And that he didn't know where Thea was. And if the forensic team could prove Danesbrook's car had been at St Helens Duver, and near Anmore's barn, then they'd have him. Horton called Uckfield and quickly briefed him.
'I'll have a go at him,' Uckfield said with relish. Horton could almost see him rubbing his hands. 'You and Cantelli get down to the mortuary. Dr Clayton says she's finished the autopsy on Anmore. See if she can give us something that we can nail the bastard with, because he's the only bloody suspect we've got.'
Horton was inclined to agree but he said, 'What about Terry Knowles?'
'His office confirms he was on a field study with a group of university students at the time of Owen Carlsson's death, all of whom could verify it if asked.'
'And when Arina Sutton was killed?'
'Why the hell should he want to kill her? He doesn't even know her.'
'We can't be sure of that.'
'OK, we'll ask him when he emerges from the mountains.'
Horton didn't know if they had mountains on the Shetland Islands. He guessed Uckfield was right about Knowles though. He doubted he had killed anyone.
Uckfield said, 'Laura Rosewood phoned to say that Carlsson hadn't sent any of his findings to Knowles' office by email, and neither had he sent them to the European Translation Agency.'
That meant Thea wasn't being threatened because of it. But there was still that link between Arina Sutton and the Carlsson parents being killed in the same place which troubled him like an itch that could not be scratched. For now though he pushed it to the back of his mind and with Cantelli headed for the mortuary.
FOURTEEN
' Coffee?' Gaye Clayton said, meeting them in the corridor outside the mortuary. 'They've got a decent machine here.'
Horton agreed with alacrity. He felt in need of a caffeine boost and a desire to wash the taste of Danesbrook from his mouth. Eradicating the smell of his body odour might take longer, however. Danesbrook brought a whole new meaning to the term shit-scared — or was it bullshit Horton had smelt? Uckfield had better have the air freshener ready.
Gaye pressed some buttons on a machine. As the coffee beans were ground noisily she continued. 'The victim died from stab wounds caused by the pitchfork. It penetrated the heart, and caused internal bleeding, and hence death. There was no evidence of the paint being in the stab wounds, which means it was poured over the victim after death. I've taken photographs both before and after I removed the pitchfork, which I had to do at the scene of crime, and the mortuary assistant is loading them on to the computer in the main office, as we speak. I'll then be able to study the images more closely.'
Cantelli took the paper cup from her. 'And the anti-fouling paint?'
'Interesting. From my examination — and it was a messy one — it was poured over him, starting from the back of the head and then down to the ankles. You might have noticed that there was less on his ankles and none, except splashes, on his outstretched arms.'
Horton had. As he took his coffee from her she said, 'Come through to this cupboard they call an office.'
She waved Horton into a seat opposite the kind of desk he thought you only ever saw in furniture stores or advertisements: pristine clean and devoid of all paperwork. On it though was a laptop computer — Gaye's he guessed — and a telephone. Her own office in Portsmouth was probably groaning under the strain of paper, as his must be by now. He'd be back there on Wednesday unless this investigation dragged on. He was hopeful that later today, with some pressure applied, Danesbrook might confess to his part in the murders and give them the name of his accomplice.
Cantelli squeezed himself into the cubbyhole and leant against a filing cabinet to Horton's right. Slipping his chewing gum into a piece of paper and popping it in his pocket, he asked, 'Why pour the paint over him?'
It was a question that Horton had been asking himself. Somehow that didn't fit with Danesbrook, though it could his partner-in-crime, he supposed.
Gaye slumped into the swivel chair opposite Horton. He saw the dark smudges under her eyes. 'Some kind of gesture, I guess?' she said. 'Anger, jealousy. Perhaps after stabbing him, the killer picked up the first thing to hand. If your victim had been married I might have said it was a jealous wife who resented playing second fiddle to the boat.'
Cantelli glanced at Horton. 'Does that mean we're back to considering the jealous husband or boyfriend of one of Anmore's clients out for revenge? Or could Danesbrook have got jealous?'
'You mean he's gay? You're the second person to suggest that.' Horton considered it briefly. 'I wouldn't have said he was, though who knows.'
'Danesbrook?' queried Gaye.
'Someone we've pulled in for questioning — and you were right about Arina Sutton, she was the daughter of Sir Christopher Sutton, your neuropsychiatric consultant. He's dead. Cancer,' Horton quickly added.
She heaved a sad sigh which turned into a yawn before sipping her coffee.
Horton again considered the paint and his and Uckfield's earlier conversation with Laura Rosewood. He had another theory. Admittedly it was a bit off beam but he might as well toss it in with everything else.
To Gaye he said, 'We've been told that Owen Carlsson could have been killed because he was working on an environmental project which involved not only mapping the coastal erosion hazards, but analysing the state of the sea around the Isle of Wight.'
Gaye eyed him keenly. 'You mean the anti-fouling paint was used as a kind of protest statement because it isn't environmentally friendly — well, not entirely,' she said, grasping his point at once. He should have known she would.
'What's wrong with it?' asked Cantelli.
'Shall I explain?' Gaye Clayton said eagerly.
'Be my guest.'
'Anti-fouling marine paint contains a biocide or poison held in the coating, which when on a boat's hull, leaches slowly from the paint straight into the marine environment. It's used to prevent larvae, barnacles, mussels and seaweed spores attaching themselves to a boat's hull, which would slow a boat down.'
She glanced at Horton who took up the explanation. 'Anti-fouling paint can have a harmful effect not just on the organisms trying to foul the hull, but on marine life. And that was Owen Carlsson's speciality.' He recalled reading somewhere how toxins from the paint can settle in the sea affecting a host of tiny creatures which made up the marine food chain. 'Owen Carlsson was studying the sea around the island for a European project. Maybe he discovered that a manufacturer of anti-fouling paint was using a new and more potentially harmful variety or one that hadn't been fully tested.'
'But why kill Anmore? He wasn't conducting a study,' said Cantelli, clearly baffled. He wasn't the only one.
Horton said, 'Perhaps Owen had uncovered fresh evidence that showed beyond all doubt this new paint was a major hazard to marine life, which if exposed would be a serious threat to sales, internationally. He's killed to silence him and then his house flashed up to destroy the evidence, but Anmore witnesses Owen's death, or is involved in it, or perhaps Owen told him when they got to talking about boats.'
Cantelli was looking at him as if he'd just read him a Brothers Grimm fairy tale. Horton shrugged and shaped a grin. 'Yeah, it's a bit weak.'
SOCO would already have bagged up the tin of paint and Horton made a mental note to have it analysed but along with the theory that Owen had possibly been involved with a property development company or marina who wanted his findings stopped, it wasn't really a very strong motive. Danesbrook's greed was far more plausible.
Cantelli's phone rang. He ducked out of the office to answer it as Horton addressed Dr Clayton. 'What was the time of death?'
'Between six and eight p.m. last night.'
When Danesbrook had no alibi, thought Horton more cheerfully.
Gaye said, 'The victim didn't put up a struggle. I found a contusion on the back of the head. He was struck
