Diamond Skulls

Lord Hugo Bruckton is a young Englishman who is the heir to a vast fortune. He is married to Ginny, who seems devoted and loyal to him, and they have a young son. But Hugo is haunted by jealousy, for he imagines Ginny in the arms of a colleague. He begins to spy on her and goes into a rage over her suspected infidelity. One night, after a social gathering with members of his old British Army regiment, Hugo and his friends go out for a drive. He accidentally runs over a woman, who dies at the scene. All but one of his friends urge Hugo to drive on. In his drunk state of mind, Hugo had imagined himself running over Ginny.

Over the next few days, a psychological war ensues. Peter, Hugo's business associate, wants to use the cover-up to leverage power over the estate. Jamie, who's dating Hugo's sister, wants to go to the police to report it. Hugo's family closes ranks as Ginny and the rest side with Hugo, who fears that his arrest and imprisonment will ruin the family's reputation. As the police investigation closes in on Hugo, the power struggle leads to deadly consequences.

At the end, Peter and Hugo murder Jamie and arrange it to look like a suicide—that it had been Jamie driving the car that killed the woman—and he had killed himself out of guilt by throwing his dead body off a seaside cliff. The police believe the story and close the case, and the amoral Hugo gets away with everything as he continues his sordid and unwholesome life undisturbed.

In the New York Times review Diamond Skulls; Aristocracy When It Thinks No One is Looking, Janet Maslin considered that "rarely does a documentary film maker make the transition to fiction as adroitly as Nicholas Broomfield has in Dark Obsession, a psychological thriller displaying a documentarian's fascination for small, telling details." Maslin also praised "an eerie score by Hans Zimmer, a chilling performance by Struan Rodger as Sir Hugo's cold blooded business associate and the unremarked upon inclusion of many odd bits of traditionalism that have presumably made men like Sir Hugo what they are".[5]
