This is basically Sherlock Holmes for the 'girls in STEM' era, but it actually works because it's a good story first and a 'lesson' second. It doesn't lecture; it just lets these two geniuses be messy, smart, and adventurous.
It’s 2015-era writing, so it moves at a modern clip and doesn't suffer from the 'boring classic' syndrome. If your kid likes puzzles, history, or just watching two smart girls outwit a bunch of adults, this is an easy addition to the bookshelf.
