Dead Man's Footsteps

system and then flushed out of the sewage outfall into the sea – thinking a sufficient distance from the shore for sewage would be a safe enough distance for a body.’
    Grace stared again at the skeleton, unable to get the possibility that it was Sandy out of his mind.
    ‘Perhaps her killer hadn’t considered the drain not flooding,’ Theobald went on. ‘He hadn’t reckoned on her getting embedded in the silt, and because the water table was down, there wasn’t enough flow through the drain system to wash her free. Or maybe the drain went out of use.’
    Grace nodded, looking again at the twitching thread.
    ‘It’s a carpet fibre, that’s what I think. I could be wrong, but I think the lab analysis will show it’s a carpet fibre. Too hard to be from a pullover or a skirt or a cushion cover. It’s a carpet fibre.’
    Joan Major nodded in agreement.
    ‘Where did you find it?’ Grace asked.
    The forensic pathologist pointed at the skeleton’s right hand, which was partially buried in the silt. The fingers were exposed. He pointed at the end of the middle finger. ‘See that? It’s an artificial nail – from one of those nail studio places.’
    Grace felt a chill run through him. Sandy had bitten her nails. When they were watching television she would chew on them, making busy little clicking sounds like a hamster. It drove him nuts. And sometimes in bed as well. Often when he was trying to go to sleep, she would be gnawing away, as if fretting about something she could not or would not share with him. Then suddenly she’d look at her nails and get angry with herself, say to him that he must tell her when she was biting and help her to stop. And she would go to a nail studio to have expensive, artificial nails put over her bitten ones.
    ‘A plastic compound, glued on, somehow the nails didn’t get washed away when the skin beneath rotted,’ Frazer Theobald said. ‘The fibre was beneath this one. It could be that her assailant dragged her along a carpet andshe dug her nails in. That’s the most likely explanation of how it got there. Bit of luck that it didn’t get washed away.’
    ‘Luck, yes,’ Grace said distantly. His mind was racing. Dragged along a carpet. A blue carpet fibre. Pale blue. Sky blue.
    There was a pale blue carpet at home. In the bedroom. The bedroom he and Sandy had shared until the night she disappeared.
    Into the blue.

11 SEPTEMBER 2001
    Ronnie had been running for maybe a minute when day changed into night, as if there had been an instant, total eclipse of the sun. Suddenly he was stumbling through a choking, stinking void, with the sound of thunder in his ears, thunder that was rising from the ground.
    It was as if someone had emptied a billion tons of foul-smelling, bitter-tasting black and grey flour into the sky directly above him. It stung his eyes, filled his mouth. He swallowed some of it and coughed it back up, immediately swallowing more. Grey shapes like ghosts swirled past him. He stubbed his toe painfully on something – a fire hydrant, he realized – as he tripped over the damned thing and fell forward, hard, on to the ground. Ground that was moving. It was vibrating, quaking, as if some giant monster had awakened and was breaking free from the belly of the earth itself.
    Have to get out of here. Away from here .
    Someone trod on his leg and crashed down on top of him. He heard a woman’s voice, cursing and apologizing, and smelled a fleeting whiff of fine perfume. He wriggled free of her, tried to stand up, and immediately someone slammed into his back, hurtling him forward again.
    Hyperventilating in panic, he scrambled to his feet and saw the woman, looking like a grey snowman clutching apair of court shoes, get up. Then a huge fat man with mad hair crashed into him, cursing, punching him out of the way, and ran stumbling on to be swallowed by the fog.
    Then he was knocked over again. Got to get up. Get up. Get up!
    Memories of reading about people being crushed to death in panicking crowds swirled in his mind. He struggled to his feet again, turned, saw more snowy figures lumbering out of the gloom. One knocked him sideways. He searched through the oncoming legs, shoes, bare feet, for his bag and his briefcase, saw them, ducked down, grabbed them both, then was barged over on to his back again.
    ‘Fuck you!’ he screamed.
    A stiletto heel passed over his head like a spiky shadow.
    Then suddenly there was silence.
    The rumbling stopped. The
