The Essence of Malice By Ashley Weaver

When Amory Ames’s husband Milo receives a troubling letter from his childhood nanny, Madame Nanette, the couple travel to Paris where they become embroiled in a mystery surrounding the death of a famous parfumier. Helios Belanger died suddenly, shortly before the release of his new, highly anticipated perfume, and Madame Nanette, who works for his family, is convinced that her employer’s death was not due to natural causes.

The more Amory and Milo look into the motives of industry rivals and the Belanger heirs who are vying for control of his perfume empire, the more they are convinced that Madame Nanette may be right. When secrets unfold and things take a dangerous turn, Amory and Milo must work quickly to uncover the essence of the matter and catch a killer before the scent goes cold.
