Three Act Tragedy is a detective novel by Agatha Christie published in 1934. Another murder, yay!

Hercule Poirot, now retired, is once again pulled from his boring pumpkin farming into a new drama when a priest suddenly died in a party he was attending. The story sees Poirot, accompanies by other major characters: Charles Cartwright, an old famous actor, Hermione "Egg" Lytton Gore, an energetic young woman, and Mr. Satterthwaite, Charles' friend; trying to solve the mystery around the priest's death and the plausibility of a homicide.

The title Three Act Tragedy here, most likely, referred to the term "three-act structure": a storytelling model that divides a story into three parts: Setup, Confrontation, and Resolution. The theme of theatrical performance is also apparent in this novel, notably, because of Charles' involvement in this case. While we see once again how Poirot applies his hard-cold logic on this case, the spotlight belongs to the three other members of his team, Charles, Egg, and Satterthwaite. We delve deeply into the thoughts of a master performer, an acute audience, and other seemingly minor roles but had a deep impact on the story. And their interactions with the old-classic Poirot is another pleasure read here.

Overall, this is another brilliant story by Agatha Christie. I love every bit of it and hope to read more and more from the writer.
