"His best works will long be studied as models of playwriting and also as mirrors of the times. Rattigan can capture the social outlook of a whole period in Cause Célèbre (or the cause célèbre of The Winslow Boy). He can plumb the depths of obsessions rampant in a sedate residential hotel near Bournemouth, a crummy North London flat, a Public School, the active lives of Alexander the Great or T. E. Lawrence or Lord Nelson, the twisted lives of a financier with a charming but weak son or a rapacious woman out to snare her fifth and richest man who falls prey (willingly, self-destructively) to an ambiguous little ballet dancer. Variations on a Theme (whose plot is the last of those situations mentioned) is closely based on Dumas fils’ La Dame aux Camélias – but it is based on a steady and shrewd observation of English life in Rattigan's own time."
