I'm here solely because this is the first werewolf story from the werewolf's perspective; which is funny, because the literary device to present it is a book written in latin on the skin of said werewolf as a Stubbes-esque warning of his sins, read out by a later descendant, transcribed into french by a visiting englishman then finally translated into english and presented here. I mean, the words are in first person so it's more trivia than anything that impacts its original perspective, but whew.
And yeah, it's Weird Tales, it's pulp, and this is reflected in the writing. For this its greatest offering is the story it tells, which unfortunately doesn't have the timelessness offered by simply 'being first'. We're given something firmly in thrall with folk tradition and witch trial historicity: a vampiric wolf-leader, the cursed offering of power and riches, the witch-hunt. For all that, it's written with thrills and with a decent amount of horror; it's engaging and doesn't bother wasting its time hitting beat to beat of tearing about our poor protagonist.
For historical context, I'm pretty happy with the detail offered for being a werewolf perspective. There's no previous corpus like today's writers have for how to deal with it, and you can see the beginnings of all-to-common tropes being created here. For that, it notches itself to a clean 4 stars for me.
