Limpieza de sangre / Purity of Blood

A woman has been found strangled in front of a local church. On her lap, a bag full of coins and a note "For masses for her soul." In a nearby convent for young society ladies, the chaplain is having "unconventional" encounters with his novices. Capitan Alatriste will soon discover how these two facts are connected by an entangled net of power, faith, and death.
