Season 6
When viewers first met Richard Castle - a famous mystery novelist and divorced father raising his teenage daughter, while being kept grounded by his Broadway diva mother - he was creatively blocked.
But when the NYPD questioned him in connection with a series of murders staged to imitate crime scenes from his books, Castle found inspiration in Kate Beckett, a bright and aggressive NYPD homicide detective with a fascination for odd and offbeat cases, stemming from 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.
Once that initial case was solved, Castle and Beckett continued to investigate strange homicides in New York, combining Castle's writer intuition and Beckett's creative detective work.
In Season 5, Castle and Beckett tried to keep their new relationship a secret as they learned the man responsible for Johanna Beckett's murder was the powerful Senator Bracken.
When Alexis was kidnapped, Castle got his daughter back with help from a man he'd never really met — his father. Detective Ryan got the good news that a baby was on the way and Castle received the greatest birthday gift of his life thanks to Beckett's Rear Window-esque surprise in the 100th episode.
The mystery man and his muse hit a crossroads as last season ended with Beckett wrestling over whether to take a high-profile job in DC - a dilemma made more complicated when Castle proposed to her.
Castle and Beckett will deal with the consequences of their decisions against the backdrop of a high-stakes investigation when Castle returns for Season 6.
Castle stars Nathan Fillion as Richard Castle, Stana Katic as NYPD Detective Kate Beckett, Susan Sullivan as Martha Rodgers, Molly Quinn as Alexis Castle, Penny Johnson Jerald as NYPD Captain Victoria Gates, Tamala Jones as Medical Examiner Lanie Parish, Jon Huertas as NYPD Detective Javier Esposito, and Seamus Dever as NYPD Detective Kevin Ryan.
