Exit Music by Ian Rankin (Orion Books 2007)

'No one's about to poison me, Rebus. Sergei and me, we see things the same way. Few years from now, Scotland's going to be independent - not a shred of doubt about that. Sitting on thirty years' worth of North Sea oil and God alone knows how much more in the Atlantic. Worst-case scenario, we do a deal with Westminster and end up with eighty or ninety per cent of the cut.' Cafferty gave a slow shrug. 'And then we'll goand spend the money on our usual leisure pursuits - booze, drugs and gambling. Put a supercasino in every city, and watch the profits stack up . . .'
'Another of your silent invasions, eh?'
'Soviets always did think there'd be revolution in Scotland. Won't matter to you, though, will it? You'll be out of the game for good.' Cafferty gave a little wave of the hand and turned his back.
