This triple bill of one act murder mysteries combines: the light hearted comedy Afternoon at the Seaside, in which a detective attempts to find a priceless emerald necklace and the culprit who stole it; The Rats, a dark and chilling tale in which a pair of adulterous lovers find themselves lured to a flat, trapped like rats and framed for murder; and finally, The Patient, a tense thriller in which a woman has been hospitalised after seemingly falling from her balcony.

More about this play

Rule Of Three was first presented on tour in the United Kingdom in 1961 and subsequently opened at the Duchess Theatre in the West End in 1962.
A trio of playlets devoted, like the rest of her work, to whetting one's appetite for retribution.
