Nothing had disturbed Marie's body during the night – not even the mountain hare that had pattered across her legs and squatted on her shoulder to scratch at patches of its fur. The hare was still brown and ragged, instead of in its winter camouflage white. It defecated on Marie's neck and left a scattering of fur, dead skin cells and dying fleas for the pathologist to find. For a long while afterwards, Marie lay waiting, just as she had waited in life.

Later in the morning, a patrolling Peak Park Ranger almost found Marie, but he stopped short of the summit when he saw more snow coming towards him in the blue-grey clouds rolling across Bleaklow Moor. He turned back to the shelter of the briefing centre in the valley, retracing his own footsteps, failing to notice the smaller tracks that ended suddenly a few yards up the hill.

When the fresh snowfall came, it quickly covered Marie's body, gently smoothing her out and softening her outline. By the end of the afternoon, she was no more than a minor bump in the miles of unending whiteness that lay on the moors above the Eden Valley.

That night, the temperature dropped to minus sixteen on the exposed snowfields. Now there was no hurry for Marie to be found. She would keep.

Detective Sergeant Diane Fry knew she was going to die buried under an avalanche one day – an avalanche of pointless paperwork. It would be a tragic accident, resulting from the collapse of a single unstable box file under the weight of witness statements piled on top of it. The landslide would carry away her desk and swivel chair and smash them against the wall of the CID room like matchsticks. It would take days for the rescue teams to locate her body. When they did, she would be crushed beyond recognition, her bones flattened in the same way that the reports on her desk were even now pressing down on her brain.

The piles of paper reminded her of something. She turned her head and looked out of the window, squinting to see past the condensation that streaked the panes. Oh yes. Snow. Outside, the stuff was piled as high and as white as the paperwork. She couldn't decide which was worse.

Then she felt the touch of warm air. It came from the noisy fan heater that she'd stolen from the scenes of crime department that morning before the SOCOs arrived for work. The paperwork was just about preferable. At least it meant she could stay in the warmth for a while. Only masochists and obsessives chose to wander the streets of Edendale on a morning like this. Ben Cooper, for example. No doubt Cooper was somewhere out there even now, conducting a one-man crusade to clean up crime, despite the icicles hanging off his ears.

Soon, scenes of crime officers would be scouring the building for their missing heater. Eventually, she would have to give it up, unless she could find somewhere to hide it when she heard them coming. You could always tell when the SOCOs were coming by the sound of their grumbling. But the heater was the only source of warmth in the room. Fry put a hand to the radiator on the wall. It was warm, but only faintly. It felt like a body that hadn't quite cooled but had already gone into rigor mortis. No need to call in the pathologist for a verdict on that one. Dead for two hours, at least.
