'I didn't kill no one!'

'Stop fucking about, Jamie – I'm not in the mood.'

He slumped back in his seat, chewing things over. 'I really don't get a lawyer?'

'No! Now tell us about Rosie Bloody Williams before I pull that stupid-looking chin-warmer off your face, one hair at a time!'

Jamie held up his hands in self-defence. 'OK, OK! We're … you know… I stayed with her for a bit…'

'You were her pimp.'

'We're having fun, you know…'

'Fun? Rosie was old enough to be your granny! She's out there shaggin' for cash, every night, while you're what?

Staying home looking after the kids?'

Jamie stared down at his hands. 'Isn't that old.'

'Yes she fucking was! Ugly as hell too!'

'She is not!' Jamie's voice was getting louder with every word. 'She isn't ugly!'

A sly smile blossomed on Steel's face. 'You loved her didn't you?'

Jamie blushed and looked away.

'You did, didn't you? You loved her and she was out there every night, some stranger's dick in her mouth. Screwing them in doorways. Your precious Rosie, out there with-'

'Shut up! Fuckin' shut up!'

'That's why you killed her, isn't it? You were jealous she wasn't all yours. Anyone could have her for the price of a burger.'

'Shut up…'

Steel settled back in her chair, scratching vaguely at the damp patch under her left arm. She nodded in Logan's direction and he asked Jamie where he was between eleven o'clock Monday night and two o'clock Tuesday morning.

'I was at home. Asleep.' But there was something in his eyes. 'Suzie'll tell you. She was there.'

DI Steel raised an eyebrow. 'No' in the same bed, I hope.'

Jamie just scowled at her. 'We've got Forensics turning your flat upside down: they're going to find her blood, aren't they? You beat her so bad, you must've been clarted in it.'

She leaned forwards in her seat, tapping the table with a nicotine-stained finger. 'Wouldn't be the first time you beat her up either, would it? She kicked you out 'cos of it.'

'I didn't mean to hurt her!' The tears were starting.

Steel's smile turned into one of triumph. 'But you did, didn't you? You didn't mean to, but you hurt her really bad.

Was it an accident? Come on, Jamie, you'll feel better if you tell us.'

An hour later they still hadn't managed to get anything else out of him. And as Steel said, it was too hot in the interview room to bugger about any longer. So down to the cells went Jamie McKinnon and down to the canteen went Logan and DI Steel. Chilled tins of Irn-Bru all round. 'Christ, that's better she said, standing outside on the rear podium two minutes later, surrounded by the patrol a'nd pool cars, drink in one hand, cigarette smouldering away in the other. 'We'll get the PF in to look at the tape. "I never meant to hurt her," my arse, all we need is a couple of witnesses and we're laughing.'

She smiled and knocked back a mouthful of Irn-Bru. 'Knew it was about time my luck changed.'

Unfortunately Logan's hadn't. When DI Steel said, 'All we need is a couple of witnesses,' what she actually meant was that Logan had to change shifts and spend the next couple of nights wandering around the docks chatting up prostitutes.

The first time in ages that his shift pattern was the same as Jackie's, and the inspector wanted it all changed again. Jackie was going to kill him.

'You're young,' Steel told him when he complained, 'you'll get over it. Better bugger off home after lunch. Get some kip. In the meantime, let's get the PF down here…'

The Procurator Fiscal and her new deputy sat through the recording of Jamie McKinnon's interview in silence. The tape was a good start, but it wasn't enough to secure a conviction, for that they'd need some real, hard forensic evidence.

'Speaking of which,' said Rachael Tulloch, deputy PF to the stars, 'how did you get on with those contraceptives?'

The Fiscal looked momentarily flustered as Logan explained about the two hundred and thirteen second-hand prophylactics sitting in the morgue's specimen freezers; it looked like this was the first she'd heard of her deputy's spectacular plan. At least Rachael had the decency to blush and admit it was a lot more condoms than she'd been anticipating, but now that they had a suspect under arrest, couldn't they match his DNA to them? Prove he was there? The Fiscal went quiet for a minute, considering it, and then agreed it probably couldn't hurt. Logan tried not to groan. Isobel was bound to blame him for all the work she was about to get. He consoled himself with the thought that she didn't like him much anyway.

When he went down to the morgue to break the bad news, Isobel was hunched over her brain-in-a-bucket again. Her reaction to Logan's request for DNA testing was pretty much what he'd been expecting. Only with more swearing.

'Don't look at me,' he said when she paused for breath.

'I told you: it's that new PR She's mad for used condoms.

Could you not just blood test the semen and only DNA match the ones with the same blood group as Jamie McKinnon?'

Reluctantly Isobel agreed that it would be a lot less work.

But she still wasn't happy. Grumbling, she dug the condoms out of the freezer, where they'd had just enough time to go hard. For the second time in their lives.

Logan checked his watch and left her to it. If he hurried he could grab lunch with Jackie in the canteen before heading back to the flat to try and get some sleep. Not that he held out much hope: he always had trouble adjusting to the night shift, and usually he had a couple of days off in between to get used to the idea. Sod the diet. He was having chips with his lasagne today. And a pudding.

Though on second thoughts, tapioca probably wasn't the wisest of choices. Looking at it, congealing in the bowl, all white with translucent lumps, all he could think of was Isobel slowly defrosting her condoms down in the morgue.

Shuddering he pushed the bowl away.

'Interfering old bitch.' Jackie stabbed her jam sponge with an angry spoon. 'Why did she have to go buggering about with your shifts? If you have to go onto nights today and tomorrow…' She did the arithmetic on her fingers. 'That puts you six days ahead of my bloody shift pattern! It took bloody ages to get the damn things in line!'

'I know, I know. I'll just have to get mine shifted again.

Though Christ knows when.'

'And I had plans.'

Logan looked up. 'Oh? We going away somewhere?'

'Not any more we're not, you'll be asleep all bloody Friday.'

Stab, stab, stab. 'Tell you I could kill her!'

'Oh-ho, speak of the devil…' DI Steel was standing in the doorway to the canteen, craning her neck. Looking for someone. And Logan had a nasty idea who. He was just about to duck down under the table, pretend he'd dropped his fork or something, when she spotted him.

'Oi! Lazarus,' she shouted and Logan winced. Every eye in the place turned to stare. 'You finished?' She didn't wait for him to answer. 'Well, come on then: we've got a shout to go to.'

Jackie leaned over the table and hissed at him, 'I thought you were supposed to be going home to get some sleep!'

It was a Mrs Margaret Hendry who'd found it, out walking her dog, Jack, in Garlogie Woods. Well, technically it had been Jack who'd found it, leaping away into the undergrowth, barking and yipping. Not coming back, no matter how much Margaret shouted. In the end she'd ducked in under the trees after him. It was just off a small clearing, wedged into the roots of a fallen tree: a red suitcase, big enough to take a week's worth of clothes. The smell was appalling: stinking, rotten meat. Jack of course had gone straight to it, and was hanging off the handle, all four little legs off the ground as he tried to scrabble inside. Well, what with the smell and the suitcase, it wasn't difficult to put two and two together. Margaret pulled out her mobile phone and called the police.
