From the way his face jolts in surprise as he sees me, I guess he’s wondering the same thing.

I am so busted. Why did I think I could get away with gate-crashing a big posh party like this?

My face is flaming with embarrassment. I quickly try to back away, but the mass of people pressing behind me is too heavy, so I’m stuck, staring mutely up at him.

“When Sam’s in the room, you know things will reach resolution,” the blond woman is saying. “Whether it’s the resolution you want … eh, Charles?” There’s a roar of laughter around the room, and I hastily join in with fake gusto. Clearly this is a massive in-joke, which I would know about if I weren’t a gate-crasher.

The guy next to me turns and exclaims, “She’s a bit near the knuckle there!” and I find myself replying, “I know, I know!” and giving another huge phony laugh.

“Which brings me to another key player … ”

As I lift my eyes, Sam is looking nowhere near me, thank God. This is excruciating enough as it is.

“Let’s hear it for Jessica Garnett!”

As a girl in red steps onto the podium, Sam takes his phone out of his pocket and unobtrusively taps at it. A moment later a text bleeps in my phone.

Why were you laughing?

I feel a stab of mortification. He must know I was just trying to blend in. He’s deliberately winding me up. Well, I’m not going to rise.

It was a good joke.

I watch as Sam checks his phone again. His face twitches only the tiniest bit, but I know he got it. He types again briefly—then a moment later my phone bleeps again.

I didn’t know your name was on my invitation.

I glance up in trepidation, trying to gauge his expression, but again he’s looking in the other direction, his face impassive. I think for a moment, then type:

Just stopped by to collect your goody bag for you. All part of the service. No need to thank me.

And my cocktails, I see.

Now he’s looking right at my cosmo. He raises his eyebrows and I suppress an urge to giggle.

I was going to put them in a hip flask for you. Obviously.

Obviously. Although mine’s a Manhattan.

Ah, well, now I know. I’ll chuck all those tequila shots I had saved up.

As he clocks this last message, Sam looks up from his phone and flashes me that sudden smile. Without meaning to, I find myself beaming back and even catch my breath a little. It really does something to me, that smile of his. It’s disconcerting. It’s …

Anyway. Concentrate on the speech.

“ … and, finally, have a great night tonight! Thanks, everyone!”

As a final round of applause breaks out, I try to find an escape route, but there isn’t one. Within approximately ten seconds, Sam has stepped straight down off the podium and is standing in front of me.

“Oh.” I try to hide my discomfiture. “Er … hi. Fancy seeing you here!”

He doesn’t reply, only looks at me quizzically. There’s no point trying to brazen this out.

“OK, I’m sorry,” I say in a rush. “I know I shouldn’t be here, it’s just I’ve never been to the Savoy, and it sounded so amazing, and you didn’t want to go, and—” I break off as he lifts a hand, looking amused.

“It’s no problem. You should have told me you wanted to come. I would have put you on the list.”

“Oh!” The wind is taken out of my sails. “Well … thanks. I’m having a really nice time.”

“Good.” He smiles and takes a glass of red wine from a passing waiter’s tray. “You know what?” He pauses thoughtfully, cradling his glass in his hands. “I have something to say, Poppy Wyatt. I should have said it before. And that’s thank you. You’ve been a great help to me, these past few days.”

“It’s fine, really. No problem.” I hurriedly make a brushing-off motion, but he shakes his head.

“No, listen, I want to say this. I know originally I was doing you the favor—but in the end you’ve done me one. I haven’t had any proper PA support at work. You’ve done a great job, keeping me up-to-date with everything. I appreciate it.”

“Honestly, it’s nothing!” I say, feeling uncomfortable.

“Take the credit!” He laughs, then shrugs off his jacket and loosens his tie. “Jesus, it’s been a long day.” He slings his jacket over his shoulder and takes a gulp of wine. “So, nothing up today? The airwaves have gone very quiet.” He gives another of those devastating little smiles. “Or are all my emails coming through to Jane now?”

My phone contains two hundred and forty-three emails for him. And they’re still coming in.

“Well … ” I take a gulp of cosmo, desperately playing for time. “Funnily enough, you did get a few messages. I thought I wouldn’t disturb you while you were in Germany.”

“Oh yes?” He looks interested. “What?”

“Um … this and that. Or would you rather wait till tomorrow?” I clutch at a last hope.

“No, tell me now.”

I rub my nose. Where do I start?

“Sam! There you are!” A thin guy in glasses is approaching. He’s blinking quite fast and holding a large black portfolio under his arms. “they said you weren’t coming tonight.”

“I wasn’t,” Sam says wryly.

“Great. Great!” The thin guy is twitching with nervous energy. “Well, I brought these along on the off chance.” He thrusts the portfolio at Sam, who takes it, looking bemused. “If you have a moment tonight, I’ll be staying up till two or three, always happy to Skype from home… . A bit radical, some of it, but … Anyway! I think it’s a great thing you’re doing. And if there is a job opportunity behind all this … count me in. Right. Well … I won’t keep you any longer. Thanks, Sam!” He darts away again into the crowd.

For a moment neither of us speaks, Sam because he looks too baffled and me because I’m trying to work out what to say.

“What was all that about?” says Sam at last. “Do you have any idea? Is there something I’ve missed?”

I lick my dry lips nervously. “There was something I meant to tell you about.” I give a high-pitched laugh. “It’s quite funny, actually, if you see it that way—”

“Sam!” A large woman with a booming voice interrupts me. “So delighted we’ve got you signed up for the Fun Run!” Oh my God. This must be Rachel.

“Fun Run?” Sam echoes the words as though they’re complete anathema to him. “No. Sorry, Rachel. I don’t do Fun Runs. I’m happy to donate, let other people do the running, good for them—”

“But your email!” She stares at him. “We were so thrilled you wanted to take part! No one could believe it! This year we’re all running in superhero costumes,” she adds enthusiastically. “I’ve earmarked a Superman one for you.”

“Email?” Sam looks bewildered. “What email?”

“That lovely email you sent! Friday, was it? Oh, and bless you for the e-card you sent young Chloe.” Rachel lowers her voice and pats Sam on the hand. “She was so touched. Most directors wouldn’t even care if an assistant’s dog had died, so for you to send such a lovely e-card of condolence, with a poem and everything … ” She opens her eyes wide. “Well. We were all amazed, to be honest!”

My face is getting hotter. I’d forgotten about the e-card.

“An e-card of condolence for a dog,” says Sam at last, in a strange voice. “Yes, I’m pretty amazed at myself.”

He’s staring straight at me. It’s not the most friendly of expressions. I fact, I feel like backing away, only there’s nowhere to go.

“Oh, Loulou!” Rachel suddenly waves a hand across the room. “Do excuse me, Sam.” She heads off, pushing her way through the throng, leaving us alone.

There’s silence. Sam regards me evenly, without a flicker. He’s waiting for me to start, I realize.

“I thought … ” I swallow hard.

“Yes?” His voice is curt and unforgiving.

“I thought you might like to do a Fun Run.”

“You did.”

“Yes. I did.” My voice is a little husky with nerves. “I mean … they’re fun! So I thought I’d reply. Just to save you time.”

“You wrote an email and signed it as me?” He sounds thunderous.

“I was trying to help!” I say hurriedly. “I knew you didn’t have time, and they kept asking you, and I thought—”

“The e-card was you too, I take it?” He shuts his eyes briefly. “Jesus. Is there anything else you’ve been meddling in?”

I want to bury my head like an ostrich. But I can’t. I have to tell him, quickly, before anyone else accosts him.

“OK, I had this … this other idea,” I say, my voice barely above a whisper. “Only everyone got a bit carried away, and now everyone’s emailing about it, and they think there’s a job involved—”

“A job?” He stares at me. “What are you talking about?”

“Sam.” A guy claps him on the back as he passes. “Glad you’re interested in coming to Iceland. I’ll be in touch.”

“Iceland?” Sam’s face jerks in shock.

I’d forgotten about accepting the Iceland trip too.68 But I only have time to make another apologetic smile before someone else is accosting Sam.

“Sam, OK, I don’t know what’s going on.” It’s a girl with glasses and a very intense way of speaking. “I don’t know if you’re playing us for fools or what … ” She seems a bit stressed out and keeps pushing her hair back off her brow. “Anyway. Here’s my CV. You know how many ideas I’ve had for this company, but if we all have to keeping jumping through even more bloody hoops, then … whatever, Sam. Your call.”

“Elena—” Sam breaks off in bafflement.

“Just read my personal statement. It’s all in there.” She stalks off.

There’s a silent beat, then Sam wheels round, his face so ominous I feel a quailing inside.

“Start from the beginning. What did you do?”

“I sent an email.” I scuff my foot, feeling like a naughty child. “From you.”
