You might like Burn Notice, depending on your tolerance for network television tropes of the mid-aughts. It’s a “monster of the week” format, rather than the serialized approach of Reacher, but it typically includes a scene or two referencing the season arc in any given episode, so you still feel like the narrative is advancing, even if the majority of the episode was a side quest.

The gist is that a US government spy gets “burned” and turned loose in Miami. He, and the few contacts he has who will still speak with him (which include his mother, an ex-gf with a bombastic personality, and Bruce Campbell at the height of his smarmy powers), attempt to figure out who burned him, while also getting wrapped up in “favors” for various folks about town that inevitably wind up more complicated than was initially let on. Antagonists run the gamut from international terrorists to con artists who target the geriatric (it is, after all, set in Florida).

It’s not high art, but it’s got a winning cast, decent action (for network television), and, on occasion, I think some pretty clever solutions for problems which leverage the “spycraft” gimmick. Worth a shot.
