The spectacle briefly deprived Mr Doughty of his breath: 'I say,' he muttered at last, wiping his forehead, which was already streaming in anticipation of the feast, 'now here's a sight for Chinnery's paintbrush!'

'Exactly, sir,' said Paulette, although she had not quite heard what he had said – for her attention, if not her gaze, was focused upon the place to her left, where Zachary had now appeared. Yet she dared not turn away from the pilot, for she had more than once been reprimanded by Mrs Burnham for the solecism of speaking with a left-hand neighbour out of turn.

Mr Doughty was still exclaiming over the fare when Mr Burnham cleared his throat in preparation for the saying of grace: 'We thank you Lord…' In emulation of the others, Paulette held her clasped hands to her chin and shut her eyes – but she couldn't resist stealing a surreptitious glance at her neighbour, and was greatly discomposed when her eyes encountered Zachary's, who was also peering sideways, over his fingertips. They both flushed and looked hurriedly away, and were just in time to echo Mr Burnham's sonorous 'Amen'.

Mr Doughty wasted no time in spearing an ortalan. 'Tantivy, Miss Lambert!' he whispered to Paulette, as he dropped the bird on her plate. 'Take it from an old hand: have to be jildee with the ortolans. They're always the first to go.'

'Why thank you.' Paulette's words were lost on the pilot, whose attention was now focused on the dumbpoke. With her senior dinner-partner thus distracted, Paulette was free at last to turn to Zachary.

'I am glad, Mr Reid,' she said formally, 'that you could spare an evening for us.'

'Not as glad as I am, Miss Lambert,' said Zachary. 'It's not often that I'm invited to such a feast.'

'But Mr Reid,' said Paulette, 'my little finger has told me that you have been sortieing a great deal of late!'

'Sort… sortieing?' said Zachary in surprise. 'And what might you mean by that, Miss Lambert?'

'Forgive me,' she said. 'I mean dining out – you have been doing so a great deal, no, of late?'

'Mr Doughty and his wife have been very kind,' said Zachary. 'They've taken me with them to a few places.'

'You are lucky,' said Paulette, with a conspiratorial smile. 'I believe your colleague, Mr Crowle, is not so fortunate?'

'Wouldn't know about that, Miss.'

Paulette lowered her voice: 'You know, you must be careful with Mr Crowle. Mrs Burnham says he is an awful thug.'

Zachary stiffened. 'I'm not a'feared of Mr Crowle.'

'But have a care, Mr Reid: Mrs Burnham says she will not have him in the house. You must not tell him you were here tonight.'

'Don't worry, Miss,' said Zachary smiling. 'Mr Crowle's not a man I'm likely to be sharing confidences with.'

'Is he not on the ship then?'

'No,' said Zachary. 'None of us are. The Ibis is in dry dock and we're all liberty-men in the meantime. I've moved into a boarding house.'

'Really? Where?'

'In Kidderpore – Watsongunge Lane. Jodu found it for me.'

'Oh?' Paulette glanced over her shoulder to make sure that no one else had heard Jodu's name, and turned back to Zachary reassured.

Recently, Mr Burnham had installed a new fixture to cool the dining room. Known as a Thermantidote, the device was a winnowing machine that had been fitted with a propeller and a thick mat of fragrant khus-khus. The men who had once pulled the ropes of the overhead punkahs were now employed in operating the Thermantidote: while one wetted the machine's rush screen the other turned the propeller by means of a handle, forcing a constant stream of air through the dampened mat. Thus, by means of evaporation, the machine was supposed to create a wonderfully cooling breeze. Such at least was the theory – but in rainy weather the Thermantidote added greatly to the humidity, making everyone sweat even more than usual, and it also produced a loud, grinding noise that often drowned the conversation. Mr Burnham and Mr Doughty were among the few who could make themselves heard effortlessly, above the machine – but those with feebler voices often had to shout, which only added to the prevailing sweatiness. In the past, when seated beside deaf colonels and infirm accountants, Paulette had often had cause to regret the introduction of the new machine – but today she was unreservedly glad of its presence, since it allowed her to speak with Zachary without fear of being overheard.

'If I may ask, Mr Reid,' she said, 'where is Jodu now? What has become of him?'

'He's trying to earn a little money while the Ibis is being refitted,' said Zachary. 'He asked me for a small loan so he could rent a little ferry-boat. He'll be back on board when we're ready to sail.'

Paulette thought back to the lazy days when she and Jodu had sat in the trees of the Botanical Gardens, watching the ships on the Hooghly. 'So he is to have his wish then? He will be on your crew?'

'That's right: just as you wanted. He will be going to Port Louis with us when we sail in September.'

'Oh? He will go to the Mauritius?'

'Yes,' said Zachary. 'Do you know the islands?'

'No,' said Paulette, 'I have never been there, although it was once my family's home. My father was a botanist, you see, and in the Mauritius there is a very famous botanical garden. It was there that my father and mother were married. That is why I have a great envy to go there…' She broke off: suddenly it seemed intolerably unjust that Jodu should be able to go to this island while she, Paulette, with all her prior claims, could not.

'Is something the matter?' Zachary said, alarmed by her pallor. 'Are you all right, Miss Lambert?'

'An idee came to my mind,' said Paulette, trying to make light of her sudden turn of thought. 'It struck me that I too would love to go to the Mauritius on the Ibis. Just like Jodu, working on a ship.'

Zachary laughed. 'Believe me, Miss Lambert, a schooner's no place for a woman – lady, I mean, begging your pardon. Especially not someone who is accustomed to living like this…' He made a gesture in the direction of the loaded table.

'Is that indeed so, Mr Reid?' said Paulette, raising her eyebrows. 'So it is not possible, according to you, for a woman to be a marin?'

Often, when at a loss for a word, Paulette would borrow a term from the French, trusting that it would pass for English if pronounced exactly as it was spelled. This strategy worked well enough to provide reason to persist, but every once in a while it produced unexpected results: from the look on Zachary's face, Paulette knew that this was one such occasion.

'Marine?' he said in surprise. 'No, Miss Lambert, there sure aren't any woman marines that I ever heard of.'

'"Sailor",' said Paulette triumphantly. 'That is what I meant. You think it is not possible for a woman to sail under a mast?'

'As a captain's wife, perhaps,' said Zachary, shaking his head. 'But never as a member of the crew: not a sailor worth his salt would put up with that. Why, there's many a sailor won't so much as utter the word "woman" at sea, for fear of bad luck.'

'Ah!' said Paulette. 'But then it is clear, Mr Reid, that you have never heard of the famous Madame Commerson!'

'Can't say as I have, Miss Lambert,' said Zachary with a frown. 'What flag does she fly?'

'Madame Commerson was not a ship, Mr Reid,' said Paulette. 'She was a scientist: to be precise, she was my own grand-aunt. And I beg to inform you that she was but a young woman when she joined a ship and sailed all around the world.'

'Is that a fact?' said Zachary sceptically.

'Yes, indeed it is,' said Paulette. 'You see, before she was married, my grand-aunt's name was Jeanne Baret. Even as a girl, she had a passion most heated for science. She read about Linnaeus, and the many new species of plants and animals that were being named and discovered. These diverse facts made her burn with the volontee to see for herself the riches of the earth. What should happen then, Mr Reid, but that she should learn of a great expedition, being organized by Monsieur de Bougainville, with the intention of doing exactly that which she wished? This idee set her afire and she decided that she too, by all hasard, would be an expeditionnaire. But of course it was not to be expected that the men would permit a woman to join the ship… so can you imagine, Mr Reid, what my grand-aunt did?'
