The police is possibly one of the most deeply rooted genres in the imagination of all of us. Through cinema, photography, comics, painting and, of course, literature we have participated in the fears of the victim, the intrigues of the criminal or the investigations of the investigator on duty. The tale has not escaped its attractive world of mystery either. Therefore, this anthology will leave its mark and, if we are attentive to its clues, we will know if there is always a motive, if there is the perfect crime and if, in addition to the butler, there is some other culprit.
