Request #206

For the longest time I’ve been trying to find the title of a book I read & loved in 2nd or 3rd grade. That would have been the mid-1980s. The books is set in Italy. An American family (or British) are there in the summer…either renting a place or having just bought a place. The story is a mystery/adventure told from one of the kids point of view. Any suggestions or ideas would be much appreciated! Thank you. Suggestion: The Famous Stanley Kidnapping Case by Zilpha Keatley Snyde
