Story summary: Lady Ada Byron (Lovelace), 11-year-old mathematical genius, and Mary Godwin (Shelley), romantic and clever 14-year-old, decide to start a clandestine detective agency. Their first case seems open and shut--the criminal has already confessed! But there's something fishy going on, and Ada and Mary must use their not-inconsiderable wits to save the day.
Also features such memorable people as Percy Shelley, Charles Babbage, and Charles Dickens.
- Ada Lovelace!
- And Mary Shelley!
- Being detectives!
- It's purposefully historically inaccurate (e.g. Mary Shelley and Ada Lovelace being close in age). I liked this alt-history aspect, but I suppose it could be annoying to some. (There's an appendix with all the real facts at the end, so no one gets too mixed up.)
