If you like Ken Stott in Rebus, you'll like this earlier effort. The subject matter is pretty seamy, particularly for American TV audiences, which is probably why it never made it to PBS or A&E. It does have a little of "The Wire" feel to it, but it's clearly Ken Stott's vehicle as DI Pat Chapel. Stott plays Chapel like a younger Rebus who still feels a certain degree of devotion to the job and not just to the crime at hand. But, like Rebus, Chapel is a flawed character constantly flirting with on the job disasters, mostly of his own making. His subordinates are affected by the nature of the work and his less than stellar management style, but in the end they catch the bad guys.
The series has a few unusual twists and turns with one of the stars coming to an early end in Season 2 which, apparently, is all we're allowed to see of the generally excellent series. The show ran for 5 years on British TV, but so far only the first two seasons have been released on DVD. Since the show originally ran starting in 1998-99 I don't hold out a lot of hope for the balance of the episodes. Again, the subject matter is rough with all the expected violence and nudity, but the acting and scripts are first rate. Just don't expect "Midsomer Murders".
