Death Angels by Ake Edwardson

In Gothenburg, someone is brutally killing young male tourists from England. Similarily, in London, men from Sweden are turning up dead. Erik Winter, Sweden's youngest ever Chief Inspector, heads the case there, while in London Steve Macdonald is investigating. The connections seem to be the degree of violence, the staging of the crime scenes and the choices of victims. Winter heads to London, figuring that liaisoning with Macdonald can only help solve the crimes. Will the detectives be able to find the murderer before he kills again? Death Angels is the first book in the Erik Winter series. Three subsequent books have already been published in English. While Death Angels is important because it shows the beginning of Winter's career as a Chief Inspector, I enjoyed some of the other books in the series more, such as Frozen Tracks.
