Fifty yards further on and the world changed: they were free, wonderfully released from the grey gloom of the fret, and instead swamped by sunshine. The fret was only a hundred yards wide, beyond the beach the sun shone unfettered. The seascape seemed bathed in all the extra light the landscape had lost. Shaw remembered the sensational switch of colours, from sepia to blue and green, and then, half a mile ahead of them, the mustard-yellow sands of East Hills topped with its ridge of pine trees. And not a single human being in sight.
It had been his first trip to the island of East Hills. He’d been allowed to explore after they’d eaten a picnic. And running along the island’s single path, which clung to the ridge, he’d got to the northern point and made his great discovery. Nestling amongst the stone pines, almost lost in the encroaching sands, had stood the pillbox. Looking inside he’d let his eyes adapt to the dark so that he could see the remains of an old fire, a few bottles and some litter. He’d looked out through the gun slit to sea and felt the beginnings of a thousand daydreams, in which this secret place would provide the stage and the backdrop. But what he’d never imagined was that the place may have had a past of its own. That close to the pillbox the Stay Behind Army might have dug one of its secret dugouts. That it might still be there. And that it might be the answer to everything.
FORTY-ONE
Inside the sea fog the light levels were astonishingly low, as if dusk had fallen and night was gathering. And the temperature was cool, autumnal, with even a hint of ice. Valentine sat in the RNLI inshore boat with his back to the prow, watching the shadowy outline of the quayside at Wells recede behind Shaw’s shoulders. The DI had declined to explain the rationale behind their being in a boat heading for East Hills, and Valentine’s pride prevented him asking the same question twice. The Andora Star, the East Hills ferry, lay moored, all trips cancelled for the day. Beside them sat Ruth Robinson. She hadn’t said a word since they’d left The Circle. They’d found her alone, two coffee cups untouched on the table, her hand held in a fist. When Shaw had asked she’d unflexed the fingers and they’d seen what she held: a single cyanide pill.
‘He said I should take it,’ she’d said, sitting at the table, her voice dull with shock. ‘That it was for the best because he wouldn’t be coming back. He said you’d never find his body. Why was that important?’ She looked at Shaw, appearing to search his face for the answer. ‘He said that he’d done it all for me. All? I don’t dare think what he meant.’ She covered her mouth with both hands. ‘I won’t dare.’ She’d shaken her head, struggling to understand. ‘We said goodbye,’ she added, pushing the pill away. ‘I couldn’t take it.’ Shaw noticed the patina of tiny cracks in the seventy-year-old rubber casing of the pill. ‘I said I’d be here for Tilly, now Marianne’s gone, and I will be. I told Aidan that and it seemed to suck the life out of him. I’ve never seen him so. .’ She searched for the word, her eyes filling with water. ‘Crushed.’ She brushed the tears from her eyes roughly with the back of her hand. ‘I can’t understand what’s happened to us; what’s happening to me.’
Since then, silence. But she hadn’t complained, following them to the Porsche and then sitting quietly as Shaw drove down to Wells. No questions, which told Shaw he was right. Using the hands-free he arranged for the RNLI’s inshore boat to be at the quay. And he’d summoned back-up — the police launch from Lynn, but they’d be an hour. The coastal forecast he’d picked up from Petersen on duty watch at the lifeboat house. The fret was thickening and ran out for nearly a mile, nearly to East Hills, but not quite.
When he said the words ‘East Hills’ on the mobile he looked in the rear-view mirror and watched her close her eyes. At the lifeboathouse they said that ‘Tug’ Coyle’s boat had gone from its buoy in The Cut. Petersen had heard an engine chugging past about two hours ago, just seen, off the point. ‘A small fishing boat, but not Coyle at the helm,’ he said.
‘We know,’ said Shaw, seeing again the body strapped to its chair, the heels bloody. Shaw looked ahead into the mist. On the port side he could see the first of the buoys leading out of the harbour: green, the size of a small car, rusted. He steered the boat a few degrees to starboard and let the engine pick up a few revs. A pain cut across his blind eye but it bled away as soon as he closed it, and he was relieved to feel that his heartbeat remained stable.
The second green buoy came into sight just as he lost contact with the grey outline of the pinewoods on shore. Now there was nothing but the buoy itself in the circular, colourless world which surrounded the boat. He cut the engine and started using the single paddle, switching from port to starboard expertly, guiding the boat ahead. The only chance he had, thought Shaw, was to approach the island silently. Visibility was about thirty yards but it seemed to lessen unpredictably, the mist suddenly closing around them. It was like a pulse — the mist thickening, then thinning, as if the fret was breathing.
The foghorn boomed.
Valentine had rooted out a flask in her kitchen before they left and made tea — dark, steeped with tannin. He poured some into the cap and offered it to her. When she took it her hand was steady, but she didn’t raise it to her lips, she just cradled it for warmth.
The foghorn boomed again and this time it seemed to release something within her, as if a lock had been picked. She looked about her for the first time and saw nothing but the circular grey horizon. ‘He never did tell me everything,’ she said, her voice a whisper, as if she were holding a conversation in her own head. ‘But I trusted him.’ She hauled in some air. ‘The night of the East Hills killing, the day of the murder,’ she added, as if it was an accusation, ‘I couldn’t find Aidan. He wasn’t up at the house, at The Circle. His Mum said Tug Coyle had phoned from a call box, and they were going out night fishing, and that Aidan was in town getting bait. That she wasn’t to worry. I was hurt. They did go fishing, the two of them, but I was only back for the summer and it was Saturday night, so it felt like he didn’t care. It was Mum who told me about East Hills because it was on the radio. She’d had a call from Lynn to say Marianne would be dropped home after she’d given a statement; they were all giving statements, so there was nothing to worry about. So we waited. She was in bits, really, hysterical, when the police dropped her at our house. Dad gave her a drink and I got her to bed. It was late — after eleven — and there was another call. It was Tug again — he didn’t say where he was, just that I was to meet Aidan the next evening at dusk on Holkham Beach. There was no need to worry or mention the call to anyone else, Tug said, but I should bring the first aid kit from the Lido.’
She’d been staring into the mist but now she glanced back to Shaw. ‘I did a course when I got the job — the summer before Durham. So Aidan knew I could do stitches.’
Ahead Shaw caught sight of the pines on East Hills, then lost them again in the fold of the mist.
‘Tug brought him ashore — they were in his fishing boat, not the ferry. Aidan looked dreadful — dirty, like he hadn’t slept. And pale — almost bloodless. We went into the woods and he took his shirt off and there was this knife wound — a few inches, clean but deep, and there’d been lots of blood. I said I wouldn’t do anything unless he told me what had happened. He said he couldn’t tell me.’
