June Lansdowne (Lilli Palmer) receives a mysterious letter and a key. Upon investigation, June is told that the key is one of seven keys, meant for a door with seven locks. After a murder and a disappearance, June enlists the help of the police.
This is when an astonishing discovery is made, and June's adventure truly begins. Along the way she meets a group of suspicious characters, including Dr. Manetta (Leslie Banks), whose hobby is collecting instruments of torture for his "enhanced interrogation" room.
CHAMBER OF HORRORS is a well-constructed mystery / thriller. Banks is supremely, sublimely wicked in his role, complete with a cape and pet monkey! He sort of reprises his old Zaroff character from THE MOST DANGEROUS GAME, infusing him with even more menace and insanity!
Ms. Palmer plays Lilli as someone with guts and brains. She's certainly not a pushover!
A classic movie for lovers of Edgar Wallace-inspired suspense...
