] Bergman was very effective in the role of the vulnerable young wife who becomes helpless as she experiences a debilitating nervous breakdown and near insanity while living with her mysterious husband in the home where her beloved aunt was murdered.While wearing the locket, Harry stripped down and entered the freezing water, but found himself strangling and drowning when the locket fought back, sensing the threat of its own impending destruction.As they ride down the main road, Calloway notices the attractive dark-haired woman who was at the graveside walking towards the city.Themes of betrayal, corruption, fatalism and a cynical, perverse, and a morally ambiguous atmosphere are all interwoven and entangled together in a confusing and convoluted dark plot (mixing narrative flashback with linear narrative) with both double- and triple-crosses.
