The girl was deep in conversation with another skinny someone – a someone I recognised with a painful thud. Serena. I prepared myself to say hello, but she just gazed at me vacantly, immaculate in a long leather coat, then tightened the belt around her tiny waist and carried on her conversation. I thought I heard her mention a wedding as I slunk back into the changing-room, sinking down on the stool in the corner.

When I eventually came out again, Serena was admiring her many reflections, all clad in a pair of vertiginous snakeskin boots. How appropriate and how very unethical, I thought sourly.

I bought the dress just to prove I had as much panache as them, and then I let the door bang behind me as I strode purposefully out of the shop. Outside, the street was busy, the clamour of Covent Garden loud and vibrant – but I felt like I’d lost my mooring, like I was floating off to sea.

Somehow it took some time to get back to work.

In a show of power no doubt born from my afternoon flit, Charlie had ensured I had a stack of new stuff on my desk to sort out for Monday’s programme. I was just putting the phone down from briefing Renee when he wandered in, breathing brandy fumes at me.

‘Marvellous lunch with Alan Yentob,’ Charlie crowed, pulling a book on the Lost Gardens of Heligan from my shelf. ‘He’s wetting himself with excitement over my idea for a layman’s Panorama. Current affairs for the thicko.’

‘Really?’ I said politely. It was extremely hard to imagine Yentob in Charlie’s thrall.

‘Yes, darling.’ He perched on the edge of my desk. ‘The Easy View, I think we’ll call it. You know, I never see you as the country type.’ He flicked through the garden book indolently. ‘Cornwall’s deeply unfashionable these days, darling. So bloody far away, and always raining. Give me Dubai any time.’ Charlie shoved the book back, knocking three box-files off the other end that he didn’t bother to retrieve. ‘Going to Bel’s tonight?’

‘Um, I’m thinking about it.’ I doodled on my pad, holding my breath. ‘Are you?’

‘Wouldn’t miss it for the world, darling.’

I breathed out.

‘So sad to be losing one of our very best girls.’ Bel had long since progressed onto make-up for drama and film, but Charlie liked to think of himself as a great benefactor, responsible for everyone’s career, and Bel was always remembered fondly. ‘Don’t be late now, eh?’ He strolled off around the office to peer down some cleavages.

I was so long at my desk that all the other girls left; they’d wait for me in the bar downstairs, they said, wired with Friday night anticipation. Eventually I headed to the loo with my dress. Mid tights-change, my mobile rang. ‘Private number’ flashed up on the display.

‘Hello?’

Nothing.
