Quickly, I open a new document, invent a fancy letterhead and type a letter from a Mr Ernest P. Leopold to the Panther Corporation. I send it over to print, stroll over to the printer and whisk it out before anyone else can see what it is. Not that anyone else is remotely interested.

'Right,' I say casually, tucking it into the cardboard folder. 'Well, I'll just take that file up, then …'

Artemis doesn't even raise her head.

As I walk along the corridors my stomach is churning, and I feel all prickly and self-conscious, as though everyone in the building must know what I'm doing. There's a lift waiting to go up, but I head for the stairs, firstly so I won't have to talk to anyone and secondly because my heart's beating so fast, I feel like I need to use up a bit of nervous energy.

Why does Jack Harper want to see me? Because if it's to tell me he was right all along about Connor, then he can just … he can just bloody well … Suddenly I have a flashback to that awful atmosphere in the lift, and my stomach turns over. What if it's really awkward? What if he's angry with me?

I don't have to go, I remind myself. He did give me an out. I could easily phone his secretary and say, 'Sorry, I couldn't find the Leopold file,' and that would be the end.

For an instant I hesitate on the marble stairs, my fingers tightly clutching the cardboard. And then I carry on walking.

As I near the door of Jack's office I see that it's being guarded not by one of the secretaries, but by Sven.

Oh God. I know Jack has said he's his oldest friend, but I can't help it. I do find this guy creepy.

'Hi,' I say. 'Er … Mr Harper asked me to bring up the Leopold file.'

Sven looks at me, and for an instant it's as if a little silent communication is passing between us. He knows, doesn't he? He probably uses the Leopold file code himself. He picks up his phone and after a moment says, 'Jack, Emma Corrigan here with the Leopold file.' Then he puts down the phone, and without smiling, says, 'Go straight in.'

I walk in, feeling prickly with self-consciousness. The room is huge and panelled, and Jack's sitting behind a big wooden desk. When he looks up, his eyes are warm and friendly, and I feel myself relax just the teeniest bit.

'Hello,' he says'.

'Hello,' I reply, and there's a short silence.

'So, um, here's the Leopold file,' I say, and hand him the cardboard folder.

'The Leopold file.' He laughs. 'Very good.' Then he opens it and looks at the sheet of paper in surprise. 'What's this?'

'It's a … it's a letter from Mr Leopold of Leopold and Company.'

'You composed a letter from Mr Leopold?' He sounds astonished, and suddenly I feel really stupid.

'Just in case I dropped the file on the floor and someone saw,' I mumble. 'I thought I'd just quickly make something up. It's not important.' I try to take it back, but Jack moves it out of my reach.

'"From the office of Ernest P. Leopold",' he reads aloud, and his face crinkles in delight. 'I see he wishes to order 6,000 cases of Panther Cola. Quite a customer, this Leopold.'

'It's for a corporate event,' I explain. 'They normally use Pepsi, but recently one of their employees tasted Panther Cola, and it was so good …'

'They simply had to switch,' finishes Jack. '"May I add that I am delighted with all aspects of your company, and have taken to wearing a Panther jogging suit, which is quite the most comfortable sportswear I have ever known."' He stares at the letter, then looks up with a smile. To my surprise, his eyes are shining slightly. 'You know, Pete would have adored this.'

'Pete Laidler?' I say hesitantly.

'Yup. It was Pete who came up with the whole Leopold file manoeuvre. This was the kind of stuff he did all the time.' He taps the letter. 'Can I keep it?'

'Of course,' I say, a little taken aback.

He folds it up and puts it in his pocket, and for a few moments there's silence.

'So,' says Jack at last. He raises his head and looks at me with an unreadable expression. 'You broke up with Connor.'

My stomach gives a flip. I don't know what to say.

'So.' I lift my chin defiantly. 'You decided to stay.'

'Yes, well …' He stretches out his fingers and studies them briefly. 'I thought I might take a closer look at some of the European subsidiaries.' He looks up. 'How about you?'

He wants me to say I chucked Connor because of him, doesn't he? Well, I'm not going to. No way.

'Same reason.' I nod. 'European subsidiaries.'

Jack's mouth twitches reluctantly into a smile.

'I see. And are you … OK?'

'I'm fine. Actually, I'm enjoying the freedom of being single again.' I gesture widely with my arms. 'You know, the liberation, the flexibility …'

'That's great. Well then, maybe this isn't a good time to …' He stops.

'To what?' I say, a little too quickly.
