Campbell glanced at the distant cameras in disbelief. ‘They’re miles away! Of course they can’t hear you, but they can see you. They’ve got a socking great zoom on that camera and it’s pointed straight at you so, for God’s sake, pull yourself together!’ he told her sharply. ‘You’re making yourself look ridiculous.’

And him by association.

‘Better to be ridiculous than splattered all over the bottom of this cliff!’

A muscle was jumping in his cheek and his jaw looked suspiciously set. ‘For a start, this is not a cliff,’ he said with the kind of restraint that suggested that he was only hanging on to his temper with extreme difficulty. ‘It’s barely twenty feet to the bottom there and, as I keep telling you, you’re not going to fall. You’re on a secure rope, and you can let yourself down slowly. Even if you did lose control, I’ve got hold of the rope and I’d stop you dropping.’

‘You might not be able to,’ said Tilly, not at all convinced. ‘That rope’s awfully fine. I can’t believe it’ll hold my weight.’

‘Of course it will,’ he said impatiently. ‘This rope could hold a hippopotamus.’

‘Now, I wonder what made you think of a hippo,’ Tilly said bitterly.

She wished Campbell hadn’t mentioned the zoom on that camera. It was probably trained on her bottom right now. Unsure of quite what ‘a day in the hills’ involved, but fairly sure it would mean getting cold, she had squeezed herself into her old skiing salopettes, bought in a burst of enthusiasm soon after she had met Olivier and was at least two sizes smaller. Now her big red bottom would be filling the screen down there, and the television crew would all be having a good laugh.

Tilly had a dark suspicion that had been the idea all along.

‘Who thought up this show in the first place?’ she demanded, fear and humiliation giving her voice a treacherous wobble, but at least talking took her mind off the void beneath her.
