From IMDB:

British police drama that revolves around two mismatched detectives who scour London solving complex cases.

From Amazon Prime:

Despite their polar opposite personalities, methodical DI Susan Alembic (Amanda Donohoe) and unorthodox DS Luke Stone (Kris Marshall) work as an effective team solving complex crimes.

From Amazon Prime you can stream two seasons of this series. Season 1 consists of 6 episodes while season 2 has only 4 episodes. Each episode lasts about 1 hour and 10 minutes.

DI Alembic is procedure oriented while DS Stone is intuitive, somewhat eccentric, and really smart. They both appreciate each other even though they constantly tease each other. Eventually Stone comes off as a loner who feels intensely the harm done by peoples’ evil actions.  He is often insulted by DCI Turner (Tim Woodward) but holds his tongue because Turner is his arrogant and nasty boss.

Clever plots and the interplay of characters make this series an acceptable watch.
