A gripping tale of sex and murder... At the Butterfield Institute Dr Morgan Snow, New York’s top sex therapist, sees everything from the abused to the depraved. The Scarlet Society is a club of powerful and sexually adventurous women. And when a man they’ve recruited to ‘dominate’ goes missing, they are frantic with worry. Then a photograph of his lifeless body is sent to a newspaper and their lives become a twisted nightmare. Feeling violated, the women turn to Dr Morgan Snow. But what starts out as counselling quickly becomes a murder investigation. As a second, then third member disappears, Dr Snow finds herself drawn into the dark, tangled secrets of her clients—and a terrifying chase to stop a killer before it’s too late.
