El detective privado Cormoran Strike, que se halla en Cornwall visitando a su familia, es abordado en plena calle por una mujer que le pide ayuda para encontrar a su madre, Margot Bamborough, desaparecida en 1974 en extrañas circunstancias.
A pesar de que nunca se ha enfrentado a un caso ocurrido tantos años atrás y de ser consciente de las escasas posibilidades de éxito, Cormoran Strike y su compañera en la agencia, Robin Ellacott, que sigue atrapada entre un divorcio tormentoso y sus sentimientos hacia Cormoran, acaban aceptando el caso.

A medida que se van sumergiendo en la investigación, los dos detectives se topan con una historia terriblemente compleja poblada de cartas de tarot, un asesino en serie psicópata y testigos que son poco de fiar. Porque incluso un hecho ocurrido hace décadas puede ser mortal.

ENGLISH DESCRIPTION

A breathtaking, labyrinthine epic, Troubled Blood is the fifth Strike and Robin novel and the most gripping and satisfying yet.

Private Detective Cormoran Strike is visiting his family in Cornwall when he is approached by a woman asking for help finding her mother, Margot Bamborough--who went missing in mysterious circumstances in 1974.

Strike has never tackled a cold case before, let alone one forty years old. But despite the slim chance of success, he is intrigued and takes it on; adding to the long list of cases that he and his partner in the agency, Robin Ellacott, are currently working on. And Robin herself is also juggling a messy divorce and unwanted male attention, as well as battling her own feelings about Strike.

As Strike and Robin investigate Margot's disappearance, they come up against a fiendishly complex case with leads that include tarot cards, a psychopathic serial killer and witnesses who cannot all be trusted. And they learn that even cases decades old can prove to be deadly . . .
