‘Anna Clouston had her baby last night,’ Mima said. ‘A difficult birth apparently. She was in labour for twenty hours. They’re going to keep her in for a few days to keep an eye on her. It was a boy. Another man to take on the Cassandra.’ She shot a conspiratorial look at Hattie. It seemed to amuse Mima that Anna had had a difficult labour. Mima liked chaos, disorder, other people’s misfortune. It gave her something to gossip about and kept her alive. That was what she said, at least, when she sat in her kitchen cackling into her tea or whisky, filling Hattie in on island events.

Hattie didn’t know what to say about Anna Clouston’s child – she’d never seen the appeal of babies and didn’t understand them. A baby would just be another complication. They were standing at Setter, in the field at the back of the house. A wash of spring sunshine lit the makeshift windbreak of blue plastic, the wheelbarrows, the trenches marked with tape. Seeing it as if for the first time, Hattie thought what a mess they’d made of this end of the croft. Before her team from the university had turned up, Mima had looked out over sloping low meadow to the loch. Now, even at the beginning of the season the place was muddy as a building site and Mima’s view was interrupted by the spoil heap. The wheelbarrow run had scored ruts in the grass.

Hattie looked beyond the disturbance to the horizon. It was the most exposed archaeological site she’d ever worked. Shetland was all sky and wind. There were no trees here to provide shelter.

I love this place, she thought suddenly. I love it more than anywhere else in the world. I want to spend the rest of my life here.

Mima had been pinning towels on to the washing line, surprisingly supple despite her age. She was so small that she had to stretch to reach the line. Hattie thought she looked like a child, prancing on tiptoes. The laundry basket was empty. ‘Come away in and have some breakfast,’ Mima said. ‘If you don’t put on a bit of weight you’ll blow away.’
