When I see the empty bed, I am sick all over the floor. I hear someone screaming like a siren. That someone is me. Question Mark appears, sits me down and helps me clean myself up.

‘Your nana has been moved to a room of her own,’ he says. ‘Don’t you remember? We told you yesterday.’

I don’t remember.

‘Is she going to die soon?’ I ask.

‘She’s very weak now, Mira,’ he says, walking me to Nana’s new room. Question Mark’s hand is smooth and cool, like powdered silk. The moment my hand’s in his, I start to feel calm.

NO ENTRY reads the sign on Nana’s door. Question Mark says that Nana Josie doesn’t want any other visitors, only ‘immediate family’. I ask what ‘immediate family’ means. Dad says it means ‘only us’.

I open the door, but somehow it still feels like I shouldn’t go in, so I stand in the doorway watching Nana. Her Dying Room has a view on to those enormous Hampstead houses that look like the ones in Mary Poppins that rise up and up ‘to the highest heights’.

Right outside the Dying Room there are two huge oak trees just coming into flower. The window takes up one whole side of the room. The sun streams in and shines on Nana’s face, warming her blankets. Dad asks if he should close the blinds, but Nana smiles ‘no’ with her mouth. She’s enjoying sunbathing.

Nana talks silently now as much as she can. I think she’s saving her energy for dying. I sit next to her. I don’t dare lie on the bed any more, because she’s so thin I might squash her. I gaze out of the window and across the street. I can see straight into what looks like an artist’s studio. There are two enormous windows on either side of the room so that, through the far window, I glimpse the green of the Heath stretching out into the distance.

‘They must have a great view of London,’ I say.

‘Perfect,’ Nana whispers. Her voice is dry and scratchy. ‘I’d like to see that room.’

‘Just imagine, Nana, if I open this window, and they open theirs, you could fly out of here across the street, into that room and then straight out the other side.’

Nana is squeezing my hand. ‘How’s someone someone?’ she whispers, smiling.

There doesn’t seem much point denying it now.

‘He’s fine,’ I whisper, smiling back.

Then suddenly Nana starts to cough. I think I’ve been making her talk too much. Doris comes in and props her up on her pillows. Nana calls Doris ‘the poet’ because of the way she sings when she talks, so you almost forget the meaning of the words; you can just taste something sweet in your mouth.

Doris sits in the sunshine on Nana’s bed. She takes a little white bag from the trolley. Inside it is a soft stick, like a toothbrush the size of a cotton bud, which she smoothes around Nana’s teeth. Afterwards, she takes out a tiny sponge, which she dips into drinking water and squeezes into Nana’s mouth. Doris’s hands are small and shiny like they’ve been rubbed in oil. I think it’s a shame that she has to slide her beautiful hands into those chalky white gloves. Doris dips the sponge in water again and touches it against Nana’s lips, so gently, dab, dab, dab. I do not think I have ever seen anyone do anything with more love than Doris performs Nana’s tooth-brushing ceremony.

Nana sighs and closes her eyes. Question Mark walks silently in and asks Nana if she’s comfortable. She nods twice with her eyes closed. Everything seems to have slowed down here in the Dying Room. There is nothing on Nana’s bedside table. No art books, no paintings, no fruit, no water . . . no water.

I try to hold Nana’s hand, but her fingers are all curled up.

Krish brings Nana his Aboriginal picture. My has mounted it on a board, so it looks even better. He doesn’t say anything, but he holds it up for her to see. She just stares at it, lost in the millions of colours swirling around and around. Then she looks at Krish and mouths ‘thank you’ and Krish bows his head on to Nana’s knee. After a while he is very still and his breathing is quiet. He has fallen asleep. She lifts her hand and places it on his head; just the effort of that movement makes her breathless. I tell Nana that Krish spent all night finishing this picture. She gestures for me to prop it up on her bedside table. As I leave the room, Nana is lost somewhere among the billions of coloured dots.

On the way out, we drop into the Family Room. Mum’s talking to Jay, who’s brought a fruit salad for Nana. When Jay opens the fridge door and sees that Nana’s shelf is full of little plastic boxes of food that haven’t been touched, she puts the fruit salad back in her bag and empties Nana’s shelf. Tears roll down her cheeks as she wipes the shelf clean.

In the hospice people talk with their eyes, with a quiet hand on your arm, or a nod. You have to really look to see what’s going on. Twice today, I have seen Dr Clem and Doris in silent conversation with my dad and Aunty Abi. They have these conversations where no words escape when they pass each other in the corridor. After one of these silent conversations my dad walks off to the Family Room with his head and eyes lowered.
