About the Show

Richard Castle (Nathan Fillion) - was a famous mystery novelist and divorced father raising his teenage daughter (Molly Quinn as Alexis), while being kept grounded by his Broadway diva mother (Susan Sullivan as Martha Rodgers) and bored with his own success. He then found out that a real-world killer was staging murder scenes depicted in his novels. Castle was questioned by NYPD Detective Kate Beckett (Stana Katic), a bright and aggressive detective who kept her investigations under tight reins, especially the years-old unsolved murder of her own mother. Though they instantly clashed, sparks of another sort began to fly, leading both to danger and a hint of romance as Castle stepped in to help find the copycat killer.

Also starring in the series are Ruben Santiago-Hudson as NYPD Captain Roy Montgomery, Tamala Jones as Medical Examiner Lanie Parish, Jon Huertas as NYPD Detective Javier Esposito and Seamus Dever as NYPD Detective Kevin Ryan.
