Geralt did not meet Anna Strenger, the Bloody Baron's wife, when he Visited Crows Perch. Some time before his arrival this woman had disappeared in unexplained circumstances along with her daughter, Tamara.
Geralt did, however, receive a detailed description of the missing woman. Anna was a comely forty-something woman with green eyes and hair dark as raven wings which she kept tied in a tight bun behind her head.
Geralt discovered that Anna's marital life had not been working out as well as she might have hoped. She had recently been pregnant, but lost her child for unknown reasons shortly before her disappearance.
When Geralt pushed the baron about the matter, the ugly truth finally came out. Desperate and miserable, Anna had fled, taking Tamara with her, after her drunken husband beat her badly.
The baron was convinced Anna had miscarried because of his actions, but Geralt was not SO certain about this - he couldn't stop thinking about the strange talisman meant to ward off evil power Anna had received from the pellar.
During their heart-to-heart the baron gave Geralt a somewhat clearer image of the Strengers' married life.
