so EBD no doubt intended to join in the condemnation but might instead have sent hundreds of young girls to their nearest bookshop to find out what the fuss was about

And of course, decades later, I'm now tempted to look it up to see if it's as exciting as all that!
Joey and Patricia is on the onedrive my lamb. Although please don't take that as a recommendation! It is quite short at least. I really enjoyed Helen McClelland's biog of EBD but both her fill-ins left me cold.
Maybe the inevitability of near-death (necessitating doctorly rescue, which in turn necessitates instant betrothal) combined with the absence of Jack is what made EBD's version of India slip quietly away without ever being published. Maybe there was no way that Joey could go across the world adventuring and still want to come back home to marry her BIL's junior colleague, brother of her former teacher, friend of the family type bloke.
I am about a quarter of the way into Jo to the Rescue for the first time (thanks to Cheddar!)
I'm glad to be reading it, but I can't imagine it'll ever be a favourite. I can't seem to warm to dear sweet wet Phoebe. I was willing to put aside my dislike of Jo at this age especially (she is hard going when she's floating about being all smug mother, isn't she?) because the idea of the quartet holidaying together with their various children plus Sybil is actually really nice, in a way which is a bit similar to the first half of Maids of LR only a bit more grownup because they all have their children with them. It's almost like the fantasy single parent house-share. And then bloody Jack turns up!
It's quite interesting on the image of parenting, though (which obv I would have paid zero attention to as a child!). The youngest children are explicitly still breastfeeding at night, which is quite interesting. Lots of stuff about whether children are trained to sleep through noise or accustomed to quiet. Very nice bit where the others insist that Frieda, who has recently had her second child, should have a lie in and breakfast in bed while the others look after her firstborn. The requisite passage about spanking in exceptional circumstances if nothing else will fix it.
Also a slightly bonkers bit where Jo appears to have dictated that the families can all visit Phoebe in succession, with a 20-min slot each.
It reminded me a little of the bit towards the end of Reunion where Jo appears to arrange a sort of parade of friends and relatives past Grizel's hospital window.
