Der Greifer translates as The Copper -- and, yes, this is a detective yarn. Hero Hans Albers, representing Scotland Yard, mingles with the cream of British society to bring a murderer to justice. Greeting everyone, friend and foe alike, with the same off-handed cheerfulness, Albers is able to put the culprit "at ease" long enough to tighten the noose. And, of course, he wins the girl, fetchingly played by Charlotte Susa. As often happened in German films of this period, the depiction of British aristocrats in Der Greifer is too broad and stereotyped to be believable -- though to be fair, German characters were treated in much the same manner in British films.
