But what—

I mean, what on earth—

Lois Kellerton shoplifted three pairs of socks? Is this some kind of candid-camera show?

For what seems like the longest moment, we’re both motionless, staring at each other. I’m remembering her as Tess in that brilliant adaptation of Tess of the d’Urbervilles. God, she made me cry. And there was that sci-fi one where she got deliberately stranded on Mars at the end, in order to save her half-alien children. I cried buckets, and so did Suze.

I clear my throat, trying to gather my thoughts. ‘I … I know who you—’

‘Please,’ she cuts me off in that familiar husky voice. ‘Please.’ She takes off her dark glasses and I stare at her in fresh shock. She looks terrible. Her eyes are red-rimmed and her skin is all flaky. ‘Please,’ she says a third time. ‘I’m … I’m so sorry. I’m so sorry. Are you employed by the shop?’

‘No. I’m a customer. I was up a ladder.’

‘Did they see me?’

‘I don’t know. I don’t think so.’

With a trembling hand she grabs the three pairs of socks from her bag and offers them to me.

‘I don’t know what I was doing. I haven’t slept for two nights. I think I went a little crazy. I never did anything like this before. I never will again. Please,’ she whispers again, shrinking inside her hoody. ‘Take the socks. Take them back.’

‘Me?’

‘Please.’ She sounds desperate. At last, awkwardly, I take the socks from her.

‘Here.’ She’s scrabbling in her bag again and produces a fifty-dollar note. ‘Give this to the employees.’

‘You look quite … um … stressed,’ I venture. ‘Are you OK?’

Lois Kellerton raises her head and meets my eyes, and I’m suddenly reminded of a leopard I once saw in a Spanish zoo. That looked desperate, too.

‘Are you going to tell the police?’ she breathes, so quietly I can barely hear her. ‘Are you going to tell anyone?’

Oh God. Oh God. What do I do?

I put the socks in my bag, playing for time. I should tell the police. Of course I should. What difference does it make if she’s a movie star? She stole the socks and that’s a crime and I should perform a citizen’s arrest right now and march her off for justice.

But … I can’t. I just can’t. She looks so fragile. Like a moth or a paper flower. And after all, she’s giving the socks back, and she’s making a donation, and it sounds like she just had a moment of madness …

Lois Kellerton’s head is bowed. Her face is hidden inside the grey hood. She looks as though she’s waiting for an execution.

‘I won’t tell anyone,’ I say at last. ‘I promise. I’ll give the socks back and I won’t tell anyone.’

As I release my grip on her, her thin hand squeezes mine. Her dark glasses are already back on her face. She looks like an anonymous skinny girl in a hoody.
