Their mutilated remains form part of a macabre puzzle of rape and torture, the pieces of which police chief Padura under pressure from a mysterious painter must put together. In an environment in which drug cartels are the law, Padura must start a path to ruin without return towards that place where blood is the bile of the heart. Gregorio Leon manages to construct not only an impeccable work in the use of the Mexican expression, but a solid and well-structured novel marked by an agile and thrilling style that makes reading impossible to stop, except for a brief moment of held breath as the reader contemplates the terrible and dark reality presented in the book."
