Twisted Endings

I recently read a book by Jeffrey Archer. A Twist in the Tale is actually a collection of short stories. I especially liked 'The Perfect Murder'. It is a story of a man, who, on one of his visits to his mistress, finds that she has deceived him. He waits till the other man leaves and enters her apartment. He confronts her, striking her to her death.

When the news hits the papers the next day, the protogonist anonymously calls the cops, and talks of the other man, whom he had seen leaving the lady's apartment. He gives details of his appearance, his car's make etc.

When the other man is arrested, he feels safe but keeps in touch with the case through newspapers. Did he escape completely? One would think that the author will work on justice. But unpredictably, there is a twist in the tale. When the court trial starts, he visits every session. You get a detailed description of the court proceedings. The accused is resigned to his fate. The jury has to make the decision of 'guilty' or 'not guilty'. The jury is finally ready to give the verdict. The judge asks the foreman of the jury to give his verdict. The protagonist stands up and says 'Guilty'.
