A girlish game leads to a case of unmistaken identity and possibly a deadly duel! Preston Sturges film? No! Bram Stoker's 10th novel! Once again our intrepid author finds himself wrestling with the sexual mores of his time, in particular the proper role of women in the courtship process. My Stoker Bingo card had "emergency wedding", "deep dive into some specific science, history or law topic"—in this case, it was Scottish marriage laws, naïve lovers' misunderstandings of the opposite sex leading to travails, "woman-like", "man-like", "heavy reliance on contemporary pseudo-science"—thrice, this time: cell theory(?), the aether and psychology—and "grueling journey heroically undertaken".
The last is a 100 mile automobile drive from Scotland to England but, hey, people, it was 1909, and it was foggy!
The best parts of the book are the setup, which is ludicrous but delightful. The heroine strikes up a friendship with a ship stewardess who is coincidentally the former wet nurse of a great English Lord and who swears the only man who's good enough for our heroine is her former charge. This strikes all the ladies' fancies and, as a joke, they start calling her Lady Athlyne. The joke gets around and ultimately back to the hero, who decides he must investigate this scandalous, unladlylike behaviour incognito but has no idea where to look.
Another very good part comes at the end when one of the characters just bursts into hysterics at the absurdity of the situation. It had a genuine screwball feel at times.
The only really "bad" parts were the pseudo-science which from the perspective of writing in 1909 must not have seemed any different from his similar writings about good science (like the bogs in The Snake's Pass). It's probably only ten pages.
The only other thing I'd say is it might've been better if it were even lighter. Still, it's quite fascinating at this point to see Stoker still growing as an author.
I think his contemporaries may have also found his previous book-endings rather abrupt. His last one was just about perfect for the book as a whole. This one is actually about the last 10% of the book—a little on the long side, even, but he actually seemed to be having fun with his characters and ideas at that point, so I'll give it a pass.
Fun find: Appearance of the word "kodaking" which I used in my rewrite of Lair of the White Worm but worried about being too cute.
Next, and last: The Lady of the Shroud
