“You think so,” Sadie says scoffingly.

“Yes! You couldn’t make him say anything he didn’t genuinely believe on some level.”

“You think?” Sadie’s head jerks up, and her eyes glitter at me for a moment. “Very well. Challenge accepted.” She zooms toward the door.

“What challenge?” I say in horror. “I didn’t challenge you!”

I hurry back into the restaurant-but Sadie streaks ahead of me. I can see her yelling in Josh’s ear. I can see his eyes glazing over. I can’t get to the table because I’m stuck behind a waiter with about five plates. What the hell is she doing to him?

All of a sudden Sadie appears beside me again. Her lips are pressed together as though she’s trying not to laugh.

“What have you done?” I snap.

“You’ll see. And then you’ll believe me.” She looks so gleeful, I feel like throttling her.

“Leave me alone!” I mutter. “Just go away!”

“Very well!” she says, with an insouciant toss of her chin. “I’ll go! But you’ll still see I’m right!”

She vanishes and I approach the table nervously. Josh looks up with that faraway, punch-drunk expression, and my heart sinks. Sadie obviously got through to him, big-time. What’s she been saying?

“So!” I begin brightly. “Have you decided what to eat yet?”

Josh doesn’t even seem to hear. It’s as though he’s in a trance.

“Josh!” I snap my fingers. “Josh, wake up!”

“Sorry. I was miles away. Lara, I’ve been thinking.” He leans forward and gazes at me with great intensity. “I think I should become an inventor.”

“An inventor?” I gape at him.

“And I should move to Switzerland.” Josh is nodding seriously. “It’s just come to me, out of nowhere. This amazing… insight. I have to change my life. At once.”

I will murder her.

“Josh…” I try to keep calm. “You don’t want to move to Switzerland. You don’t want to be an inventor. You work in advertising.”

“No, no.” His eyes are shining as if he’s a pilgrim who’s seen the Blessed Virgin. “You don’t understand. I’ve been on the wrong path. It’s all falling into place. I want to go to Geneva and retrain in astrophysics.”

“You’re not a scientist!” My voice is shrill. “How can you be an astrophysicist?”

“But maybe I was meant to study science,” he says fervently. “Didn’t you ever hear a voice inside your head, telling you to change your life? Telling you that you’re on the wrong path?”

“Yes, but you don’t listen to the voice!” I lose all semblance of composure. “You ignore the voice! You say, ‘That’s a stupid voice!’”

“How can you say that?” Josh looks taken aback. “Lara, you have to listen to yourself. You’re the one who always told me that.”

“But I didn’t mean-”

“I was just sitting here, minding my own business, when the inspiration came to me.” He’s overflowing with enthusiasm. “Like an epiphany. Like a realization. Like when I realized I should be back with you. It’s exactly the same.”

His words are like a splinter of ice in my heart. For a few moments I can’t bring myself to speak.

“Is it… exactly the same?” I say at last.

“Well, of course.” Josh peers at me uncomprehendingly. “Lara, don’t get upset.” He reaches across the table. “Come with me to Geneva. We’ll start a new life. And do you want to know the other idea I’ve just had, out of the blue?” His face glows with happiness as he draws breath. “I want to open a zoo. What do you think?”

I want to cry. I think I might cry.

“Josh-”

“No, hear me out.” He slaps a hand on the table. “We start an animal charity. Endangered species. We hire experts, get some funding…”

Tears are welling up in my eyes as he talks. OK , I’m saying savagely to Sadie in my mind. I get it. I GET it .

“Josh.” I cut him right off. “Why did you want to get back together with me?”

There’s silence. Josh still has that trancey look in his eyes.

“I don’t remember.” His brow creases in a frown. “Something just told me it was the right thing to do. This voice in my head. It told me I still loved you.”

“But after you heard the voice.” I try not to sound too desperate. “Did it seem like all your old feelings for me were kicking in? Like an old car after you turn the handle round and round and it’s sputtering and then suddenly the engine comes to life. Did anything come to life?”
