After the crimes that took place in Bremen, Erik Vogler urgently needs a break. The doctors have prescribed him a course of rest, as he is haunted by nightmares about the white king night after night. So he accepts the invitation of his grandmother Bertha to spend a week with her in a luxurious spa. Of course, he could not have imagined that a relaxing mud bath could turn into another nightmare.
With her seemingly repulsive main character, Spanish writer Beatriz Osés has created one of the most original detective novels in recent years, one that captivates and surprises us on every page. This is a detective story with paranormal elements and elements of horror. (taken from the general page of Malinc Publishing House)
