Georgette Heyer knows how to write, to construct interesting characters, put them in interesting situations, add a bit of humor and deliver most entertaining books to us. This is one of them. Using the stock setting of the Old Mansion and assorted members of the family, one of whom, the holder of the purse strings, is a Nasty, she sets up a murder. Of course, there is the quite normal charming daughter, and, down from Scotland Yard, a most personable detective. There is sufficient misdirection and puzzlement to satisfy the more traditional mystery lovers among us, and sufficient idiosyncrasy to amuse all of us. Not a deep, complex read, it should be satisfying to many.
