‘Gaslight’ is a classic Victorian, psychological thriller – atmospheric, tense, emotional and, yes, distinctly ‘creepy’. Is it understandable that Mr. Manningham is increasingly irritated by his wife’s forgetfulness and fragile state of mind? Are strange things really happening? Why are things disappearing? What is going on in the attic and what makes the light bulbs flicker? Enter ex-Inspector Rough to try and solve these questions – but can he? First produced in 1938, this wonderful play has been filmed twice, winning Ingrid Bergman an Oscar. Here is where the idea of ‘gaslighting’ first originated.
