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 coldblooded killer bent on murder. While relatives gather around her hospital bed the tension builds as an ingenious device helps Mrs. Wingfield convey a message that could solve the mystery.
