By the time they arrived in Yell, Sandy had an address for them. Monica Leaze lived in Cullivoe, not too far from where the ferry came in. They turned off the main road and ahead of them the evening sky was red like flames, as if the sea was on fire. Everything was still. The banks on each side of the road were wild with flowers and grasses, the colours intense in the strange evening light. Willow was driving; she was too tense and fidgety to be a passenger.

When they found the house it was undistinguished, grey and small, a little ugly. There was no land attached, apart from a small square garden at the front, separated from the neighbour’s by a slatted wooden fence. There were other, newer homes along the same road. A couple were squat bungalows and the rest were Norwegian kit houses in coloured wood. Willow pulled the car into a passing place and they climbed out. Outside Monica’s front door stood a couple of terracotta pots, one containing mint and the other rosemary, but the lawn was overgrown. Willow opened the gate and knocked at the door.

No reply. Looking through the window, Perez thought the living room was too tidy. There was a Sunday paper neatly folded on a small table, but from the headline he could tell that it was at least a fortnight old. The cushions were piled symmetrically on the couch. It was oddly impersonal. No indication that an artist had lived here. No drawings on the wall. No paints. He stepped back a couple of paces and looked at the roof. There were Velux windows cut into the tiles, so perhaps Monica worked in the room in the attic.

An elderly woman was bringing in washing next door. She stood with a plastic basket at her feet, folding the clothes, but her eyes were fixed on the visitors. At last curiosity got too much for her and she came up to the fence. ‘Can I help you?’ She was all bone. Her face seemed to have been sculpted by the weather.

‘We’re looking for Monica Leaze.’

‘Nobody’s there. I haven’t seen her for a couple of weeks. She comes and goes, though. It’s more like a holiday place for her. I’m told she still has a house in London.’

Perez approached her. She’d probably respond better to his voice than to Willow’s. ‘Do you look after the place when she’s away?’

‘She never asked.’ Perez sensed there was no love lost between the neighbours. Had Monica, tense and anxious and used to the anonymity of the city, resented the intrusion of a bored, elderly woman? ‘Who are you?’

‘We’re police,’ he said. ‘Investigating the murders in Meoness.’
