Britannia, chapter 9

Yep, Betts was just stretching out the story. Jake insists on Britannia leaving that very night: he drives her back home and then drives straight back home again. The day after she gets home, she's back at work - this time, on a geriatric ward - and Jake has confronted Madeleine, who folds like a cheap card table and confesses all. The letter had been written to Britannia, as it turned out. So Jake calls Britannia's dad and arranges for a marriage license, and then picks up Britannia a few days later, interrupting her at her work and arranging for her to leave her job a few days early.
(That's not uncommon for a Betts doctor - arranging for a Betts heroine to leave her job - but it's always appalling.)
Of course she takes him back, despite his temper and high-handedness. But it's worth noting (because Britannia wouldn't ever think to do so) that if he hadn't insisted that she leave his house within half an hour of Chapter Eight ending, and he'd just kept her there for another day or so, everything would have been solved more easily.
Waiting also would have allowed Britannia's ankle to heal. The day before she leaves Jake's home, he's saying, "don't, I beg of you, over-exercise that ankle" (p. 155), and the next day he insists that she leave and, several days later, doesn't even ask after it, although she has been nursing without a day off for several days. Surely that would count as over-exercise? That he doesn't care or even seem to remember seems like a red flag somehow.
Next up: Caroline's Waterloo. I don't remember this one - though skimming the first page it all seemed familiar - but it seems to feature a marriage of convenience. Fingers crossed for that, and also that Caroline's Waterloo doesn't take me six years as Britannia did.
