text: This interesting film noir features three very good performances: Sanders, Patrick, and Blackmer. The scenes between Sanders and Patrick are particularly outstanding. Demming, as the detective, is unfortunately not nearly as good. He lacks the intelligence, strength, and cynical world view of a Bogart. Had Humphrey played this part, we could have had a classic.<br /><br />Pace, location (a library), and atmosphere are all good. But there are a few plot holes. Sanders strongly fears Blackmer and the ruthless organization (Nazis) he represents. Yet after mistakenly killing Blackmer, Sanders seems to experience no anxiety or remorse. Sanders then seizes the library and its occupants by using the ruse that he and his men are detectives investigating the murder. However, Sanders' hit man later tries to kill Demming by shooting him (without a silencer), even though the many other detainees could have been expected to hear, and become alarmed by, the noise. Finally, Sanders' hit man tries to kill Roberts, who has discovered the truth, but when she faints, he inexplicably does not. <br /><br />What bothered me the most, however, was that the chance for a great and unexpected conclusion was wasted. Throughout the film Patrick is portrayed as a smart, hard-as-nails sociopath fearing nothing. Yet at the end, she flees panic-stricken from the last surviving Nazi, a brutish thug. By the time the cops find him, he has killed her. And she ends up being just another weak, stereotypical victim. What should have happened is this: the cops find the Nazi thug, but he is dead. She has cleverly killed him, and then vanished -- to continue her evil ways.
