Fry turned to see Detective Inspector Paul Hitchens approaching the inner cordon, casually clad in jeans and green wellington boots, as if he’d only popped out to walk the dog on a Sunday afternoon.

‘Morning, sir.’

‘Morning, Diane.’ He looked down at the sea of mud. ‘That’s just great. What a start. But I suppose it makes a change from our own plods doing the trampling.’

‘Does it? I can’t see any difference from where I’m standing. All size-twelve boots look the same to me. I’m not bothered what type of helmets they were wearing when they were doing the trampling. It’s not as if they were bouncing around on their heads, is it?’

‘True.’

‘If we found an imprint of a Derbyshire Constabulary cap badge in the mud, that would be a different matter,’ said Fry. ‘Then we’d be looking for some uniformed idiot who’d tripped over his own feet. And we’d have a list of potential suspects right under our noses.’

Hitchens laughed. ‘Shall we have a look at the centre of all this attention?’

With DC Murfin trailing reluctantly behind, they followed a line of wooden planks borrowed from the builders to create a temporary bridge. Their feet thumped on the planks as if they were walking out on to a pier at the seaside. Blackpool, with mud.

And here was the end-of-the-pier show – a sort of gipsy fortune teller lurking in her shadowy tent, consulting the bones.

The Home Office pathologist, Mrs van Doon, straightened up as they approached. She brushed a stray lock of hair from her forehead, leaving a smear of dirt from her glove across her temple.

‘I shouldn’t worry too much about contamination of your crime scene,’ she said. ‘This body has been here long enough for half the population of Derbyshire to have passed through the area on their way to the pub and back again.’

Murfin looked suddenly interested. ‘There’s a pub?’

‘In the village,’ said the pathologist, gesturing with a trowel. ‘About a mile in that direction.’

Hitchens grunted impatiently. ‘How long has it been here exactly?’

‘Exactly? Is that a joke, Inspector?’

‘Make an estimate, then. We won’t hold you to it.’

‘On that understanding …’ Mrs van Doon gave an apologetic shrug. ‘A year or so? I assume you’ll be getting the forensic anthropologist in to examine the remains. Dr Jamieson might be able to give you a better estimate.’

‘At first glance, the body looks pretty well preserved to me,’ said Hitchens.

‘Oh, you’re looking at the hand. Well, the hand isn’t too badly decomposed, that’s true. But it had been well covered up and protected from the air – at least, before some individual stuck the edge of a spade through the plastic sheeting. There are some old rips in the covering at the head end, though. So the condition of that area of the body is a bit different.’
