Dirk Bogarde was a marvelous actor, and this is a fine film. But if you insist on believable stories, you won't like it. It's as true to life as an Agatha Christie story, and just as entertaining.
The plot is this: An English lord and a penniless scoundrel who looks exactly like him are in the same POW camp during World War II. Years later, another veteran claims the scoundrel actually killed the aristocrat and has been impersonating him ever since. The whole thing winds up in court, putting the aristocrat's wife through some agonizing moments. Finally, when nobody can stand the suspense any longer, the truth is revealed.
The idea of someone meeting his exact double is as silly as it is unbelievable, and by the 1950s there were ways to verify whether a living man was the war veteran he claimed to be. So you can't take this seriously. But if you suspend disbelief, you will really enjoy it. Though it's not marketed as a mystery, it's ideal for mystery fans.
