The Patient, known as Mrs. Wingfield, has been horribly injured in a fall from her balcony. Unable to communicate, it could have been an accident, attempted suicide or worse still a cold-blooded killer bent on murder. As relatives gather round her hospital bed the tension builds as an ingenious device helps Mrs. Wingfield convey a message that could solve the mystery.
Part of the triple bill The Rule of Three which also features The Rats and Afternoon at the Seaside.
Presented by Peter Saunders at the Duchess Theatre, London on 20th December 1962.
