Flavia is free to race around on her trusty bike, digging into newspaper archives, talking to old-timers, and poking through the belongings of a lodger at the village pub, who also happens to be a chemistry whizz!!
Because the story is told from Flavia's point of view, you go through the investigation with her; both its steps and missteps. You also see the logical and emotional process at work while she solves the crimes!
I was pleased to learn this is the beginning of a six book series. This book won the Dagger award, and I highly recommend it.
