It has been significantly more than a month since the last new episode of "CSI: NY" aired and, in fact, it has been nearly a month since any episode of the show, new or old, has been on CBS. Well folks, that is going to change tonight -- "CSI: NY" is coming back with an all-new episode. Or, an episode that is new except for the basic plot which will have someone (one truly has to assume) die and the investigators work out just whodunit and why they done did it and then get those who are guilty. This is a procedural after all, they do have to go by the rules for procedurals. The joy, as it were, is in the chase.
