Inside, Perez sat opposite Sarah Fowler and tried to find a way to make her relax. He felt constrained; perhaps it was the name, but she reminded him too much of his first wife to push her for answers about Angela Moore’s death. It wasn’t her physical appearance – his Sarah had been softer and rounder – but the air of anxiety, unhappiness even, that she carried around her. Her tension was contagious and when he took up a pen to make notes he saw his own hand was trembling slightly.

‘I’m sorry to have disrupted your holiday like this.’

She looked up sharply. It wasn’t what she’d been expecting.

‘You didn’t commit the murder, Inspector. You’re just doing your job.’ The words sounded brusque but he thought she was abrupt only because she was so nervous. He understood why her husband felt the need to protect her.

‘Has it been very awkward for you to extend your stay? I presume you too have work to get back to. Or are you involved in your husband’s business?’ To Perez, this felt less like a formal interview than an attempt to make small talk with a reluctant stranger.

‘Good lord, no! He hardly earns enough from selling books to keep himself.’ She paused. ‘I manage a Sure Start children’s centre on a council estate in Bristol. Challenging but I enjoy it.’ She paused. ‘At least until recently, when things got on top of me. The management thing is rather stressful, though the children make up for the bureaucratic hassle. I have great staff. They’ll cope without me.’

He stumbled to find something to say. The loss of a baby must have been almost unbearable for a woman who so much enjoyed the company of children. He found it hard to imagine this shy woman in charge of a bustling, noisy centre.

As if she was reading his mind she continued. ‘They’re used to managing without me. I’ve had a couple of months off work sick this year. Depression.’

‘I’m sorry.’

‘My husband and I have been under a lot of pressure recently, Inspector. This holiday was an attempt to mend the relationship, bring us back together. I wasn’t sure coming to Fair Isle was a good idea. John’s rather a figure of fun in the birdwatching world. He made a couple of highly publicized mistakes. Embarrassing when previously he had such a high profile. I know I shouldn’t care what people think but I find all that more awkward than he does. But we’d enjoyed our stay very much until Angela died.’

She looked up at him. He saw she was waiting for the real questions to begin. Perez would have liked to know more about the events that had brought the couple to the island, but of course he should move on.

‘Did you know Angela Moore before you came to Fair Isle?’
