The End of Temperance Dare

3.5
This novel read like a mystery from the sixties, almost like a grown-up Nancy Drew, finding her way in the world...I mean that in the best way: the ambiance, taking breakfast and tea in the winter garden while sorting out clues, not a swear word to be seen, dressing for dinner...

There's only one oddity. So, in this universe, ghosts can eat and drink, or is that a continuity error?
