Red Queen by
Juan Gómez-Jurado

Antonia Scott―the daughter of a British diplomat and a Spanish mother―has a gifted forensic mind, whose ability to reconstruct crimes and solve baffling murders is legendary. But after a personal trauma, she's refused to continue her work or even leave her apartment.

Jon Gutierrez, a police officer in Bilbao―disgraced, suspended, and about to face criminal charges―is offered a chance to salvage his career by a secretive organization that works in the shadows to direct criminal investigations of a highly sensitive nature. All he has to do is succeed where many others have failed: Convince a recalcitrant Antonia to come out of her self-imposed retirement, protecting her and helping her investigate a new, terrifying case.
