From IMDB:

DI John Rebus is a hard drinking, unkempt, womanizing police officer whose job is his whole life. He is the most senior and most experienced DI at his station. He has a mysterious past that his partner DS Siobhan Clarke learns about from time to time through various comments Rebus makes. She is a young woman who wants to succeed, but does not have much of a personal life. She feels being paired with Rebus jeopardizes her career because of his unorthodox methods, but she is also fascinated by the man and is extremely loyal. DI Rebus’ boss is Chief Superintendent Templar, a woman who was one of Rebus’ lovers in a distant past. Their relationship is now one where they barely tolerate each other.

From Acorn TV:

Based on the novels by Ian Rankin, this gritty crime drama stars Laurence Olivier Award winner Ken Stott (The Hobbit) as gruff Scottish detective John Rebus. The world-weary policeman investigates the grisly crimes that mar Edinburgh’s historic streets in these sharply written and intricately plotted mysteries.

From Acorn TV you can stream seasons 2,3,and 4. Season 1, which is described in IMDB, seems to be missing. Season 2 has 2 episodes. Season 3 has 4 episodes.  Season 4 has 4 episodes. Each episode is a complete story.  Each episodes lasts approximately 68 minutes.

Fans of Ian Rankin should enjoy these well-done adaptations with interesting and compelling plots.  Only one, season 4 episode 1 (Resurrection Men)  stands out as especially violent.

Beautiful Claire Price plays Rebus’ long-suffering partner, DS Siobhan Clarke (which is pronounced “sha-von”.) Jennifer Black plays DCS Gill Templer.

As is common in many detective stories, Rebus is a heavy smoking quasi alcoholic.  In all fairness, however, people as portrayed in the British isles and in my own experience drink A LOT of alcohol. In one of the more recent Ian Rankin novels, Rebus’ unhealthy lifestyle catches up with him.
