‘I was driving past and I saw them in the house, just shadows in my headlights. A woman’s been murdered here, and it looked as if Hillier was keeping her there against her will. Of course I was going to check that Polly was OK. She should never have been wandering around on her own.’ He looked at Marcus. Accusing: You should be taking better care of your woman.

‘And was Mr Hillier being unreasonable?’ Willow again.

Polly shook her head. ‘He was just being weird. I probably shouldn’t have been there, but I wasn’t doing any harm and he seemed to overreact big-style. Then Ian turned up and things started getting a bit fraught, so we just left.’ She hesitated. ‘Hillier said there was some connection between the house and the ghost that Eleanor claimed to have seen.’ She turned to Lowrie. ‘Did you know anything about that?’

Lowrie shrugged. ‘The croft house was in our family,’ he said. ‘The lass looking after Lizzie Geldard lived there. Then my grandfather built our house on a bit of the land, and later Vaila and her man built their new place next door, and the old house was just left to ruin. It was a shame. I thought Vaila’s husband might renovate and extend the old place, but I suppose it would have cost more in the end than starting from scratch.’ He hesitated. ‘And there’s always been a kind of superstition about the building. Maybe they thought it would be bad luck to tear it down.’

‘Is it ever used?’ Willow asked.

‘Maybe for storage, but probably not even for that now, it’s such a damp old place.’

Perez thought Polly was about to speak again, but she turned towards the window and said nothing.

‘What did you do last night when you got back here?’ Willow asked.

‘I cooked supper,’ Polly said. ‘There was heaps, so we phoned Lowrie and Caroline and asked them to join us. It was good to get together to remember Eleanor. Somehow she seems to have got lost in all this.’

‘And then?’

‘Then the others wanted to go out. I stayed here.’ She paused and smiled at Ian. ‘Ian was worried about me, but I felt quite safe. There are locks on the doors and my mobile has reception. I promised I’d phone if anything worried me. We’ve all been shut in together since Eleanor died and I longed for some time on my own.’

‘Where did the rest of you go?’
