Laura Rosewood pushed open the door and flicked on the electric light. They were standing in a sturdy single-storey, timber-clad building. Glazed doors with windows either side of it opened on to a decking area and a jetty at the end of which Horton could just about see a RIB, tossing wildly in the waves and wind. There was no sign of Thea inside or out. Damn. He needed to find her. He reached for his mobile but Laura prevented him.
'There's something you should know before you call for help.' She sat down and gestured Horton into a seat. When she saw he was reluctant to take it, she said, 'Thea couldn't have got far in this weather. And it's probably best you hear it all now before DCI Birch catches up with her.'
Reluctantly he perched on the edge of the wicker chair opposite.
She wrenched off her hat and with an anxious expression said, 'Owen confided something in me and Thea's just told me the rest. It's not a very happy story.'
'Go on,' he prompted when she stalled.
Taking a deep breath she said, 'Owen killed his parents. And Thea found out.'
It was just as he and Cantelli had worked out! He had hoped it wasn't true. He nodded at her to continue.
'Thea discovered that when Owen was a student at Southampton University he got a girl into trouble.'
This must have been the 'girl' that Thea had asked Bohman about.
Laura said, 'But it wasn't a simple case of pregnancy; the girl claimed that Owen had raped her. And before you ask, it never got as far as the police because Owen asked his parents to help him out. He wanted money to pay the girl off, a tart I believe, but one who had her head screwed on and very believable. You probably know the type, Inspector.'
Oh, he did. Lucy Richardson, who had accused him of rape, had been believed in all quarters, even by Catherine.
'Owen's parents refused to pay up though,' Laura continued. 'They said they would see her in court first. And Owen knew that it would ruin his life and his career.'
'And Owen confided this to you?'
She fiddled with her hat. 'Only about getting the girl pregnant. He said she had died in a road accident shortly after their affair but Thea told me the real story.' She looked up defiantly. 'Owen and I had a brief affair before he met Arina. That's why Thea came to me. She knew Owen and I had been close, and there was no one else she could turn to.'
She could have come to me. But then he was a policeman. He felt bitterly disappointed.
Laura continued. 'Thea told me that her brother had confessed to her that he couldn't let this girl destroy his life so he killed her in a hit-and-run accident. Yes, the same way that Arina died.'
'But Owen didn't kill Arina.'
'No, Jonathan Anmore did.'
Horton could see now the pattern of events.
Laura continued. 'I didn't know this of course until Thea told me an hour ago. You see, Owen thought Arina had discovered his secret, the one he'd do anything to protect. And though he loved her, he couldn't let her live knowing what he'd done — and besides, he knew she would no longer love him when she discovered the truth. He couldn't face that kind of rejection. Jonathan told Thea this at Arina's funeral-'
'Thea wasn't there,' Horton said quickly.
'She was, but not in the crowd of mourners. She kept her distance. I saw Jonathan cross to talk to her after the committal. I doubt he told her everything, probably because he didn't know it, but he must have said enough for Thea to become curious and concerned.'
Which was why, thought Horton, Thea had gone searching for answers in the library. It all added up.
He said, 'Did you get close to Steve Uckfield because you wanted to know how the investigation was progressing?'
'I was worried my affair with Owen would come out. I didn't want the newspapers to get hold of it so I called Reg and told him that Owen's death might have something to do with the environmental project he was working on. Well it was a possibility,' she added defensively. 'Reg said Steve Uckfield, his son-in-law, would be in charge, and I guessed he'd keep me informed.'
He eyed her keenly. There were still some questions he needed answers to before calling Uckfield. He couldn't bring himself to tell DCI Birch about Thea.
'Why did Owen kill his parents?'
Laura rose and crossed to the patio doors. Ramming her hands in her pockets she turned back to face him. 'I only have Thea's version of it but this is what she says Owen told her. His father heard about the girl's hit-and-run accident and accused Owen of killing her. They were very principled people and he said he was handing Owen over to the police, just what Owen didn't want. Owen smashed up their house and fixed their car to make it look as though they'd had an accident I'm not sure how he did it and neither is Thea. Maybe he didn't really mean to kill them, just to warn them, but…' She shuddered and drew her coat tighter around her.
Horton thought the summer house felt a few degrees colder. The wind howled around them, searching for gaps to squeeze through and chill them further. He recalled that cheerful voice he'd heard on the answer machine message, and found it hard to believe Owen Carlsson had ruthlessly killed a girl and his parents, though sadly as a police officer he knew those things happened.
Laura continued. 'Owen then had the girl off his back and his parents' money to help him through university. But poor little Thea was scarred for life by her parents' tragic death. After Jonathan had told Thea that Owen had paid him to kill Arina, Thea confronted her brother who, distraught over Arina's death even though he'd caused it, and guilt-ridden, told Thea everything, including how he'd killed their parents. Thea flipped, understandably so after the traumatic child hood she'd had. Filled with anger and hatred, she arranged for Jonathan to kill her brother, promising him half her inheritance. She said that Jonathan jumped at the chance.'
Horton knew the gardener had had financial difficulties.
'Then she killed Jonathan.' Laura shook her head sadly. 'Poor Thea is as mixed up as her brother clearly was. It's a mess and a tragedy.'
'What about her apartment? It was ransacked.'
'She did that to throw the scent off her.'
Horton rose and crossed to the window. Where was Thea now? Where had she been these last six days before showing up here? Had she returned there? Did Laura Rosewood know?
He turned back, his foot crunching on something as he did. Flicking his eyes down to see what it was, he heard Laura say, 'I thought I heard a noise outside. Thea must be trying to get away on the RIB. She's mad. She'll drown.'
She pushed past him, wrenching open the door, but Horton didn't follow.
'Why did Owen visit Dr Nelson?' he asked.
'Who? I don't know. Did he? I'm sure Thea is there.' And before Horton could stop her she was hurrying down the jetty.
Horton quickly moved after her. The sea was crashing on to the shore, spraying them both as it splashed over the jetty. He could hear it sucking up the stones underneath them as it retreated. The light from the summer house showed the waves breaking over the RIB. He could see no sign of Thea.
'Thea's not here,' he shouted above the roar of the sea and wind. 'She's never been here. Everything you said was a lie. It was convincing, Laura, I'll give you that. And I nearly fell for it. It will probably be enough to convince DCI Birch and maybe others, but not me.'
She halted and turned. He could see her wary expression.
'You killed Owen Carlsson,' he said. 'You shot him through the summer house window. There's glass on the floor, probably left from when you or Jonathan Anmore mended it. I take it Anmore helped you move the body. I can't see you managing that yourself. How did you get Owen to the Duver, Laura? Was it in Anmore's van or
