Logan hoped to God she was right.

By the time the Deputy Procurator Fiscal arrived, the search was underway. The fog-smothered car park was stuffed to the gunnels with patrol cars and police transports, all of them in need of a good wash. She pulled up at the far end, blocking in a small sports car. This was it: the big one. Two dead women in just over a week, both stripped and badly beaten; it was either a serial killer or one hell of a coincidence.

Smiling grimly, she headed up the hill, following the intermittent lightshow of police torches through the thick mist.

A serial killer for her very first case. OK, technically it was the PF's case, but she was assisting, holding the fort until the Fiscal got here. And Rachael Tulloch couldn't have hoped for a better chance to shine. The investigation would draw a lot of publicity, and publicity meant promotion. Provided no one screwed up and let the bastard get away, that was.

She stomped past a cordon of uniformed constables, all done up in bright yellow reflective vests, poking and prodding their way methodically through the undergrowth. It all looked extremely efficient. Probably that Detective Inspector Insch.

Everyone in the Aberdeen office had a lot of respect for the man, not like some of the DIs she could mention.

There was no sign of Insch when she got to the top of the hill, but most of the activity in the clearing was centred on a shortish figure in an SOC boiler suit with a fag hanging out of the corner of her mouth. Rachael's heart sank. If this was still DI Steel's case there was no chance it was ever going to be a success. She'd not done a lot of work with the inspector – just the Rosie Williams case, and that dog's torso in the woods – but so far she wasn't impressed. And she'd heard all about how the inspector had screwed up the Gerald Cleaver trial just last year – a known paedophile with a track record of violent abuse going back years, nearly twenty victims prepared to testify, and Steel still couldn't get a conviction.

They were doomed… But that didn't mean Rachael Tulloch wasn't going to do her job properly.

Straightening her shoulders, she struggled into a white paper boiler suit, marched up to DI Steel and demanded an update. And shouldn't she put that cigarette out? This was a crime scene after all! The inspector raised an eyebrow and stared at her, leaving a gap that was far longer than strictly necessary before asking if there was something rammed up Rachael's arse. Because if not, the inspector's size six Wellington boots could be. Rachael was too stunned to speak.

'Listen up, Curly-top,' said Steel, flicking a small flurry of ash from the end of her cigarette, her voice cool and level.

'I am having a fag because we have already searched every square inch of this clearing. I am a detective inspector with Grampian Police, not some fucking numptie for you to order about. Understand?' DI Steel turned and dismissed the clump of constables surrounding her with an amiable, 'You lot bugger off back to your jobs. I want this whole forest turned upside down. And I mean the whole forest! No skipping bits.

Rabbit holes, streams, bushes, nettles, badgers' bum holes: everything gets searched.' They yes-ma'amed their way off into the fog, leaving DI Steel and a blushing deputy procurator fiscal alone in the middle of the clearing, surrounded by sculptures that reeked of death.

'You want to start over again?' asked the inspector.

Logan walked on his own through the fog, following the squelchy path, checking up on the search teams. The whole thing was pretty much a waste of time, crawling about in the damp grass looking for clues that weren't there. Other than the victim's handbag – currently undergoing every test the IB could think of – the immediate scene had turned up empty. It didn't help that the only place they might have found something concrete, the car park, was now covered in SOC vehicles, minibuses and patrol cars. Any trace evidence ground into the mud and gravel by countless police tyres and size nine boots. The search teams might get lucky and find something else the killer had missed, but Logan doubted it: pick up the girl, park the car, force her out into the rain, beat her to death and strip her corpse. The end. Whoever it was, he didn't go traipsing about the forest in the middle of the night, scat ering clues about like some demented evidence fairy.

Logan picked his way across a slippery bridge and headed uphill. The last search team was on the south side of the forest, working their way back towards where the body was discovered. Pointless it might be, but DI Steel wanted this one done by the book. Maybe there was hope for her yet?

The team was working its way down a steep slope when he found them, prodding the undergrowth with sticks and poles, going through the motions. A familiar face scowled at him as he struggled up the track – that grumpy cow from last Monday night, the one who'd had a go at him for PC Maitland getting shot. And working next to her was someone he hadn't expected to see: WPC Jackie Watson prodding about in a holly bush, using her plaster cast to hold back a spiny-leaf-covered branch as she jabbed away with a pole.

She didn't look too happy either. He pulled her to one side.

'What the hell are you doing out here?'

'Relax,' she smiled. 'I'm not really here. Right now I'm collating the division crime statistics for the year to date: says so on the roster, so it must be true.'

'Jackie, you can't do this! You're supposed to be on light duties, not operational! If the inspector finds out you'll be for it!'

'Steel? She couldn't give a toss. Look, I just wanted to be out of the office for a bit, OK? Do some real bloody police work for a change, instead of shuffling bits of paper about.'

Jackie threw a glance over her shoulder; a goldfish-faced sergeant was coming their way, all fake suntan, puffing cheeks and ping-pong eyes. 'Now bugger off, before you get us into trouble.'

'Is there a problem?' asked the sergeant. Logan took one last look in WPC Watson's direction and said that no, there wasn't, how was the search going? Sergeant Fish-Face wrinkled his nose. 'We're miles away from the crime scene and there's no way in hell anyone would cart a body all the way through this, when he could just drag it a fraction of the distance up from the car park. It's a complete waste of everyone's time.'

Logan made soothing noises, it was important to be thorough, everyone appreciated his team's efforts, blah, blah, blah… The grumpy WPC had been hanging back as Logan and Sergeant Goldfish talked, ignoring the line as it moved slowly away into the mist. 'What the hell are we doing out here?' she demanded, her face like a skelped arse.

Logan only had time to open his mouth before the sergeant roared, 'You're here because you're supposed to be a bloody police officer. Now get your backside back to work before I kick it from here to Peterhead!'

She scowled at Logan like it was his fault she'd been yelled at, then turned on her heel and started stabbing the nearest bush with all the venom she could muster, muttering obscenities under her breath as she caught up with the rest of the search team, rejoining the line next to WPC Jackie Watson. Thirty seconds later Jackie cast a glower back in his direction and Logan sighed. The bloody woman was probably telling Jackie what an utter shit he was. And from the expression on Jackie's face it looked as if she agreed. So much for getting back on an even keel. Their curry-fuelled truce had lasted a whole day.

Enough was enough: Logan was going to- A sudden scream pierced the fog, before being quickly swallowed by the trees and mist. There was silence for a heartbeat and then everyone exploded into action. Logan scrambled down the hill, towards the search team, Sergeant Goldfish hot on his heels, making for the source of the scream. They slithered to a halt at the top of a nearly vertical slope punctuated with deep beds of stinging nettle and spiky gorse.
