The film takes place in the English countryside at the cottage of a somewhat wealthy old woman named Mrs. Bramson (Whitty), an invalid who lives there with her niece Olivia (Russell) who also happens to be employed by the dowager. For some reason Bramson is cranky and verbally abusive towards Olivia. So of course Olivia resents the old woman's attitude and feels trapped and bored with her position so she acts less than kindly towards her.
As the story begins police and some of the townsfolk are executing a search for a missing local woman. It's a small community so word of the disappearance as well as gossip about the woman travels quickly.
Mrs. Bramson discovers that someone has attempted to hide some pieces of broken china in one of her flowerbeds. She soon realizes that it was her maid Dora (Tottenham) that was responsible and confronts her about it. The maid explains that she hasn't been herself since meeting her new boyfriend, who she plans to marry but can't get him to actually commit to a date. Dora asks Bramson if she could speak to him on her behalf and the old woman acknowledges that she'll " deal with him ".
The rest of the film is very suspenseful as Danny waits for an opportunity to gain access to the old woman's safe and steal her money, and Olivia is first repulsed by, then finds herself becoming strangely attracted to the charming rogue. All the while trying to determine whether he is responsible for, or even capable of committing the recent murder. Time after time our attention is drawn back to the mysterious hatbox and its possible grisly contents.
Montgomery is very convincing as the smooth-talking, disturbed, pathological liar Danny and as the story progresses we discover more and more about the character's background. I felt kind of bad for Olivia as she slowly but surely gets lured out of her shell by Danny's charm and almost poetic ramblings and finds herself drifting away from her boring, rich boyfriend Justin (Marshal) towards Danny even though she's knows how potentially dangerous he is. She just seems to be totally bored with her life as it is and just craves some excitement. There's a great scene that takes place in the kitchen when the two happen to meet up in the middle of the night. You can feel the chemistry between the two characters and the scene will bring you to the edge of your seat.
Whitty dominates every scene that she's in. The ending is almost unbearable when she finds herself alone and vulnerable after seemingly having total control over everyone for the majority of the film. There's also some pretty good dark humor courtesy of the cook (Harrison) that helps to lighten up the mood a bit now and then. The sets are very nicely designed and very detailed, especially the rooms in the cottage where most of the film takes place.
If you're a Hitchcock fan you'll probably enjoy this film. There's not much action. but there are extra helpings of tension and suspense to go around.
