A group of wealthy vigilantes known as The Four Just Men are famous for their ability to punish criminals that have evaded the authorities.

In this collection of short stories, the Just Men set their sights not only on murderers, kidnappers, and embezzlers, but also on those wrongfully convicted. Often the pursuits of the Just Men require the unwitting assistance of the Assistant Commissioner of Scotland Yard.

The ten short stories in this collection were originally published separately in The Strand Magazine and the The Novel Magazine in 1921.
