I love the opening scene with Watson and Holmes bickering over his writing, Holmes is bored and restless, Watson doesn’t quite know what to do with him (or he does, but he can’t WRITE that for the Strand!). Watson even notes Holmes is smoking a particular pipe that indicates he’s in a “disputatious mood”. I see the scene in the train on the way to the case, as a continuation/development of this conversation, the different ways they see the world, but this time coming closer to mutual understanding. Action is good for both of them.
Violet Hunter is the prime example of the young orphan woman, working as a governess, entirely subject to the whims of her employers, and who knows she’s getting in a bit over her head, but what else can she do? I get the feeling that ACD wrote about this kind of issue a lot because it concerned him personally.
Rucastle is a super creepy “charming” abuser, who has nearly driven his daughter to death, who knows what happened to her mum, and has succeeded in so cowing his second wife that she just keeps her head down in a “better you than me” attitude. The vicious dog and the nasty son reflect aspects of Mr Rucastle. He exemplifies what Holmes was talking about in the train: under his charming exterior (pretty countryside), passes a chilling, nasty, greedy man who is more than willing to harm his own daughter for money. He gets away with it because of the isolation, his daughter literally incarcerated in the house, his wife and son under his control.
It makes Mrs Toller all the more remarkable, I wish we had more about her. Somehow she has hung onto her wits and self respect, does what she can to help and protect Miss Alice (and help Mr Fowler get her away safely). I am sure she would have tried to protect and help Miss Hunter too, if only they had had a little more time to get to know each other. At first glance, it seems like the Tollers will be a reflection of the Rucastles: coarse, drunkard Mr Toller must be dominating quiet Mrs Toller, but instead they are the opposite. They are cagey allies of Miss Alice, and while Toller may be a drunk, he makes sure to put the ladder in place for Mr Fowler before he goes to drink up his alibi.
There is so much mirroring in this story, and between it and other cases. Holmes helps several young women to escape from abusive fathers, husbands, or employers. As in ABBE, the “Mr. Right” is a sailor, but at least here Mr Fowler doesn’t have to commit murder to rescue his love. Violet’s hair color is key to her selection, as in REDH, and like Mr Wilson, is not the intended target, but a means to it. Rucastle getting mauled by his own dog, reminds me of the lion-mauling in VEIL. Watson shoots the dog, as in HOUN. Miss Alice is a target because of the money she will get control of when she marries, like the Stoper sisters in SPEC, or Mary Sutherland in IDEN. There are probably more connections, those were the ones i noticed.
