‘Oh well, that fills me with confidence,’ she said. ‘Promise you’ll be there whatever happens?’

‘I promise,’ I said and, following Walid’s instructions, started winding a strip of the sheet tightly around her head. She mumbled something, and I assured her that I’d cut a hole for her mouth when I’d finished. I secured the sheet the way one of my mum’s sisters had taught me to secure a headscarf.

‘Oh good,’ said Lesley once I’d cut the promised hole. ‘Now I’m the invisible woman.’ Just to be on the safe side, I knotted the material at the back of her neck to maintain the tension. I found a bottle of Evian by the chaise longue and used it to soak the makeshift bandage.

‘You’re trying to drown me now?’ asked Lesley.

‘Dr Walid told me to do this,’ I said. I didn’t tell her that it was to stop the bandage sticking to the wounds.

‘It’s cold,’ she said.

‘I’m sorry,’ I said. ‘I’m going to need Henry back.’

Henry Pyke returned with transparent eagerness. ‘What must I do now?’

I cleared my mind and opened my hand and spoke the word – ‘Lux!’ A werelight flowered above my hand. ‘This is the light that will take you to your place in history,’ I said. ‘Take my hand.’ He was reluctant. ‘Don’t worry, it won’t burn you.’

Lesley’s hand closed around mine, light leaking out between her fingers. I didn’t know how long my magic would last, or even if the whole blood-sucking business with Molly had left me much magic in the first place. Sometimes you just have to hope for the best.

‘Listen, Henry,’ I said. ‘This is your moment, your big exit. The lights will dim, your voice will fade, but the last thing the audience will see is Lesley’s face. Hold on to the image of her face.’

‘I don’t want to go,’ said Henry Pyke.

‘You must,’ I said. ‘That’s the mark of true greatness in an actor – knowing, down to the precise moment, when to make his exit.’

‘How wise of you, Peter,’ said Henry Pyke. ‘That is the true mark of genius, to give oneself to one’s public but to retain that private side, that secret space, that unknowable …’

‘To leave them wanting more,’ I said, trying to keep the desperation out of my voice.

‘Yes,’ said Henry Pyke, ‘to leave them wanting more.’

And then the mouthy git was gone, right on cue.

I heard heavy footsteps on the iron staircase. Dr Walid and the cavalry had arrived. Red stains immediately bloomed on the white sheets covering Lesley face. I heard her gurgling and choking as she tried to breathe. A big hand landed on my shoulder and unceremoniously pushed me out of the way.

I let myself fall to the floor – I figured I could catch up on some sleep now.
