And now Ben felt the familiar old sense of suspiciousness come flooding back, and he regretted his initial response. He had spent years travelling all over the world under a variety of fake identities, both during and after his time in British Special Forces. Nowadays he was just an ordinary citizen, or as ordinary as a man like him could ever be, and he seldom had cause to travel using any identity other than his own. But he still didn’t like being recognised like this. And whoever the well-dressed stranger was, he obviously hadn’t come to ask the time.

Ben replied tersely, ‘I’m sorry, I think you got the wrong person. I don’t know any Mr Hope.’

The stranger’s face crinkled into a polite smile. But there was a falseness to it, a coldness behind his eyes that made the curl of his lips seem unpleasantly knowing, almost mocking. ‘I do beg your pardon. What I should have said was “Enjoying your trip, Major Hope?” Because, you see, I do happen to know exactly who I’m speaking to. I might add that it’s a pleasure to make your acquaintance. By all accounts you’re really quite a remarkable fellow.’

Ben stared at the stranger for a very long time. He said, ‘There are plenty of other free seats on this plane. You might want to go and sit in one of those instead.’

The mock-polite smile again. ‘Don’t be coy, Major. A man with your record, which, by the way, makes fascinating reading, should be proud of his achievements. More than a dozen years serving your country in our most elite military force, responsible for countless successful missions in theatres of war all over the world, involving some quite outstanding displays of strategic brilliance and courage. I’m sure I needn’t run through a whole summary of your exemplary career, though.’

The stranger couldn’t be bluffing. He seemed to know too much for that. But if he really had read Ben’s military file, that meant he had access to high-level classified information. Which in turn meant he wasn’t just anybody. He was also talking far too openly about matters that were not meant to be public knowledge.

Ben glanced around him at all the vacant seats, and wondered whether it was just a coincidence that he’d been seated in an almost empty section. Whoever had arranged this cosy meeting could easily have made ghost reservations for half the plane, ensuring that the conversation would not be overheard. And Ben had let himself be caught right in their trap. He felt angry and powerless.

‘All right,’ he said to the stranger. ‘You’ve seen my record, and you know who I am. Which means you’re obviously bothering me for a reason.’

‘You’re quite correct. I thought we could have a little chat before you got home. Easier this way.’
