I'm glad you liked it! I've been reading Melissa Scott for ages. Some of my favorites by her are Point of Hopes and its sequel Point of Dreams (fantasy-mysteries set in a well-researched Renaissance-analogue world in which magic works), The Kindly Ones (science fiction featuring a society in which many infractions carry a penalty of "social death" creating an underclass of "ghosts"), Dreamships (science fiction about a crew of pilots hired to test a computer system that may possibly be the first true artificial intelligence), and The Armor of Light (excellent alt-history sixteenth-century England, with just a touch of magic). Scott is really good at world-building; she's aware of things like economic hierarchies and material culture that many other authors take for granted. Also, she writes lots of great queer characters.

I speculated to someone that the lack of Britpicking in Death by Silver might possibly have been requested by the publisher. The book was geared primarily to an American audience, and to Americans who don't know better, some British English structures (like "got" where Americans would say "gotten") sound ungrammatical. Since a lot of real British books are Americanized for publication here, it wouldn't surprise me.
