‘Of course,’ Kai said. He drew himself up to his full height, stepped behind Irene’s shoulder and let her lead the way in.

All the ladies of leisure had congregated in one corner and were holding their coffee cups under their noses, whispering amongst themselves in a semi-panicked, semi-fascinated hissing. Their attention was undeniably on Silver, lounging at a vacant table on the other side of the room. Not surprising, given Silver’s reputation as one of London’s biggest libertines. A thin, pale-faced servant in grey stood behind him, holding Silver’s cane.

Silver himself was looking casually rakish, with his cravat knotted at his throat, his silver hair loose and his tanned skin golden against his white cuffs and collar. ‘Ah,’ he said on noticing Irene’s entrance. ‘Please join me.’ Another burst of whispering from the women on the other side of the cafe followed his words.

They seated themselves as Kai and Silver exchanged guarded glares.

‘Coffee?’ Silver suggested. ‘I would recommend a demitasse of the Bourbon blend.’

Kai looked ready to refuse on the spot, on principle, until he glanced at the menu. ‘Of course,’ he said with a thin smile.

Irene looked at the menu card surreptitiously. It was the most expensive brand of coffee listed.

‘My treat, of course,’ Silver began.

‘Please, Lord Silver,’ Irene said, before Kai could be undiplomatic. ‘We wouldn’t wish to put ourselves under an obligation towards you.’ Such things carried weight with the Fae.

Silver shrugged. ‘Can’t blame me for trying,’ he said, ‘although I give you my word there will be no obligation incurred for your coffee. Still, I believe this meeting will serve.’

‘Serve?’ Kai said. ‘You haven’t even said what this is about yet.’

‘Nor can I.’ Silver leaned forward, and his attitude of casual melodrama seemed to shift and fall away from him, leaving him quite serious. ‘If anyone asks, you can tell them it was about something to do with Vale. I have no objection to you linking his name with mine. But I’m here to discuss your future well-being.’

‘Threats?’ Kai sneered.

‘Oh, do leave that be,’ Silver sighed. ‘I had to get your attention somehow. It wasn’t as if I was actually trying to break into your house.’

Irene frowned. ‘Lord Silver, if this isn’t a threat, then what is it? Are you here to warn us about something?’

Silver glanced over his shoulder. ‘Johnson, fetch the coffee.’ He turned back to Irene. ‘No, no, of course not, we are just having a pleasant little conversation. Because if I were here to warn you about something, I would be breaking an oath that I have sworn, not to warn you about something. I trust we are all perfectly clear on this point?’

Irene and Kai exchanged glances. ‘Of course,’ Irene said smoothly. ‘We’re just drinking coffee together.’ She had been told the Fae were obliged to keep their oaths, but she’d never been in a position where it was really tested. If Silver was actually being truthful here, then they had even more to worry about than they’d thought.

‘Precisely.’ Silver looked relieved. ‘And please don’t think that this little coffee-drinking session is due to any actual affection for you, little mouse. You crashed my ball a few months back, you snatched a book out of my fingers, and you quite failed to mention that you were a representative of your Library. Any good guide to etiquette would mark you down on all three points.’

Irene raised her eyebrows. ‘As I remember it, you invited me to the ball, and the book was disputed property in any case.’

‘Finders keepers, I believe the legal term is,’ Kai put in smugly.

Silver glanced at him sidelong, the light catching his lavender eyes and making them glitter. ‘A person like you should be more careful,’ he said. ‘This sphere is hardly the most hospitable to your kind.’

Irene held up a hand before Kai could answer. ‘I thought we weren’t indulging in threats,’ she said coldly.

Silver studied her, as his servant placed cups of coffee on the table. ‘It is extremely difficult to suggest that you might possibly be in extreme peril without going to the extent of “warning” you,’ he finally said. ‘I’m simply having a cup of coffee with you, and suggesting that you might both want to be very careful. Why not take a little vacation to that Library of yours?’

Retreat to the Library was a sensible response to overt danger. Of course, this all hinged on Silver actually being reliable, which was far from certain.

‘Lord Silver,’ Irene said, picking up her cup. ‘You are the Ambassador from Liechtenstein, and to the best of my understanding that makes you one of the most powerful of your kind in London. Possibly even in England.’ Not entirely true. She’d heard stories of other creatures in the wilds of the British Isles - Wild Hunts, Faerie Courts and all that sort of thing - but it seemed a good moment to pour on the flattery. ‘But in the past we’ve been on opposite sides. Have we suddenly become allies, and I failed to notice it?’

‘Being my ally might have its advantages.’ Silver bared his teeth in a flashing smile. They were perfectly white, with just a suggestion of sharpness about them. Irene found herself wondering how they would feel against her wrist, the back of her hand, the side of her neck … He would be gentle, of course; she could tell from his eyes and his smile that he would be gentle, but at the same time he would be masterful, with the easy grace of control and skill and …
