The Invisible Guardian

Dolores Redondo

In the first of a trilogy, Inspector Salazar returns to her home town Elizondo, near Pamplona, to head the search for a serial killer. So far, so predictable but Salazar is an intriguing character with very good reasons for leaving Elizondo, and I found this a very satisfying blend of police procedural and supernatural thriller, featuring some truly terrifying characters.

Zabalza came back with two printed sheets on which several sentences appeared to have been underlined.
... 'confirms that the officers are linking the case with the recent murders of young girls in the Baztan Valley. The killer slashes their clothes and hairs of non-human origin have been found on the bodies. A terrible lord of the woods who kills within his domain.'
