Extremely interesting and absorbing drama that generates tension and suspense about what actions the intelligent, civilized, international banker Claude Raines will take as clues filter in about the restlessness of his younger wife. Some of the most effective scenes are those of smouldering volcano Raines, particularly a delicious scene where Raines is on the patio in Swtzerland dictating a high level letter about investment risks while fiddling with a pair of new binoculars. His dictation trails off as he intermittently praises the amazing detail the binoculars provide and sweeps them in ever widening arcs across the lake. Then he returns to the dictation, puts the glasses down, can't resist picking them up again, resuming and interrupting the dictation repeatedly while we squirm in our seats knowing that any second the binoculars will alight on Ann Todd and Trevor Howard returning by motorboat from an innocent, clandestine, all day cable car ride up the Swiss mountain, whiich Raines will misinterpret. The scene is exquisitely handled in all respects, with superb dissection of every conceivable possibility for tension and suspense building. This scene is an extremely accomplished achievement of cinema accomplishment, with an intricate unfolding of micro-events that are unforgettable, employing just a dictation setting at a table on a patio, the efficient secretary taking shorthand and a pair of binoculars. This is CINEMA first and foremost, with David Lean not tempted to reduce it to a standard adultery-suspicion formula and all actors rise to this higher purpose. There are some clumsy flashbacks and the sound is so faint one needs headphones to reduce listening strain, but the print is of pristine quality and, overall, it's a rare treat. There are easy to read subtitles to compensate for the faint sound.
