Mario Conde is facing a failing body, a slower mind, and a decrepit country, in which both the ideals and failures of the Cuban Revolution are being swept away in favour of a new worship of money. Rescue comes in the form of a new case: an old Marxist turned flamboyant practitioner of Santeria appears on the scene to engage Conde to track down a stolen statue of the Virgen de Regla - a black Madonna. This sets Conde on a quest that spans twenty-first century Havana as well as the distant past, as he delves as far back as the Crusades in an attempt to uncover the true provenance of the statue.
