A very quick read. Good little mystery. Unfortunately, though, I always have a problem with (view spoiler)[mysteries in which the criminal (tho in this case not a murderer) asks for their own crime to be investigated. I just don't buy it. (hide spoiler)] 
 I love Flavia - "I'm here as a brain, not as a female!" Looking forward to starting the audiobook of #7 in the near future!
