'Chronicle of a Death Foretold' is a journalistic account of a murder, and not at all detective-like at that. In very first pages both the murderers and the murdered are revealed. It is only the writing style of Gabriel Marquez that makes this average story so enjoyable.
, Gabriel put the Santigo's flip side in the very beginning and then goes on to reveal the motive of murder which makes you believe that the murder may have some justification. Slowly though we realize he probably didn't do the thing he was murdered for. The character gets more humane in later half; still, his behavior, especially in those last moments is strange.
The chronicle shows you the hollow nature of society. A really, really expensive marriage wouldn't survive a day. Angela Vicaro's writing letters to her husband for seventeen years is something so weird that you won't believe it to be real if you didn't know otherwise - especially because she didn't want to be married to him in the first place.
Then there is the fact that only hours before the murder, the murderers were celebrating with Santigo - as they were all best friends or the fact that Angela's marriage failed because she wasn't a virgin - and because she was too nice to hide it. Although, you can't forgive her for sacrificing an innocent guy to save her lover (if we choose to believe the narrator). It seems, and this is perhaps the biggest failure of society that Vicaro brothers wanted to be talked out of committing murder but due to one reason or other, the many people who had learned about their intentions did nothing (or very little) to stop them.
