I read E.T.A. Hoffmann's collection of short fiction ages ago, and "The Sandman" ranks way up there on my list of dark fantasy / gothic fantasy short fiction (second only to "Rappaccini's Daughter", another short story that's set the fire under the muse's feet a few times through the years). The idea of a mannequin coming to life and fooling people was an itch I couldn't ignore and ended up scratching it until Automata came out of it.
Okay, granted a magically infused doll fooling people into thinking it's a real woman is a bit of a stretch, but that's a damn good prompt for a story.
And Venice is back to being the ideal location for a darkly magical story -- I actually refer to it as something like folktale horror -- and in the Curiosities universe, it's still a city on the water with canals and palazzos and extravagant ballrooms while guarded by special supernatural protector knights (in a manner of speaking). The guardians in this book are the Maschere ("masks" in English), and they're dressed in all black with white masks -- the traditional Venetian costume of the bauto and the tabarro, and they stand well over six feet tall.
They also hunt supernatural threats in their own way.
The automata are all part of a collection of inventions by a noblewoman. One of them goes rogue and comes after Alexej once he takes that fatal step of wishing for love after suffering humiliation in his efforts at forging connections with possible partners.
Loneliness and the threat of death from a weak constitution and a lifelong dependence on medication make him vulnerable to making cursed wishes, which is the overarching theme in all three books I wrote for the Curiosities collection. Alexej and his adoptive family first made their appearance in Dollhouse, the book that debuts the not-quite-series, hence the book's opening referencing the fate of Alexej's best (and only) friend, Arthur. You don't need to read Dollhouse, though, to enjoy Automata as each book in the collection was written to stand alone despite events all taking place in the same universe.
