I just finished The Wolf In the Garden and was surprised to find virtually no discussion of the novel across the entirety of the internet. I love colonial era horror, Revolutionary War-era history, and 1930s American literature, so when I discovered this book in my quest for a good werewolf story, I knew I'd hit the trifecta.
My first comment on the story is how remarkably similar it was to Dracula, which was only 40 years old at the time The Wolf In the Garden was originally published. You have your affluent outsider (Dracula/Saint Loup) new to town with some obvious evil energy, shape-shifting, strong influence over some of the main characters. Your case of male leads fighting to protect the female lead. Character parallels in John Harker/Robert Ferrier, Mina Harker/Felicity, Van Helsing/Sackville. There's even a carriage chase at the climax. However, I think The Wolf In the Garden is a little more palatable for modern tastes in its brevity. There is still quite a bit of exposition, but nowhere near the level of Dracula. And it even features a treasure hunt as a side-story. Goofy as it may be, it added a level of intrigue to the werewolf mystery.
For a book written in the 1930s, I really enjoyed the descriptions and imagery around the action sequences. The first encounter with old Peter's "ghost" and Squire Killian and Robert, the wolf attacks which we were able to witness as readers, the final chase and confrontation in the garden.
Narratively, I enjoyed the telling of the story from Robert's perspective far in the future (which we only learn around 3/4 of the way through the story). He seems to be honest about his recollections and often admits that his thoughts in the moment may not have been exactly as he's currently describing them many years later.
I admit I was a little confused at Saint Loup's motives at the end, taking Felicity to New York and then back to his home. Was all of the buildup really just for an evening of depravity?
I'll finish my initial thoughts on this book with my main criticism, which is the way Alfred Hoyt Bill handles the topic of slavery within the story. And by that I mean basically brushing it aside and treating it as normal within the context of the time and hardly pointing out any of the atrocities surrounding it. This may have been a true depiction of the 1790s in New York - a few "servants" as they called them then around the village, mostly brushed over. And it may have been a common way to handle the discussion of slavery in the 1930s. But the treatment of Vashti, Hebe, Henry, and Barry as tertiary characters to be ordered around and treated poorly by the main characters hurt the story. And the casual mention of Felicity as the proprietor of over 300 slaves within the context of explaining why she wasn't a stranger to sex because she'd seen many slaves give birth was impossible to count against her character (or any of the characters for that matter). It was especially ironic to consider the many humans enslaved to Uncle Barclay and Felicity and still try to take Robert and the rector seriously as they describe and fight against the evil that is Saint Loup, paying no mind to the evil that is slavery in their daily lives.
