His mother was standing alone in the middle of the kampung, distraught, looking around as if searching for something. When she spotted Prabir she started banging her fist on her forehead. She screamed at him angrily, ‘Take her away! She mustn’t see!’

Prabir stopped at the edge of the kampung, confused, fighting back tears. Where was his father?‘What happened? Ma?’

His mother stared at him as if he was an idiot. ‘Where’s the ladder?’ she wailed. ‘What did you do with the ladder?’

Prabir couldn’t remember. He’d meant to put it in the storage hut when they’d finished painting the roofs, but that would have been the first place she’d checked.

He stepped forward uncertainly. ‘I’ll help you look.’

His mother waved him away miserably, then started walking in circles around the middle of the kampung.

Madhusree was scarlet-faced, screaming and trying to slither out of his grip. Prabir ran over to his parents’ hut and placed her in her cot. She was tall enough now to climb over the sides if she wanted to, but smart enough to realise that the fall would do her serious harm. Prabir knelt down and pressed his face against the bars. ‘I’ll be back soon, I promise. With Ma. OK?’ He didn’t wait for an answer.

He found the ladder in the undergrowth behind the butterfly hut, the last place he’d used it. He picked it up one-handed and started running towards his mother; it wasn’t all that heavy, but it swayed sideways as he moved, throwing him off balance.

He called out nervously, ‘Where should I take it? Where’s Baba?’

She stared at him blankly for several seconds, then put her hand over her mouth and closed her eyes. Prabir stood watching her, his skin growing icy.

When she opened her eyes she seemed calmer.

She said softly, ‘Baba’s been hurt. I’m going to need your help. But you have to do exactly what I tell you.’

Prabir said, ‘I will.’

‘Wait there.’ She vanished into the storage hut, then emerged with two empty wooden packing crates. ‘Listen to me carefully. I want you to follow five metres behind me. Walk where I walk, nowhere else. Bring the ladder, but don’t let it touch the ground.’

As she spoke, Prabir heard doubt rising in her voice, as if she was beginning to think this was too much to ask of him. He said firmly, ‘Follow five metres behind you. Walk where you’ve walked. Don’t let the ladder touch the ground.’

She smiled reluctantly. ‘OK. I know you’re not stupid, I know you’ll be careful. Can you be brave for me, too?’ She searched his face, and Prabir felt his chest tightening.

‘Yes.’

His father was lying in a shallow crater in the middle of the garden behind the storage hut. His legs were mangled, almost shredded. Dark blood was spurting from his thighs, welling up through a layer of sand that must have rained down on top of him from the blast. His eyes were closed, his face set against the pain. Prabir was too shocked for tears, and when he felt a plaintive cry of ‘Baba!’ rising in his throat, he silenced it.

His mother spoke almost in a whisper. ‘I’m back, love. It won’t be much longer.’ His father showed no sign of having heard her.

She turned to Prabir. ‘There could be more mines buried in the garden. So we’ll put the ladder between the crates, like a bridge. Then I’ll walk across to Baba and bring him back. Do you understand?’

Prabir said, ‘I can do it. I’m lighter.’ The ladder was aluminium, and he was afraid that it might not take the weight of two adults.

His mother shook her head impatiently. ‘You couldn’t lift him, darling. You know that. Just help me get the ladder in position.’

She placed one of the crates squarely on the ground at the edge of the garden, at the point nearest his father. Then she walked a couple of metres away, and motioned to Prabir to approach the crate. When he was standing beside it, he swung the ladder towards her, and she took hold of the end. She was still carrying the second crate in her left hand, gripping it by one exposed side.

As his mother walked around the edge of the garden, Prabir fed her more of the ladder, until he was holding it by the opposite end. She smiled at him encouragingly, but he felt his heart pounding with fear for her. Staying out of the garden was no guarantee of safety. The rectangle of cleared soil must have looked like an ideal target from the air—and maybe it was easier for a self-laying mine to penetrate the ground and cover its tracks where there was no vegetation—but there could still be others, buried anywhere at all.

As his mother approached the far corner, they both had to stretch their arms to keep their hold on the ladder, and it was soon clear that even this wouldn’t be enough. She seemed to be about to cut across the garden, but Prabir shouted out to her, ‘No! I can move closer to you!’ He gestured towards the corner nearest to him, where she’d already proved the ground safe. ‘I’ll stand over there. Then once you’ve turned the corner I can walk back towards the crate, keeping step with you.’

His mother shook her head angrily, but she was cursing herself for not thinking clearly. ‘You’re right. We’ll do it that way.’

Once they were holding the ladder across the full width of the garden, carrying it straight towards his father, Prabir began to feel hopeful. Just a few more steps and his mother would have no untried ground left to walk. He kept his eyes averted from his father’s legs, but a cool voice in his head was already daring to counsel optimism. People had survived these kinds of injuries, in remote villages in Cambodia and Afghanistan. His mother had studied human anatomy and performed surgery on experimental animals; that had to be of some use.

Prabir waited for her to put the second crate on the ground, then they lowered the ladder into place together. He didn’t doubt that the crates would take the load; there were a dozen of them scattered around the kampung, and he’d seen his father standing on them to reach things. If the ladder didn’t buckle, the one remaining problem was the far end sliding off the crate.

His mother followed his gaze.

She said, ‘You watch that, and tell me if it moves. If I shift it one way by accident, I can always shift it back.’

She took off her shoes and climbed on to the crate. The ladder’s steps were sloped so as to be horizontal when the ladder was a few degrees off vertical; the sides they presented now were curved metal, with none of the non-slip rubber that covered the tops. But as Prabir looked on, his mother found a way to balance with her feet resting on both the supporting rails and the sides of the steps. Still above the crate, she screwed her eyes shut and began swaying slightly, her arms partly raised at her sides—rehearsing the moves that would restore her equilibrium without compromising her footing, so she wouldn’t have to guess them when she was halfway across. Prabir’s throat tightened, his fear for her giving way to love and admiration. If there was anyone in the world who could do this, it was her.

She opened her eyes and started walking along the ladder.

Prabir kept his hands on his end of the ladder, pushing it down firmly against the top of the crate, and fixed his gaze on the other, unattended crate. He could feel a slight vibration with each step his mother took, but the ladder wasn’t trying to jerk sideways out of his grip. He risked a quick glance at his mother’s face; she was staring sightlessly over his head. He looked down at the opposite crate again. A wooden plank might have bowed enough to push the crates apart, its curvature redirecting the load, but the ladder was far too rigid for that. It would take the weight of both of them, easily; he was sure of that now.

His mother paused. Prabir watched her feet as she took one more step forward on her left, turning her body partly sideways so she could face his father. She dropped slowly to a crouch, then reached down towards him. The ladder was about half a metre from the ground; she could just touch his face with her fingertips.
