The first performance of Inadmissible Evidence at the Royal Court Theatre in London on September 9, 1964, by the English Stage Company, was a resounding critical and popular success. It also reinforced John Osborne's status as England's most important post-World War II dramatist. The play chronicles the mental disintegration of middle-aged, London solicitor Bill Maitland over the course of two days as he experiences the breakdown of his professional and personal life. Osborne combines elements of realism and theater of the absurd as he illustrates Bill's nightmarish world that ironically Bill has constructed himself. It results from his inability to face up to his own failures as well as to the pain he has caused those who have tried to save him. In this poignant study of one man's struggle to avoid harsh truths about himself and his relationships with those closest to him, Osborne presents a compelling portrait of the devastating causes for spiritual and emotional bankruptcy.
