Dandy Detects: A Victorian San Francisco Story - M. Louisa Locke
It's actually a short story, but it wasn't bad for a really quick read. I usualy prefer novels, but this was fine. I was stuck between rating it a 2.5 or a 3, but I went with the 3. If you don't care for short stories, pass this up, but if you like them, you could do worse than Dandy Detects.
