Written in 1905, it is one of Wallace's many popular thriller novels. „Four Just Men" was the start of a series about a determined band of European vigilantes who decide to kill off people in the world whom the law cannot punish. Their ingenuity and ability to keep several steps ahead of those who would thwart them, including police, are the essence of the plot. When the British Foreign Secretary Sir Philip Ramon decides to push through a law which will allow the enforced return of political refugees to their countries of origin, he becomes a target of the Four Just Men. These are iconic stories of adventure, intrigue and retribution set in the time immediately following the First World War. Highly recommended for people who like to treat a mystery story as a solvable riddle.
