This work is a unique police anthology. This compilation has been formed around three of the biggest and most famous detectives of police novels. It presents stories led by Sherlock Holmes, a genius of the deduction and predecessor of the modern police story; by Hercules Poirot, the satirical creation of Agatha Christie; and Father Brown, the priest that applies religious dogmas to the solution of crimes. All these are big stories, with suspense that doesn't ever decay and with the characteristic of any great detective's novel, where the guilty party is that one that was least suspected. The interesting side of this collection is the possibility of knowing three personalities, probably eccentric, but very human, that lay a touch of humor to the tragedy which is, at last, what makes a novel of crime and punishment.
