Patience poured half a small bottle of tonic water into her gin, while Rebus supped on a pint of IPA.

‘Cheers,’ she said, without enthusiasm. Then: ‘I know damned fine that there’s got to be a reason for this. I mean, a reason why we’re here. I suppose it’s to do with your work?’

Rebus put down the glass. ‘Yes,’ he said.

She raised her eyes to the nicotine-coloured ceiling. ‘Give me strength,’ she said.

‘It won’t take long,’ Rebus said. ‘I thought afterwards we could go somewhere . . . a bit more your style.’

‘Don’t patronize me, you pig.’

Rebus stared into his drink, thinking about that statement’s various meanings. Then he caught sight of a new customer in the bar, and waved through the doorway. A young man came forwards, smiling tiredly.

‘Don’t often see you in here, Inspector Rebus,’ he said.

‘Sit down,’ said Rebus. ‘It’s my round. Patience, let me introduce you to one of Scotland’s finest young reporters, Chris Kemp.’

Rebus got up and headed for the bar. Chris Kemp pulled over a chair and, having tested it first, eased himself on to it. ‘He must want something,’ he said to Patience, nodding towards the bar. ‘He knows I’m a sucker for a bit of flattery.’

Not that it was flattery. Chris Kemp had won awards for his early work on an Aberdeen evening paper, and had then moved to Glasgow, there to be voted Young Journalist of the Year, before arriving in Edinburgh, where he had spent the past year and a half ‘stirring it’ (as he said himself). Everyone knew he’d one day head south. He knew it himself. It was inescapable. There didn’t seem to be much left for him to stir in Scotland. The only problem was his student girlfriend, who wouldn’t graduate for another year and wouldn’t think of moving south before then, if ever . . .

By the time Rebus returned from the bar, Patience had been told all of this and more. There was a film over her eyes which Chris Kemp, for all his qualities, could not see. He talked, and as he talked she was thinking: Is John Rebus worth all this? Is he worth the effort I seem to have to make? She didn’t love him: that was understood. ‘Love’ was something that had happened to her a few times in her teens and twenties and even, yes, in her thirties. Always with inconclusive or atrocious results. So that nowadays it seemed to her ‘love’ could as easily spell the end of a relationship as its beginning.

She saw it in her surgery. She saw men and women (but mostly women) made ill from love, from loving too much and not being loved enough in return. They were every bit as sick as the child with earache or the pensioner suffering angina. She had pity and words for them, but no medicines.

Time heals, she might say in an unguarded moment. Yes, heals into a callus over the wound, hard and protective. Just like she felt: hard and protective. But did John Rebus need her solidity, her protection?
