She did marry – Edinburgh surgeon John Bishop – but he died five years later, leaving her well-off. Single, full of fancies and with a boundless thirst for knowledge inherited from her polymath mother and her father, a barrister turned clergyman and keen amateur botanist, she set forth in earnest once again.

Most of the time she travelled solo. Interpreters, porters and the like were a necessity, but she didn’t feel the need of a chum. Once – armed with medicine chest and revolver – she joined forces with a British military expedition across the desert from Baghdad to Tehran, but this wasn’t because she thirsted for human company: she just fancied the adventure.

Wherever Bird travelled – America, Asia Pacific, Arabia – it would not have been easy going. Even assuming that I’d have been allowed to tag along, I’m not sure how much use I’d have been. I could have strapped up her broken ribs after she fell from her horse fording a river in Ladakh, India, but I’d have been quaking in my boots when a mob tried to set fire to the house where she was staying in Sichuan, China (a posse of soldiers turned up in the nick of time). I doubt I could have added much to the charm she exercised on the Maharajah of Kashmir to donate the land she wanted for a hospital, nor would I have had the patience to sit through the meetings to set up orphanages – even if I had been able to speak Korean or Japanese. I certainly wouldn’t have proved much of a rival to the one-eyed, poetry-loving desperado Rocky Mountain Jim, to whom she briefly lost her heart (but not her head) in Colorado.

I picture myself and Bird sitting across the campfire at night, her knitting, me trying to think of a good conversational opener. After all, this was the woman who tartly declared: ‘I still vote civilisation a nuisance, society [specifically Britain’s stuffy middle-class milieu] a humbug and all conventionality a crime.’

Bird’s default setting was ‘off the beaten track’. It wasn’t sufficient to sail halfway round the world to Japan – she wanted to visit the archipelago’s original inhabitants, the Ainu, in northern Hokkaido. And she did. Small wonder that in 1892 she was invited to join the Royal Geographical Society, which had been chaps-only since its establishment 62 years earlier.
