The title of the novel refers to the Spanish name for the cartoon character Betty Boop and it was affectionately given as a nickname by Jaime Brena, a crime reporter for a Buenos Aires newspaper, to a leading crime novelist Nurit Iscar some years ago. Brena is now being pushed out of his job and Iscar is reduced to more mundane writing after her last novel failed to please the critics. But when a wealthy man is found with his throat cut in a gated country club community, Brena and Iscar become involved in investigating the murder. Brena’s boss discovers that the newly-appointed young graduate crime desk chief needs guidance and lacks useful contacts and Brena is back on the job. Iscar is hired to write a piece on the crime scene – but this is also a ruse by which the editor can attempt to rekindle a relationship with her. The subsequent investigation unearths a story which can be traced back to events many years ago involving wealthy families in Buenos Aires and the narrative has a darker ending than might be expected because of some of the earlier exchanges.
