Logan smiled like a shark. 'All in good time, sir. WPC Watson, would you be so kind as to read this gentleman his rights?'

'You're arresting me? What for? I haven't done anything!'

'No need to shout, sir. Constable, if you please...'

'Norman Chalmers,' she said, 'I am detaining you on suspicion of the murder of an unidentified four-year-old girl.'

'What?' He struggled against the handcuffs as Watson went through the remainder of the speech, shouting over and over again that he hadn't done anything. He hadn't killed anyone. This was all a mistake.

Logan let him run out of steam before holding up a set of duly signed and notarized papers. 'I have here a warrant to search these premises. You were careless, Norman. We found her body.'

'I didn't do anything!'

'You should have used a fresh bin-bag, Norman. You killed her, and just threw her out with all your other rubbish. But you didn't check for incriminating evidence, did you?' He held up the clear plastic wallet with the supermarket till receipt in it. 'Avocadoes, cabernet sauvignon, creme fraiche and a dozen free-range eggs. Do you have a Tesco Clubcard, sir?'

'This is insane! I didn't kill anyone!'

WPC Watson looked down to see a bulge in Chalmers's back pocket. It was a wallet. And there, nestling between a Visa card and membership of the local video shop was a Clubcard. The number on the card matched the one on the receipt.

'Get your coat, Mr Chalmers, you're going for a little ride.'

Interview room three was oppressively hot. The radiator pumped heat into the little beige s.p.a.ce and Logan couldn't get it to stop. It wasn't even as if they could open a window. So instead they suffered the heat and the stale air.

Present: DS Logan McRae, WPC Watson, Norman Chalmers and DI Insch.

The inspector hadn't said a word since entering the room, just stood at the back, leaning against the wall, working his way through a family-sized bag of liquorice allsorts. Sweating.

Mr Chalmers had decided not to help the police with their enquiries. 'I told you I'm not saying a b.l.o.o.d.y thing till you get my lawyer in here.'

Logan sighed. They'd been over this time and time again. 'You're not getting a lawyer until we've finished the interview, Norman.'

'I want a b.l.o.o.d.y lawyer now!'

Gritting his teeth, Logan closed his eyes and counted to ten. 'Norman,' he said at last, tapping the investigation file against the tabletop. 'We've got Forensics going through your house right now. They're going to find traces of the girl. You know that. If you talk to us now it'll look a d.a.m.n sight better for you when you get to court.'

Norman Chalmers just stared straight ahead.

'Look, Norman, help us to help you! A wee girl is dead-'

'Are you deaf? I want my f.u.c.king lawyer!' He folded his arms and sat back in his chair. 'I know my rights.'

'Your rights?'

'I have a legal right to legal council. You can't interview me without a lawyer present!' A self-righteous smile spread over Chalmers's face.

DI Insch snorted, but Logan almost laughed. 'No you don't! This is Scotland. You get to see your lawyer after we've finished with you. Not before.'

'I want my lawyer!'

'Oh for G.o.d's sake!' Logan hurled the file down on the tabletop, causing the contents to spill out onto the Formica. A photo of a little dead body wrapped up in parcel tape. Norman Chalmers didn't even look at it.

At last DI Insch spoke, his voice a low ba.s.s rumble in the crowded room.

'Get him his lawyer.'

'Sir?' Logan sounded as surprised as he looked.

'You heard me. Get him his lawyer.'

Forty-five minutes later they were still waiting.

DI Insch stuffed another multicoloured square in his mouth and chewed noisily. 'He's doing this on purpose. The slimy little git's doing it just to p.i.s.s us off.'

The door opened, just in time to catch the inspector's complaint.

'I beg your pardon?' said a voice from the door, with obvious disapproval.

Norman Chalmers's legal representative had arrived.

Logan took one look at the lawyer and suppressed a groan. He was a tall, thin man wearing a luxurious overcoat, expensive black suit, white shirt, blue silk tie and an earnest expression. His hair had more grey in it than the last time Logan had seen it, but the man's smile was every bit as annoying as he remembered. When the lawyer had cross-examined him, trying to make out that he'd fabricated the whole case. That Angus Robertson, AKA the 'Mastrick Monster', was the real victim.

'Don't worry, Mr Moir-Farquharson.' Insch p.r.o.nounced it as it was spelt 'Far-Quar-Son' rather than the traditional 'Facherson', because he knew it annoyed him. 'I was speaking about some other slimy git. How nice of you to join us.'

The lawyer sighed and draped his overcoat over the back of the last spare seat at the interview table. 'Please tell me we don't have to go through all this again, Inspector,' he said, pulling a slender, silver laptop from his briefcase. The soft purr of it powering up was almost inaudible in the crowded little room.

'All what, Mr Far-Quar-Son?'

The lawyer scowled at him. 'You know very well what. I am here to represent my client, not listen to your insults. I don't want to have to make yet another complaint to the Chief Constable about your behaviour.'

Insch's features darkened, but he didn't say anything.

'Now,' said the lawyer, picking away at the laptop's keyboard, 'I have a copy of the charges against my client. I would like to confer with him in private before we make a formal statement.'

'Aye?' Insch left his perch against the wall and leaned his huge fists against the tabletop, looming over Chalmers. 'Well, we'd like to ask your "client" why he murdered a four-year-old girl and threw her body out with the garbage!'

Chalmers jumped out of his seat.

'I didn't! Will you b.a.s.t.a.r.ds b.l.o.o.d.y listen? I didn't do anything!'

Sandy Moir-Farquharson laid a hand on Chalmers's arm. 'It's all right. You don't have to say anything. Just sit back down and let me do the talking, OK?'

Chalmers looked down at his lawyer, nodded, and slowly sank back into his seat.

Insch hadn't moved.

'So, Inspector,' said Moir-Farquharson, 'as I said: I'd like to speak to my client in private. After that we will help you with your enquiries.'

'That's no' how this works.' Insch scowled at the lawyer. 'You have no legal right of access to this wee s.h.i.te whatsoever. You are here as a courtesy only.' He leaned in so close there was barely a breath between them. 'I'm running this show, not you.'

Moir-Farquharson smiled calmly up at him. 'Inspector,' he said in his most reasonable voice, 'I am well aware of the vagaries of Scottish law. However, as a sign of good faith, I'm asking you to let me speak to my client in private.'

'And if I don't?'

'Then we sit here till the cows come home. Or your six hours' holding time run out. It's up to you.'

Insch glowered, stuffed the liquorice allsorts back in his pocket and left the room, trailing Logan and WPC Watson behind him. Out in the corridor it was a lot cooler, but the air contained a lot of swearing.

When he had finished cursing the lawyer to the four winds, Insch told Watson to keep an eye on the door. He didn't want either of them doing a runner.

She didn't look too impressed. It wasn't a glamorous task, but that's what you got when you were a lowly WPC. One day she'd make CID, then she'd be the one telling uniforms to guard doorways.

'And, Constable,' Insch leaned in closer, his voice becoming a conspiratorial whisper. 'that was a d.a.m.n fine bit of police work today: the supermarket receipt. I'll be putting in a good word for you on that one.'

She grinned. 'Thank you, sir.'

Logan and the inspector left her to it, working their way back to the incident room.

'Why did it have to be him?' asked Insch, parking himself on the edge of a desk. 'I'm supposed to be at the dress rehearsal in twenty minutes!' He sighed: there was no chance he'd make it now. 'We're going to get b.u.g.g.e.r all out of Chalmers now. G.o.d save us from crusading lawyers!'

Sandy Moir-Farquharson was notorious. There wasn't a single criminal defence lawyer in the whole city who could hold a candle to him. Aberdeen's best solicitor advocate, qualified to stand up and defend the guilty in open court. For years the Crown Prosecution Service had been trying to get him to come over to their side, act as a public prosecutor, help put people away, instead of getting them off. But the slippery wee sod wasn't having any of it. He was on a mission to prevent miscarriages of justice! To protect the innocent! And get his face on the telly at every available opportunity. The man was a menace.

But secretly Logan knew if he ever got into trouble himself, he'd want Slippery Sandy representing him.

'So how come you let Hissing Sid suspend the interview?'

Insch shrugged. 'Because we were never going to get anything out of Chalmers anyway. At least whatever the Snake comes up with will be entertaining.'

'I thought he was busy representing our favourite child molester, Gerald Cleaver.'

Insch shrugged and dug the bag of sweets out of his pocket. 'You know Hissing Sid. That case's got about a week, week and a half left to run. After that he's going to need something else to get his face in front of the cameras.' The inspector offered the open bag to Logan who helped himself to a coconut wheel with a liquorice centre.

'Forensics are going to find something,' Logan said, chewing. 'The girl had to be in his flat. There were food sc.r.a.ps and empty wine bottles in that bag. There's no way he could have got her into that bin-bag anywhere else... Unless he's got another property he eats and drinks at.'

Insch grunted, rummaging in the bag. 'Get onto the council in the morning. See if he's got a second property registered anywhere. Just in case.' He found what he was looking for: one of the aniseed disks with blue bobbles on it. 'Listen,' he said, popping the sweet into his mouth, 'the post mortem's been scheduled for quarter to eight this evening.' He paused, his eyes fixed on the floor at his feet. 'I was wondering if you would mind...'

'You want me to go?'

'As senior investigating officer I should be there, but... well...'

The inspector had a little girl about the same age as the victim. Watching a four-year-old being filleted like a side of meat would be rough for him. All the same it wasn't a job Logan was looking forward to. Especially if Dr Isobel MacAlister was going to be the one doing the filleting. 'I'll go,' he said at last, trying not to sigh. 'You should probably be interviewing Chalmers anyway ... as senior investigating officer.'

'Thank you.' As a token of his esteem he gave Logan the last liquorice allsort.

Logan took the lift down to the morgue, hoping it would be Isobel's night off. Maybe he'd be lucky and get one of her deputies instead? But the way his luck was running he doubted it.

The morgue was unnaturally bright and airy for this time of night, the overhead lights sparkling off the dissecting tables and chiller cabinets. It was nearly as cold in there as it was outside. A heavy layer of disinfectant almost managed to hide the stench of corruption from this morning's post mortem. The smell of David Reid.

He arrived just in time to see the little girl being unloaded from her oversized body-bag. She was still wrapped in the packing tape, only now the shiny brown strips were dusted with white fingerprint powder.

Logan's heart sagged. It was Isobel, not one of her deputies, who stood on the far side of the stainless steel table, directing the little body into place. She was dressed in her cutting gear, the red rubber ap.r.o.n still clean and free from gore. The Procurator Fiscal and the corroborating pathologist were already there, dressed in coveralls, discussing the body with Isobel as she described the rubbish tip where it had been discovered.

She looked up as Logan approached, annoyance shining out from behind her safety goggles, and pulled down her surgical mask. 'I thought DI Insch was SIO on this case,' she said. 'Where is he this time?'

'He's interviewing the suspect.'

She snapped the mask back into place and muttered her displeasure. 'First he skips the David Reid post mortem and now he can't even be bothered to attend this one. I don't know why I b.l.o.o.d.y bother...' Her complaints trailed off into silence as she prepared her microphone and then went through the opening preliminaries. The Procurator Fiscal cast a disapproving glance at Logan. Clearly he agreed with Isobel's reading of the situation.

The shrill bleeping of Logan's mobile phone cut across her listing of those present and she hurled a furious scowl at him. 'I do not allow mobile phones to be used during my post mortems!'

Apologizing profusely, Logan dug the offending article out of his pocket and switched it off. If it was anything important they'd call back.

Still seething, Isobel finished off the introductory procedure, selected a pair of gleaming stainless steel scissors from the tray of instruments and began to snip away at the packing tape, doc.u.menting the state of the body as it was uncovered.

Underneath the tape, the little girl was naked.

A big chunk of hair threatened to come away as Isobel tried to unwrap the child's head. She loosened it with acetone, the sharp chemical smell cutting through the room's antiseptic tang and underlying perfume of decay. But at least this body hadn't been lying in a ditch for three months.

Isobel replaced the scissors on the tray and her a.s.sistant started packing the tape into labelled evidence bags. The body was still curled up in a foetal position. Gently Isobel worked the rigor out of the joints, flexing them back and forward until she could lay the little girl out flat on her back. As if she was just sleeping.

A blonde four-year-old girl, slightly overweight, with numerous bruises on her shoulders and thighs, the contusions dark on her waxy skin.

A photographer Logan didn't recognize was snapping away as Isobel worked.

'I'll need a good head and shoulders shot,' Logan told him.

The man nodded and perched over the cold, dead face.

Flash, whirr, flash whirr.

'There's a deep incision between the left shoulder and upper arm. It looks like...' Isobel pulled at the arm, opening up the deep gash. 'Yes: it goes all the way down to the bone.' She prodded the cut surfaces with a gloved finger. 'It was inflicted some time after death. A single blow from a sharp, flat blade. Possibly a meat cleaver.' She moved in so close to the incision that her nose was almost touching the dark-red flesh. She sniffed. 'There is a distinct smell of vomit in the region of the cut...' She stuck out a hand. 'Pa.s.s me those tweezers.'

Her a.s.sistant did as he was told and Isobel ferreted around in the wound, finally emerging with something grey and gristly.

'There are signs of partially-digested food in the wound.'

Logan tried not to picture the scene. Failed. 'He was trying to cut her up,' he sighed. 'Trying to get rid of the body.'

'And what makes you think that?' Isobel asked, one hand resting lightly on the little girl's chest.

'G.o.d knows there's enough talk of dismembered bodies in the papers. He wants to get rid of the evidence, so he tries to hack it up. Only it's not as easy as it sounds. Just trying it makes him sick.' Logan's voice was hollow. 'So he wraps her up in packing tape, stuffs her in a bin-bag and puts her out for the scaffies to take away.' In London they might be refuse disposal operatives, but in Aberdeen they were scaffies.

The Procurator Fiscal actually looked impressed. 'Very good,' he said. 'You may well be correct.' He turned to Isobel's a.s.sistant, Brian, who was busy popping the bits of gristle into a little plastic tube. 'Make sure that gets sent off for DNA a.n.a.lysis.'

Ignoring them, Isobel opened the child's mouth, peered in with a tongue depressor and recoiled. 'She appears to have ingested some form of household cleaner. Quite a lot of it from the state of her mouth. The teeth and skin all show signs of corrosive bleaching. We'll get a better idea when we get to the stomach contents.' Isobel closed the child's mouth with one hand, the other supporting the back of the blonde head. 'h.e.l.lo...' She beckoned the photographer closer. 'Take one of this. The back of the head has suffered a severe concussive blow.' Her fingers moved, probing the hair just above the spot where the skull met the neck. 'This wasn't a blunt object, but something wide that tapered to a point.'

'Like the corner of a table?' asked Logan, not liking where this was going.

'No, it would have to be sharp, solid, like the edge of a fireplace, or a brick.'
