Gaslight By Johnna Wright and Patty Jamieson, based on the play Angel Street By Patrick Hamilton will run from July 7-August 25 and will be directed by Martha Irving, who directed last summer’s hit production of Educating Rita. The thriller that spawned the term ‘gaslighting’, Patrick Hamilton’s 1938 play gave us the word we now use for an insidious form of mental abuse. Bella Manningham hears strange sounds and the gas lights dim for no apparent reason. But is she losing her grip on reason, or is it being loosened for her? Bella thinks she’s losing her mind. The truth might be far worse.
