Clara could only stare back at her, too surprised to respond. ‘I’m sorry?’

‘Where’s Luke?’

She’d had no idea the woman even knew their names. Perhaps she’d seen them written on their post, but it was the way she said it – so familiar, so knowing, and with such a strange smile on her lips. ‘What do you mean?’ Clara asked but the woman only turned and carried on up the stairs. ‘Excuse me! Why are you asking about Luke?’ but there was still no reply. Clara stood staring after her. It was as if the world was conspiring in some surreal joke against her. The door to the upstairs flat opened and then closed again and at last Clara went back to her own flat. She stood in her narrow hallway, listening, until a few seconds later the familiar thud of bass began to thump against her ceiling once more.

It was past two. She should go back to work; her colleagues would be worried by now. But Clara didn’t move. Should she start phoning around hospitals? Perhaps she should google their numbers – at least that way she would be doing something. She went to the small box room they used as an office and at a touch of the mouse pad Luke’s laptop flickered into life, the browser opening immediately at Google Mail – and Luke’s personal email account.

For a second she stared at the screen, her finger hovering, knowing she shouldn’t pry. But then her gaze fell upon his list of folders. Below the usual ‘Inbox’ ‘Drafts’ and ‘Trash’ was one labelled, simply, ‘Bitch’. She stared at it in shock before clicking on it. And then her jaw dropped – there were at least five hundred messages, sent from several different accounts over the past year, sometimes as often as five times a day. She opened and read them one by one.

Did you see me today, Luke? I saw you. Keep your eyes peeled.

And,

I know you, Luke, I know what you are, what you’ve done. You might have most people fooled, but you don’t fool me. Men like you never fool me.

How are your parents, Luke? How are Oliver and Rose? Do they know the truth about you – your family, your friends, your colleagues? How about that little girlfriend of yours, or is she too stupid to see? She looks really fucking stupid, but she’ll find out soon enough.

And,

Women are nothing to you, are we, Luke? We’re just here for your convenience, to fuck, to step over, to use or to bully. We’re disposable. You think you’re untouchable, you think you’ve got away with it. Think again, Luke.

Then,

What will they say about you at your funeral, Luke? Say your goodbyes, it’s going to be soon.

The very last one had been sent only a few days before.
