Georgette Heyer will always be one of my all time favorite authors.  He characters are well developed, her understanding of people is immense and the plots well crafted.  In this book there is a long list of suspects and no one who won't speak ill of the newly departed.  But this story is different in that all of the suspects have no desire to be implicated in the crime and are only too happy to do whatever it takes to make sure suspicion is diverted from them.
