I was pleased when this book moved the action away from Flavia's family home. There are only so many (attempted) murders that an occur in a small village before you start thinking of Midsommer and the high levels of improbability become a distraction. 
 Another great story, although I look forward to getting my hands on a copy of the latest book (I'm relying on my local library service to come through soon) so I can find out what happens to Flavia when she gets home!
