This was one of my favorite "Mystery!" series. This was something of a precursor to shows like "CSI" and "Without a Trace," and ten times better. Robson Greene is DI Dave Creegan, a workaholic who works in a fictional British unit called Organized Serial Crime (OSC). Creegan received a bullet in the head some time back, and was brought back to life through the miracle of medicine, now walking a tightrope on the edge of sanity as the semi-suicidal detective hunts down serial killers and other perps through his gift for thinking like they do. Creegan's partner, DI Susan Taylor, is a no-nonsense type whose method for solving cases is quite the opposite of Creegans. DC Mark Rivers, also a key player, is as far removed from Creegan as possible, a by-the-book detective who is just as content to wait for back-up as jump into the fire. There were some excellent shows, but the first season is by far the best, starting off with a perverted and villainous suspect portrayed by Ian McDiarmid, of "Star Wars" fame.
Perhaps this show lacks some of the class that made earlier shows such as "Prime Suspect" such a treat, but the only thing on "Mystery!" to match it as of yet is probably the most recent American-produced Tony Hillerman adaptations.
