I picked this up mostly because London! and Sherlock Holmes! and girl detectives! and pretty cover! I wasn't expecting a new favorite or anything, but it was a quick, enjoyable read that didn't disappoint. Sure, the plot was loose at times, and a lot of parts either felt out of place or weren't fully developed, and the writing wasn't anything amazing, but overall it did its job and I liked it. Dora and Peter were both endearing characters and I'll definitely be reading any future books.
