The City and the City: Season 1, Episode 2

1 - 2: 2. Ul Qoma

Borlú encounters another roadblock with his investigation into Mahalia's death when Commissar Gadlem tells him that the case has been taken over by the Ul Qoman Militsya. Gadlem allows Borlú to stay on the case and travel to Ul Qoma, but purely on an advisory capacity: the Ul Qoman Militsya are now leading the investigation.
