“Mysterioso” opens the series of novels by Swedish master of the detective genre, Arne Dahl, about investigations of the “Group A.” In quiet, proper Stockholm, a serial killer hunts oligarchs, and the frightened Swedish State Criminal Police creates an elite team of investigators led by the experienced Jan-Olov Hultin. They must neutralize the mysterious criminal who, at night, slips into the victims’ mansions and kills them with two shots to the head to the sound of jazz.
Very soon three circumstances come to light: during a magical summer night of 1958, sound-recording engineer Ray Fowler got drunk during a Monk concert and didn’t turn off the microphone in time; in the mysterious Order of Mimer a sudden split has formed; and the girl who worked as a caddie during a golf game committed suicide. Perhaps all of this is a chain of links; perhaps it’s just a series of random coincidences. Readers of the magazine “Reader’s Digest” named Arne Dahl the best writer of suspense detectives.
