On the peaceful summer residential allotments in Simrishamn, a dog is killed. A few weeks later, so is one of the plot holders. She is a woman who had access to many secrets that certain locals wouldn't want to come to light. As Anita Sundström's team is brought in to investigate, the chief inspector also has to deal with the disappearance of a British archaeology student who has gone missing in Sweden while searching for an ex-colleague, who has also vanished. The case, brought to her by her long-time, long-distance partner, Detective Kevin Ash, who has run into a dead end in the UK, seems to be linked to two separate archaeological digs – one in Skåne and the other in the famous Viking centre of Birka. So, what has this all to do with a Scanian Viking who once fought in the Varangian Guard for a Byzantine emperor? Anita Sundström needs to find out before another life is lost in the tenth Malmö Mystery.
