The tragedy of loneliness at the pinnacle of power is 'Caligula.' The tragedy of absolute mutual misunderstanding is 'Misunderstanding.' The tragedy of youthful maximalism, which became the basis for anarchic terror, is 'The Just.' And the complex, refined, and effective tragicomedy 'State of Siege' about the arrival of the plague in a medieval Spanish city. Two of the four plays included in this collection are among Albert Camus' most popular dramatic works, literally constantly appearing on world stages. The other two, by contrast, are known only to devoted readers and scholars of his work. However, all of them—written during the period when his friendship and rivalry with Sartre gave birth to both the philosophy and literature of French existentialism—bear the stamp of Camus's genius.
