As she climbed, she kept glancing behind at the shepherd’s shelter, but nobody approached it. She could only hope that she hadn’t been spotted, that the kidnapper, if that was what this was all about, wasn’t watching her through binoculars from a comfortable distance.

She found a spot she thought would do. It was a gentle dip in the daleside a few yards off the footpath. From there she could lie on her stomach and keep a close eye on the shelter without being seen from below.

Annie felt the warm, damp grass against her body, smelled its sweetness as she lay flat on her stomach, binoculars in hand. It felt good, and she wanted to take off all her clothes, feel the sun and earth on her bare skin, but she told herself not to be such a bloody fool and get on with the job. She compromised by taking off her jacket. The sun beat down on the back of her head and her shoulders. She had no suntan lotion with her, so she put the jacket over the back of her neck, even though it felt too hot. Better than getting sunstroke.

When she had got settled, there she lay. Waiting. Watching. Thoughts drifted through her head the way they did when she settled down to meditation, and she tried to practice the same technique of letting them go without dwelling on them. It started as a sort of free association, then went way beyond: sunlight; warmth; skin; pigment; her father; Banks; music; Luke Armitage’s black room; dead singers; secrets; kidnapping; murder.

Flies buzzed around her, snapping her out of the chain of association. She waved them away. At one point, she felt a beetle or some insect creeping down the front of her bra and almost panicked, but she managed to get it off her before it got too far. A couple of curious rabbits approached, twitched their noses and turned away. Annie wondered if she would end up in Wonderland if she followed one.

She took long, deep breaths of grass-scented air. Time passed. An hour. Two. Three. Still nobody came to pick up the briefcase. Of course, the shepherd’s shelter was off-limits because of foot-and-mouth, as was all open countryside, but that hadn’t stopped Martin Armitage, and she was certain it wouldn’t stop the kidnapper, either. In fact, it was probably why the place had been chosen: little chance of anyone passing by. Most people in the area were law-abiding when it came to the restrictions, because they knew how much was at stake, and the tourists were staying away, taking their holidays abroad or in the cities instead. Normally, Annie obeyed the signs, too, but this was an emergency, and she knew she hadn’t been anywhere near an infected area in weeks.

She wished she had something to eat and drink. It was long past lunchtime now, and she was starving. The heat was also making her thirsty. And there was something else, she realized, a more pressing urge: she needed to go to the toilet.
