This British drama directed by Jacques Tourneur threw me for a loop: for over an hour the story written by Philip MacDonald meandered, resembling the traditional shaggy-dog story, a type of movie I detest. Postponing getting to the point, with loads of tangents instead of an involving adventure.
It is initially structured just like my favorite British movie, Mike Hodges' "Get Carter", which I attended several times in 1971 when it came out, so enthralled with its style and detail. Here we have Ray Milland with a tough-guy accent/vocal delivery, travelling to UK in search of the real story behind his younger brother's death as a commando in World War II. He doggedly pursues the facts, but is repeatedly stonewalled as he approaches and interviews the fellow surviving members of his brother's squad.
Meanwhile, a romance develops between him and Patricia Roc, girlfriend of a Scottish officer he questions, replete with a "meet-cute" scene in which Roc literally accidentally bowls Ray over (physically) when they meet for the first time. The motif of him repeatedly late or standing her up for dates while he goes on his important search for answers about his bro underscores the shaggy-dog aspect of the storytelling.
Finally, in the last reel or so the movie comes to a head, with the revelation of who killed bro and why, and in a rather moving and unexpected fashion, British civility and honor creates a nonviolent and most satisfying ending.
Quite offbeat in its treatment of the thriller genre, it's another example of Tourneur's skill.
