Ah-med, in the meanwhile, had produced two chairs: Lynchong took one of them and assigned me to the other. Hardly had I absorbed my surprise at his earlier sallies than he began to speak again.

He was glad to meet me, he said; his name was Chan Liang, but I could call him Lynchong, or Mr Chan or whatever I wished: he was not partikler about this matter. And then, like a busy man of affairs, he turned with no further ado to the matter at hand: ‘I’m told you have something to show me.’

‘So I do,’ I said and proceeded to hand him the picture of the camellias.

The heavy-lidded eyes flickered as he looked at it, and an odd expression passed over his face. He tapped the picture with a fingernail that was at least two inches long.

‘Where’d you get this?’ he demanded to know and I told him it belonged to a friend who had asked me to make inquiries on his behalf. ‘Why?’ said he, in the same brusque way. I did not particularly care to be spoken to in that tone, so I told him it was because my friends wished to acquire a specimen for a botanical collection.

What would they pay? he asked me now, and I told him their intention was to propose an exchange, for they had with them an extensive collection of botanical novelties from the Americas.

Now a glitter came into his eyes, and his long fingernails began to scratch his palm as if to soothe the itch of acquisition. ‘What plants do they have? Have you brought any with you?’

No, said I. The plants were on board a ship that was anchored offshore, near Hong Kong.

‘That’s not much good to me, is it now? How’m I to know if they’re worth an exchange? These camellias, they’re monstrous rare they are – only to be found in the endermost places. I’m not one to trust to the figaries of chance, Mr Chinnery: I need to see the wares on offer.’

What was to be done now? I was at a loss for a moment and then an idea came into my head. I said: ‘Why sir, my friends could send me pictures to show you; one of them is a talented illustrator.’

He thought about this for a moment and then said yes, this would be all right, as long as I could show him the pictures soon – for it would take a while to have the golden camellias transported to Canton from the mountains where they grew.

‘I will write immediately, sir,’ I promised. ‘I do not doubt that I will have some pictures to show within the week.’

He had begun to fidget busily now, so I thought the interview was at an end and made as if to rise. But he stopped me by extending one of his long fingernails. ‘Let me ask you something, Mr Chinnery,’ he said. ‘This friend of yours – the one who owns that picture – is it possible that his name is Penrose? I forget his Christian name but I think they called him “Fitcher”.’
