A brilliant story with a fast and pregnant dialogue all along, presents the fascinating case of a double-faced woman, the other face of which is well hidden behind a mask of superb charm and beauty - it's impossible to believe anything else but the best of her; but a nosy insurance investigator, not at all sympathetic but rather callous and rude in his constant meddling into the business of a happily and recently married couple, finds out more and more unpleasant things no one really wants to know, not even himself. Alas, it all leads to more unpleasantness.
Margaret Lockwood is as usual quite reliable and convincing in not a too glamorous part, Ian Hunter makes the perfect husband and reacts as anyone would in such an awkward situation, intrepidly handling the crisis with an admirable effort at controlling himself, while Barry K. Barnes carries through the difficult task of making a graceless character acceptable for his uneasy plight. Anne Crawford is a delightful surprise as another beauty, who after all remains when all the lights are gone. This is not clearly expressed in the film, but it should not be forgotten.
To this comes the interesting detail of the black pearl, which somehow symbolizes the whole story. She wants to get rid of it but refuses to sell it for a fortune, when asked for it she denies she still has it, and then it returns to bring about her doom. It should be noted that the author also was guilty of "Laura".
It's not a great or ambitious film but well above the average of so many other similar secondary melodramas.
