This episode just might be the best CI episode that Chris Noth ever did during the show's run. Noth and Julianne Nicholson get the case when a gossip columnist is killed when a car bomb is planted in his vehicle. Just the nature of the kill tells you there's some kind of professional involvement.
The very nature of the victim's work guarantees an array of suspects and Noth and Nicholson have to plow through a list of people in all walks of life. It's one of the most complicated paths to an arrest.
I will say that the individual involved is one of the most arrogant ever portrayed on a Law And Order franchise show. The final confrontation and arrest with Noth is beautifully handled.
Don't miss this one. By the way elements of one of my favorite films Sweet Smell Of Success are included in the plot so much so that Chris Noth even refers to the film.
