from the marsh itself. Ruth gets out her torch but its shaky light shows her only flat marshland in all directions. Far off, she can hear the sea roaring as it thunders inland. She tries to get out her map but it is blown back in her face. It is too precious to lose so she packs it away again. She can hear the sea but from which direction? She gets out her compass. She is heading too far to the east. Slowly, trying not to panic, she revolves on the spot until she is facing south, then sets out again.
This time she stops because her foot steps into nothingness.
Literally one minute she is on dry land and the next she has sunk knee-high into the bog. She almost falls on her face but manages to save herself, rocking backwards until she is sitting on the firm ground. With an effort she pulls her leg from the liquid mud. It comes free with a horrible squelching sound but her wader, thank God, stays on. Panting, she takes a step backwards. Firm Ground.
Step forwards. Oozing mud. To the right, more mud. To the left, firmer ground. She starts to edge to the left, her torch held out in front of her.
After a few yards, she falls headlong into a ditch. Putting out her hands to save herself, she encounters icy water. She raises a hand to her lips. Salt. Oh God, she must have wandered right out to the tidal marsh. Scrambling to her feet she wipes mud off her face and checks her compass again. Due east. Has she missed the path altogether? Is she heading straight out to sea? The roaring in her ears is so loud now that she cannot tell if it is the sea or just the wind. Then a wave breaks right over her feet. There is no mistaking it, a freezing, briny-smelling swell of water. She is on the tidal mudflats, possibly at the very spot where Peter called for help all those years ago. But there is no Erik to save her. She will be drowned right here on the desolate marshland with a priceless Iron Age torque in her pocket.
She is sobbing now, her tears mingling with the rain and sea water on her face. Then she hears something so miraculous that she almost discounts it as a mirage. A voice. Calling her. She sees a light, a shaky hand-held light coming towards her. ‘Help!’ she shouts frantically, ‘Help!’
The light comes nearer and a man’s voice shouts. ‘Come this way. Towards me.’ Almost on all fours, she crawls towards the light and the voice. A figure looms out of the mist, a thick-set figure wearing a reflective jacket. A hand reaches out and grabs hers. ‘This way,’ says the voice, ‘this way.’
Clinging on to the yellow waterproof sleeve as if it were a lifebelt, she stumbles along beside the man. He seems familiar somehow but she can’t think about that now. All she can do is follow him as he traces a circuitous path, first left and then right, now into the wind, now away from the wind, through the mudflats. But whatever route he is taking seems a remarkably effective one. Her feet are on firm ground almost all the time, and before too long she can see the blue and white police tape and the car park where a battered Land Rover is waiting.
‘Oh my God.’ She lets go of the man and leans over to catch her breath.
The man steps back, shining his torch into her face.
‘What the hell were you playing at?’ he demands.
“I was trying to get home. I got lost. Thank you. I don’t know what I would have done if you hadn’t come along.’
‘You’d have drowned, that’s what you would have done.’ Then his voice changes. ‘You’re the girl from the university, aren’t you?’
Ruth looks at him, taking in close-cropped grey hair, blue eyes, official-looking jacket. It is her neighbour, the warden of the bird sanctuary. She smiles. Despite her feminist principles, she quite likes being called a girl.
‘Yes. You’re my neighbour, aren’t you?’
He holds out a hand. ‘David.’
She shakes hands, smiling again at the strangeness of it.
A few moments ago she was clinging on to his sleeve,
