‘The baby had been awake for most of the night,’ Ronald said. His face suddenly seemed very flushed and although it wasn’t hot in the room he’d started to sweat. ‘He had colic and made a sort of high-pitched squeal, like some kind of animal, a piglet maybe. You couldn’t sleep through it even if you tried. Anna was tense. Patient enough with the baby, but shouting at me every chance she had. I decided to go into Lerwick to the library and the supermarket. I thought I’d be better with a break from the bungalow. I got an earlier ferry back than I was expecting and called in to the big house on my way home. My father had had a phone call from Mima. Sandy had come to the island and she’d asked him to visit. Andrew was in a terrible state.’

‘So you offered to sort the matter out for him.’

‘Something had to be done!’ Ronald said, his voice unnaturally loud. ‘My father was making himself ill and scaring my mother. I said I’d go to see Mima, persuade her to be reasonable, offer her something.’ There was a silence. Perez waited for him to continue. Ronald went on, more calmly. ‘Back in the bungalow, I had dinner with Anna. Then she started having a go at me. About my drinking and the baby. I just couldn’t stand it. I had to get out of there. I said I was going after the rabbits.’

‘But you went to Setter.’

‘I was going to shoot rabbits,’ Ronald said. ‘Nothing was planned. But I kept going over and over it in my mind. What would happen if Mima started to rake up the past? So I went to see her.’

Again Perez remained silent. The lawyer stared at the inspector as if she wanted the questions to continue, so the interview would be over more quickly. Her hands fluttered nervously in her lap.
