Largely on the court-and-spark teamwork of stars Nathan Fillion and Stana Katic, this ABC mystery series became enough of a success to merit the sophomore round it's about to begin.

Fillion plays mystery writer Richard Castle, who decides to base his new stories on the New York police detective (Katic) he helps solve a murder case.

Susan Sullivan ("Falcon Crest") is a standout in the supporting cast as Castle's ex-stage-star mother. *** (Not rated: AS, P, V)
