Atormentada por los rumores de que envenenó a su prometido, Lucinda Bromley vive alejada de la sociedad del Londres victoriano. De vez en cuando, sin embargo, se embarca en la investigación de un asesinato, pues Lucinda tiene una cualidad excepcional: es capaz de detectar casi cualquier tipo de veneno. Para descubrir el asesinato de un noble, Lucinda solicitará los servicios del investigador psíquico Caleb Jones. La atracción entre ambos será inmediata, pero pronto se verán en medio de una funestra conspiración cuyos orígenes se remontan a los primeros tiempos de la misteriosa Sociedad de los Arcanos.

"If Lucinda Bromley doesn't discover who stole her fern, she could end up being charged with murder. Lucinda frequently used her unusual psychic gift to discern death by poisoning to help the London police, but when a nobleman is poisoned by a compound containing elements of a rare fern, one that can only be found in her conservatory, Lucinda knows she better act quickly. To help her find the real murderer, she hires Caleb Jones, a "psychical investigator." Believing there is a connection between Lucinda's fern thief and a deadly dangerous secret society, Caleb agrees to take the case, but he never expected to become so distracted by his new partner in detection or to find himself flummoxed on so many fronts."--John Charles.
