New investigations by pathologist John Eisenmenger. “Final Diagnosis,” the third novel by the English writer Keith McCarthy, continues the plot of his previous books (“Feast of Flesh” and “The Quiet Sleep of Death”) and involves the regular heroes of the author’s detective series - John Eisenmenger, Elena Fleming and Beverly Wharton - in a new complicated and dangerous investigation. The brutal murder of Jenny Muir, found in the garden of her home with her entrails and brain removed, brings back memories of a series of similar murders that rocked London four years earlier. The investigation that has begun reveals a whole series of questions, the answers to which, by force of circumstances, must be found by the heroes of the book. How is the new crime related to the previous ones? Which of the two Pendred twin brothers is actually responsible for the previous murders? And what is Geoffrey Bence-Jones, the respectable head of medical services at the Royal Western Hospital, hiding from his wife's past? Meanwhile, the murders continue, one crime is superimposed on another, forming a multi-layered detective intrigue, crowned with an unexpected and chilling ending.
