Medusa

When a shadow from the past re-awakens, successful surgeon Axel Glenne's life turns upside down. Soon after, a woman's body is found in Nordmarka, a forest north of Oslo. Items found near the body suggest that the killer is leaving a message, and while this death is being investigated, another woman is murdered. The similarities are too close to be coincidental - and it appears that Axel Glenne has a connection to both victims.
