‘So perhaps he wanted to believe.’ Perez hoped he was making sense. He felt he was groping towards some sort of answer. ‘Perhaps he wanted the whole conversion experience. To please Annabel and the rest of them. To become the centre of attention again.’

‘Then why did he come back to Shetland?’ Willow was sitting on the floor, though there were chairs enough for the three of them. She was stretched on a couple of sheepskins in front of the fire and her face was red with the heat. She’d taken off her sweater and was wearing a striped T-shirt, frayed at the neck. ‘Why did he run away from his new girlfriend and all his new friends and bring himself back here?’

‘To tell his parents that he was going to be married?’ Perez remembered Maria’s insistence that Jerry had something important to tell her. ‘But not just that. He’d have told them straight away, if that was the sole reason for the visit.’

‘Could it be that he was here to write a story, like he told everyone?’ Sandy had been following the conversation, frowning with concentration. ‘When he was working on the Shetland Times perhaps he’d come across something in the islands that wasn’t right. I don’t know – corruption. People on the fiddle. And this was his chance to prove to his new friends that he was a good man. A good Christian.’

‘Or perhaps the conversion thing was all bollocks,’ Willow said. ‘He went along with it to get inside Annabel’s knickers. And he was here to make a bit of money to impress his new woman. Perhaps the blackmail theory still holds.’

There was a silence. Perez got to his feet to pour more coffee. He had ideas about the case – he always believed more in the personal than the political – but it was Willow’s place to move the investigation forward. In the end she threw the responsibility back to him.

‘What do you think, Jimmy? Where do we go next?’

‘I’d like to talk to Evie again,’ he said. ‘If Markham’s change of heart was genuine, then Evie would be the person he’d feel the need to meet. He’d want her forgiveness, wouldn’t he? He’d want to set things straight between them, before going back to start his new life with Annabel Grey.’ Perez drained his mug and ran again in his head the conversations he’d had with Evie Watt. ‘She told me Markham had tried to phone her, but she claims that she hadn’t met him. Perhaps we need to check that. Evie looks young, right enough, but perhaps Sue Walsh was mistaken, and Evie was the woman Markham met at the Bonhoga.’

‘So that’s your plan for tomorrow, Jimmy?’
