The Curved Blades - Carolyn Wells

In this suspensful whodunit a mean-spirited and wealthy dowager is found murdered in her boudoir supposedly killed once by poison and also by a blow to the head. Most bizarre is the fact that she is found sitting in front of her mirror lavishly dressed wearing a fortune in pearls and gems. Her niece, her social secretary, her cousin managing her finances, a mysterious count and a maid acting rather suspiciously are the suspects. The police are getting nowhere so famous criminologist Fleming Stone is called in. However is it possible he is so taken with the primary suspect that she could prevent him from solving the mystery??? - Summary by Celine Major
