“He’s in there already!” She suddenly appears, looking even more hyper than before. “He’s absolutely swoonsome.”

My heart sinks. I was hoping he might have stood me up.

“How do I look?” Sadie’s smoothing her hair down, and I feel a sudden pang of compassion for her. It can’t be much fun, going on a date and being invisible.

“You look great,” I say reassuringly. “If he could see you, he’d think you were really hot.”

“Hot?” She looks confused.

“Sexy. Pretty. You’re a hottie. It’s what we say.”

“Oh, good!” Her eyes travel nervously to the door and back. “Now, before we go in, remember this is my date.”

“I know it’s your date,” I say patiently. “You’ve drummed it into me enough times-”

“What I mean is-be me.” She fixes me with an urgent look. “Say whatever I tell you to say. Do whatever I tell you to do. Then I’ll feel as though it’s really me talking to him. Do you understand?”

“Don’t worry! I get it. You feed me the lines and I’ll say them. I promise.”

“Go on, then!” She gestures at the entrance.

I push through the heavy frosted glass doors and find myself in a chic lobby with suede-paneled walls and low-level lighting. There’s another set of double doors ahead, beyond which I can see the bar. As I pass through, I catch a glimpse of myself in a tinted mirror and feel a clench of dismay.

Somehow I feel a million times more ludicrous here than I did in my flat. My necklaces are jangling with every step. My feather is bobbing around in my headdress. I look like a twenties-o-gram. And I’m standing in a minimalist bar full of cool people in understated Helmut Lang.

As I’m edging forward, all prickly with self-consciousness, I suddenly spot Ed. He’s sitting about ten yards away, in a conventional trousers-and-jacket combo, drinking what looks like a conventional gin and tonic. He looks up, glances my way, then does a double take.

“You see?” says Sadie triumphantly. “He’s transfixed by the sight of you!”

He’s transfixed, all right. His jaw has fallen and his face has turned a pale green color.

Very slowly, as though forcing himself through noxious mud, he gets to his feet and approaches me. I can see the bar staff nudging one another as I walk through the bar, and from a nearby table comes a sudden gasp of hilarity.

“Smile at him!” Sadie is insisting loudly in my ear. “Walk toward him with a shimmy and say, ‘Hello, Daddy-O!’”

Daddy-O?

It’s not my date, I remind myself feverishly. It’s Sadie’s. I’m only acting a part.

“Hello, Daddy-O!” I say brightly as he draws near.

“Hi,” he says faintly. “You look…” He moves his hands helplessly.

All around, the buzz of conversation has died to a halt. The whole bar is watching us. Great.

“Say some more!” Sadie is hopping around in excitement, clearly oblivious to the awkwardness. “Say, ‘You look pretty dapper yourself, you old thing.’ And twirl your necklace.”

“You look pretty dapper yourself, you old thing!” I fix him with a rictus smile, swinging my beads around so hard that one of the necklaces catches me in the eye.

Ow. That hurt.

“OK.” Ed seems barely able to talk for embarrassment. “Well. Can I… get you a drink? A glass of champagne?”

“Ask for a swizzle stick!” instructs Sadie. “And smile! You haven’t laughed once!”

“Could I have a swizzle stick?” I give a high-pitched giggle. “I simply adore swizzle sticks!”

“A swizzle stick?” Ed frowns. “Why?”

Fuck knows why. I dart a helpless look at Sadie.

“Say, ‘To stir the bubbles out, darling!’” she hisses.

“To stir the bubbles out, darling!” I giggle brightly again, and twirl my necklaces for good measure.

Ed looks like he wants to sink into the floor. I don’t blame him.

“Why don’t you take a seat?” he says in a strained voice. “I’ll bring over the drinks.”

I head over to the table where he was sitting and pull up a suede upholstered chair.

“Sit like this,” commands Sadie, adopting an affected pose with her hands on her knee, and I copy as best I can. “Open your eyes wider!” She looks restlessly around at all the clusters of people sitting in groups and standing at the bar. The hum of chatter has resumed, and there’s a low throbbing of lounge-style music. “When does the band arrive? When will the dancing start?”
