This work investigates the lives and habits of various historical figures who defied social conventions to live according to their own idiosyncratic rules. Dame Edith Sitwell, a prominent poet and critic, utilizes her literary background to curate a collection of biographical sketches that highlight the absurdity and individuality of these figures. The book argues that eccentricity is a vital, if often misunderstood, component of the English character, providing a historical framework that celebrates non-conformity.

Critics frequently note the stylistic flair and wit present in Sitwell's prose, which elevates these sketches beyond simple biography. Scholars often cite this text as a classic example of character-focused historical writing that prioritizes personality over strict chronological documentation.
