Blackbird Sisters Mysteries

I really need to have a good mystery at my fingertips at all times.  Since I recently ran out of books from the approximately 15 series I keep up with, I added this one.  Nora Blackbird and her sisters grew up on Philadelphia's mainline in a well to do old guard family.  Just the descriptions of the clothing Nora wears make these books interesting to me.  Her grandmother left her a bunch of Chanel and Schiaperelli and she has to wear them to her work assignments/high society soirees.  I am only on the third book right now so I am interested to see where the protagonist's love life takes her.  Fortunately I have 9 books left to enjoy while finding it out.
