La grande menace

A 1948 film noir/police procedural. We're in the midst of the Cold War & American agents are on the hunt for Communist operatives which sets the scene as one of ours sees a wanted agent at a sporting event only to be gunned down (shocking for the time I would imagine as we see blood spatter across the man's face) by Raymond Burr (sporting a very Leninesque goatee). Enter the lead FBI agent, played by Dennis O'Keefe, who tracks the spotted man to San Francisco only to find the man murdered in his room even though the FBI were all over him. When they scour their surveillance footage they come up w/another enemy agent, disguised as a priest (which raised no flags), who spends his days in his apartment painting canvases which O'Keefe figures is the means of transporting information. Enter Louis Hayward, a Scotland Yard agent working the same case from the European side of things & he teams up w/O'Keefe to track down the cabal of enemy agents (the info in question is coming from a scientific collective on the cusp of a breakthrough) when they figure out hidden formulas are embedded on the paintings themselves, they figure one of the group is leaking the info. Very procedural in the extreme (I wouldn't be surprised if some would viewers will drop in the ubiquitous "dun dun" from Law & Order as each scene cuts into the next) but immensely engrossing, keeping you on the edge of your seat w/a satisfying gunfight taking place in a darkened home festooned w/Russia's best trying to win the day.
