Two little known Priestley plays, which, while they are quite different, have important features in common.

The 31st of June is a comedy set partly in an advertising agency and partly in a medieval castle; Jenny Villiers is a serious play set backstage in an old provincial theatre. But both exploit elements of Time. In the 31st of June scenes switch between modern times and the middle ages, while characters move between both. There are kings, company bosses, princesses, fashion models, dwarves and two rival magicians. causing confusion and romance.

Jenny Villiers examines life in the Theatre. The doubts of the present are confronted by players from the past, and a jaded playwright recovers his faith in the Theatre.
Both plays were performed on the stage, but later rewritten and published as novels.
