The theme is certainly far from being moose, and even process can be of a fad. It is true that the serial-killers have always fascinated and bewildered society. But Rapilly manage to distinguish itself from current production on the subject. In the investigation of heroes, interesting in itself, it adds universe techno and rave, an element of curiosity and discovery for a readership probably unfamiliar with this universe.
The atmosphere festive and excessive lends itself perfectly to the seraglio-killer action and also induces an aesthetic component to this novel. Music plays an important role in this plot, but I would not say anything so as not to lift the veil on the inner workings of the murders and exciting "hunt" for the man.
