or twice her head rocked a little on her shoulders. Finally she said, 'Krystal was s'posed to drop him and she never.'
'Krystal is your daughter, isn't she? How old is she?'
'Fourteen,' said Terri dreamily, ''n'a half.'
Kay could see from her notes that Krystal was sixteen. There was a long pause.
Two chipped mugs stood at the foot of Terri's armchair. The dirty liquid in one of them had a bloody look. Terri's arms were folded across her flat breast.
'I had him dressed,' said Terri, dragging the words from deep in her consciousness.
'Sorry, Terri, but I've got to ask,' said Kay. 'Have you used this morning?'
Terri passed a bird's claw hand over her mouth.
'Nah.'
'Wantashit,' said Robbie, and he scurried towards the door.
'Does he need help?' Kay asked, as Robbie vanished from sight, and they heard him scampering upstairs.
'Nah, 'e can doot alone,' slurred Terri. She propped her drooping head on her fist, her elbow on the armchair. Robbie let out a shout from the landing.
'Door! Door!'
They heard him thumping wood. Terri did not move.
'Shall I help him?' Kay suggested.
'Yeah,' said Terri.
Kay climbed the stairs and operated the stiff handle on the door for Robbie. The room smelled rank. The bath was grey, with successive brown tidemarks around it, and the toilet had not been flushed. Kay did this before allowing Robbie to scramble onto the seat. He screwed up his face and strained loudly, indifferent to her presence. There was a loud splash, and a noisome new note was added to the already putrid air. He got down and pulled up his bulging nappy without wiping; Kay made him come back, and tried to persuade him to do it for himself, but the action seemed quite foreign to him. In the end she did it for him. His bottom was sore: crusty, red and irritated. The nappy stank of ammonia. She tried to remove it, but he yelped, lashed out at her, then pulled away, scampering back down to the sitting room with his nappy sagging. Kay wanted to wash her hands, but there was no soap. Trying not to inhale, she closed the bathroom door behind her.
She glanced into the bedrooms before returning downstairs. The contents of all three spilt out onto the cluttered landing. They were all sleeping on mattresses. Robbie seemed to be sharing a room with his mother. A couple of toys lay among the dirty clothes strewn all over the floor: cheap, plastic and too young for him. To Kay's surprise, the duvet and pillows both had covers on them.
Back in the sitting room, Robbie was whining again, banging his fist against the stack of cardboard boxes. Terri was watching from beneath half-closed eyelids. Kay brushed off the seat of her chair before sitting back down.
'Terri, you're on the methadone programme at the Bellchapel Clinic, isn't that right?'
'Mm,' said Terri drowsily.
'And how's that going, Terri?'
Pen poised, Kay waited, pretending that the answer was not sitting in front of her.
'Are you still going to the clinic, Terri?'
'Las' week. Friday, I goes.'
Robbie pounded the boxes with his fists.
'Can you tell me how much methadone you're on?'
'Hundred and fifteen mils,' said Terri.
It did not surprise Kay that Terri could remember this, but not the age of her daughter.
'Mattie says here that your mother has been helping with Robbie and Krystal; is that still the case?'
Robbie flung his hard, compact little body against the pile of boxes, which swayed.
'Be careful, Robbie,' said Kay, and Terri said, 'Leave 'em,' with the closest thing to alertness Kay had heard in her dead voice.
Robbie returned to beating the boxes with his fists, for the pleasure, apparently, of listening to the hollow drumbeat.
'Terri, is your mother still helping to look after Robbie?'
'Not m'mother, gran.'
'Robbie's gran?'
'My gran, innit. She dun ... she ain't well.'
Kay glanced over at Robbie again, her pen at the ready. He was not underweight; she knew that from the feel and look of him, half-naked, as she had wiped his backside. His T-shirt was dirty, but his hair, when she had bent over him, had smelled surprisingly of shampoo. There were no bruises on his milk-white arms and legs, but there was the sodden, bagging nappy; he was three and a half.
'M'ungry,' he shouted, giving the box a final, futile whack. 'M'ungry.'
'You c'n'ave a biscuit,' slurred Terri, but not moving. Robbie's yells turned to noisy sobs and screams. Terri made no attempt to leave her chair. It was impossible to talk over the din.
'Shall I get him one?' shouted Kay.
'Yeah.'
Robbie ran past
