The Paradise of Thieves is the thirteenth episode of the third season of Father Brown.
A dead man is found in a bank vault locked from the inside, and Father Brown must work fast to solve the mystery in order to save an innocent man from paying the ultimate price.
Tropes:
- Human Mail: The murderer gained access to the bank vault by having himself shipped in inside a crate supposedly containing pieces of art.
- Locked in a Freezer: Father Brown and Sid get locked in a bank vault and are in danger of suffocating. In working out how to escape, Father Brown also works out the solution to the mystery.
- Locked Room Mystery: After the Victim of the Week is found, suspicion naturally falls upon the only person with keys to the vault. Father Brown believes him to be innocent and sets up to discover how this seemingly impossible crime could have been committed. Sure enough, it turns out that the true villain arranged for accomplices to smuggle him into the vault ahead of time in a package that his intended victim was expecting (and thus didn't find suspicious), killed him, and then broke out.
