Again, she remembered herself at that age, her stammering horror at being left alone in male company, her determination to stay single, for quite different reasons. And then she looked at Sanjay, who, she suspected, might not be as understanding of the situation as her granddaughter believed.

‘You know this place?’ Mr Vaghela had started to chew another piece of betel. His teeth were stained red.

She shook her head. With the air-conditioning turned off, she could already feel the elevating temperatures. Her mouth was dry, and she swallowed awkwardly. She had told Jennifer several times that she didn’t like cola.

‘Alang. Biggest shipbreaker’s yard in the world.’

‘Oh.’ She tried to look interested, but felt increasingly weary and keen to move on. The Bombay hotel, some unknown distance ahead, seemed like an oasis. She looked at her watch: how could anyone spend nearly twenty minutes purchasing two bottles of drink?

‘Four hundred shipyards here. And men who can strip a tanker down to nuts and bolts in a matter of months.’

‘Oh.’

‘No workers’ rights here, you know. One dollar a day, they are paid, to risk life and limb.’

‘Really?’

‘Some of the biggest ships in the world have ended up here. You would not believe the things that the owners leave on cruise ships – dinner services, Irish linen, whole orchestras of musical instruments.’ He sighed. ‘Sometimes it makes you feel quite sad, yaar. Such beautiful ships, to become so much scrap metal.’

The old woman tore her gaze from the shop doorway, trying to maintain a semblance of interest. The young could be so inconsiderate. She closed her eyes, conscious that exhaustion and thirst were poisoning her normally equable mood.

‘They say on the road to Bhavnagar one can buy anything – chairs, telephones, musical instruments. Anything that can come out of the ship they sell. My brother-in-law works for one of the big shipbreakers in Bhavnagar, yaar. He has furnished his entire house with ship’s goods. It looks like a palace, you know?’ He picked at his teeth. ‘Anything they can remove. Hmph. It would not surprise me if they sold the crew too.’

‘Mr Vaghela.’

‘Yes, madam?’

‘Is that a tea-house?’

Mr Vaghela, diverted from his monologue, followed her pointing finger to a quiet shopfront, where several chairs and tables stood haphazardly on the dusty roadside. ‘It is.’

‘Then would you be so kind as to take me and order me a cup of tea? I really do not think I can spend another moment waiting for my granddaughter.’

‘I would be delighted, madam.’ He climbed out of the car, and held open the door for her. ‘These young people, yaar, no sense of respect.’ He offered his arm, and she leant on it as she emerged, blinking, into the midday sun. ‘I have heard it is very different in Denmark.’

The young people came out as she was drinking her cup of what Mr Vaghela called ‘service tea’. The cup was scratched, as if from years of use, but it looked clean, and the man who had looked after them had made a prodigious show of serving it. She had answered the obligatory questions about her travels, through Mr Vaghela, confirmed that she was not acquainted with the owner’s cousin in Milton Keynes, and then, having paid for Mr Vaghela’s glass of chai (and a sticky pistachio sweetmeat, to keep his strength up, you understand), she had sat under the canopy and gazed out at what she now knew, from her slightly elevated vantage-point, to lie behind the steel wall: the endless, shimmering blue sea.

A short distance away, a small Hindu temple was shaded by a neem tree. It was flanked by a series of shacks that had apparently evolved to meet the workers’ needs: a barber’s stall, a cigarette vendor, a man selling fruit and eggs, and another with bicycle parts. It was some minutes before she grasped that she was the only woman in sight.

‘We wondered where you’d gone.’

‘Not for long, I assume. Mr Vaghela and I were only a few yards away.’ Her tone was sharper than she’d intended.

‘I said I didn’t think we should stop here,’ said Sanjay, eyeing first the group of men nearby, then the car with barely hidden irritation.

‘I had to get out,’ she said firmly. ‘Mr Vaghela was kind enough to accommodate me.’ She sipped her tea, which was surprisingly good. ‘I needed a break.’

‘Of course. I just meant – I would have liked to find somewhere more picturesque for you, it being the last day of your holiday.’

‘This will do me fine.’ She felt a little better now: the heat was tempered by the faintest of sea breezes. The sight of the azure water was soothing after the blurred and endless miles of road. In the distance, she could hear the muffled clang of metal against metal, the whine of a cutting instrument.

‘Wow! Look at all those ships!’

Jennifer was gesticulating at the beach, where her grandmother could just make out the hulls of huge vessels, beached like whales upon the sand. She half closed her eyes, wishing she had brought her glasses out of the car. ‘Is that the shipbreaking yard you mentioned?’ she said to Mr Vaghela.

‘Four hundred of them, madam. All the way along ten kilometres of beach.’

‘Looks like an elephant’s graveyard,’ said Jennifer, and added portentously, ‘Where ships come to die. Shall I fetch your glasses, Gran?’ She was helpful, conciliatory, as if to make amends for her prolonged stay in the shop.

‘That would be very kind.’

In other circumstances, she thought afterwards, the endless sandy beach might have graced a travel brochure, its blue skies meeting the horizon in a silvered arc, behind her a row of distant blue mountains. But with the benefit of her glasses, she could see that the sand was grey with years of rust and oil, and the acres of beachfront punctuated by the vast ships that sat at quarter-mile intervals and huge unidentifiable pieces of metal, the dismantled innards of the defunct vessels.

At the water’s edge, a few hundred yards away, a group of men squatted in a row on their haunches, dressed in faded robes of blue, grey and white, watching as a ship’s deckhouse swung out from a still-white hull anchored several hundred feet from the shore and crashed heavily into the sea.

‘Not your usual tourist attraction,’ said Sanjay.

Jennifer was staring at something, her hand lifted to shield her eyes against the sun. Her grandmother gazed at her bare shoulders and wondered if she should suggest the girl cover up.

‘This is the kind of thing I was talking about. Come on, Jay, let’s go and have a look.’

‘No, no, miss. I don’t think this is a good idea.’ Mr Vaghela finished his chai. ‘The shipyard is no place for a lady. And you would be required to seek permission from the port office.’

‘I only want a look, Ram. I’m not going to start wielding a welder’s torch.’

‘I think you should listen to Mr Vaghela, dear.’ She lowered her cup, conscious that even their presence at the tea-house was attracting attention. ‘It’s a working area.’

‘And it’s the weekend. There’s hardly anything going on. Come on, Jay. No one’s going to mind if we go in for five minutes.’

‘There’s a guard on the gate,’ said Sanjay.

She could tell that Sanjay’s natural disinclination to venture further was tempered by his need to be seen as a fellow-adventurer, a protector, even. ‘Jennifer dear—’ she said, wanting to spare his embarrassment.

‘Five minutes.’ Jennifer jumped up, almost bouncing with impatience. Then she was half-way across the road.

‘I’d better go with her,’ said Sanjay, a hint of resignation in his voice. ‘I’ll get her to stay where you can see her.’

‘Young people,’ said Mr Vaghela, chewing meditatively. ‘There is no telling them.’

A huge truck trundled past, the back filled with twisted pieces of metal to which six or seven men clung precariously.

After it had passed, she could just make out Jennifer in conversation with the man on the gate. The girl smiled, ran her hand through her blonde hair. Then she reached into her bag and handed him a bottle of cola. As Sanjay caught up with her, the gate opened. And then they were gone, reappearing several seconds later as tiny figures on the beach.

It was almost twenty minutes before either she or Mr Vaghela could bear to say what they both thought: that the young people were now not just out of sight but way over time. And that they would have to go and look for them.

Revived by her tea, she struggled to suppress her irritation that her granddaughter had again behaved in such a selfish, reckless manner. Yet she knew that her response was due partly to fear that something would happen to the girl while she was in her charge. That she, helpless and old, in this strange, otherworldly place, would be responsible in circumstances she could not hope to control.

‘She won’t wear a watch, you know.’

‘I think we should go and bring them back,’ said Mr Vaghela. ‘They have obviously forgotten the time.’

She let him pull back her chair and took his arm gratefully. His shirt had the soft papery feel of linen washed many, many times.

He pulled out the black umbrella that he had used on several occasions and opened it, holding it so that she could walk in the shade. She stayed close to him, conscious of the stares of the thin men behind, of those who passed by on whining buses.

They halted at the gate, and Mr Vaghela said something to the security guard, pointing through at the shipyard beyond. His tone was aggressive, belligerent, as if the man had committed some crime in allowing the young people to go through.

The guard said something apparently conciliatory in reply, then shepherded them in.

The ships were not intact, as she had first believed, but prehistoric, rusting hulks. Tiny men swarmed over them like ants, apparently oblivious to the shriek of rent metal, the high-pitched squeal of steel cutters. They held welding torches, hammers, spanners, the beating chimes of their destruction echoing disconsolately in the open space.

Those hulls still in deeper water were strung with ropes from which dangled impossibly frail platforms on which metal moved to the shore. Closer to the water, she lifted her hand to her face, conscious of the pervasive stench of raw sewage, and something chemical she could not identify. Several yards away a series of bonfires sent toxic plumes of thick smoke into the clear air.

‘Please be careful where you walk,’ said Mr Vaghela, gesturing towards the discoloured sand. ‘I do not think this is a good place.’ He glanced back, apparently wondering whether the old woman should remain at the tea-house.

But she did not want to sit and face those young men alone. ‘I shall hold on to you, Mr Vaghela, if you don’t mind.’

‘I think this would be recommended,’ he said, squinting into the distance.

Around them, on the sand, stood chaotic piles of rusting girders, what looked like oversized turbines, and crumpled steel sheets. Huge barnacle-encrusted chains snaked around everything or were piled in seaweedy coils, like giant sleeping serpents, dwarfing the workers around them.

Jennifer was nowhere to be seen.

A small group of people had gathered on the sand, some clutching binoculars, others resting against bicycles, all looking out to sea. She took a firmer hold of Mr Vaghela’s arm and paused for a second, adjusting to the heat. Then they moved forward slowly down to the shore, to where men with walkie-talkies and dusty robes moved backwards and forwards, talking excitedly to each other, and children played unconcernedly at their parents’ feet.

‘Another ship is coming in,’ said Mr Vaghela, pointing.

They watched what might have been an old tanker, towed by several tugs, becoming gradually distinct as it drew towards the shore. A Japanese four-wheel drive roared past, screeching to a halt a few hundred yards ahead. And it was then that they became aware of voices raised in anger and, as they turned past a huge pile of gas cylinders, of a small crowd further along, standing in the shadow of a huge metallic hull. In their midst, there was some kind of commotion.
