly, with a lot to lose,’ said Shaw, turning to Hadden.
Hadden nodded. ‘Maybe. I just do the science, Peter. The clever stuff’s all yours.’
‘There was something else in the grave,’ said Valentine. ‘Garrison’s bones. Perhaps they wanted to get him out. Then there’d be no inquiry at all. Fuck all. But they gave up.’
Dr Kazimierz pushed her way through the swing doors and helped herself to coffee. She caught Shaw’s eye, smiled, then retreated back through the doors. The greeting had been warmer than usual, and Shaw wondered if the meeting with Dawid on the beach had been a rite of passage, an entry into a different circle of friendship.
‘George,’ said Shaw. ‘After we’re done, ring Paul. I want everyone to know that we need to focus on this attempt to reopen the grave. The timeline is pretty conclusive. Night time? Almost certainly. How’d they do that? Let’s crawl all over this — local uniformed squad cars, beat, council security, any local low life that hangs out in the cemetery after dark — you know the score, brief everyone. This may well be a cold case, George — but it just got a whole lot hotter. And tell Jacky to rerun the door-to-door in the immediate vicinity — someone must have seen or heard something.’
Shaw took a deep breath. Beside the swing doors there was a tray of boiled sweets. He took one, passed another to Valentine.
‘Ready?’ he asked, with the surfer’s smile. ‘Or are you going to fit in a quick bacon sandwich?’
Valentine didn’t smile back. ‘On the subject of food …’ He took out his wallet and slipped out a ticket, handing it to Shaw. It was for the Shipwrights’ Hall Christmas dinner they’d seen advertised on Freddie Fletcher’s wall at the PEN office.
