Serial killer Sebastian lived in Stockholm, Sweden, targeting single young women as his prey—the life of which was giving him a huge problem when he woke up every day in the morning. He then sought medical help from the psychiatrist Margareta, a married woman who was bored with her life, and this experience would alter Sebastian's life forever. In the book, you will also find a diary written by Sebastian as a young boy who lived in the Swedish countryside of Östersund. And the diary reveals a dark secret in his dysfunctional family.
