The Strange Case of the Alchemist's Daughter

Literary mashups of public domain stories and characters, like Penny Dreadful, A League of Extraordinary Gentleman, and this book, are like opium to me. The daughters of several gaslight era mad scientists, plus Holmes and Watson, team up to solve a series of murders. A great deal of the book is about the formation and backstory of this group, so having gotten that out of the way, I'm looking forward to the next book and their adventures together.
