Berlin 1946: Inspector Oppenheimer uses his trained sense of smell in the service of searching for missing persons.

When the disfigured corpse of a "German diaspora" refugee is discovered, Oppenheimer receives orders from Colonel Axakov to take on the case.

The fourth case of Inspector Oppenheimer.
