Castle Season 6 Episode 4 “Number One Fan” Images

We’ve got some first look images from Castle’s October 14th (season 6 episode 4) “Number One Fan” to share with you below.

The episode is set to see Castle meeting his most ardent fan – from behind the barrel of a gun. It seems murder suspect Emma Briggs  (guest star Alicia Lagano) is so desperate to prove her innocence that she has taken a group of people hostage at gunpoint, and will only negotiate with Castle.

Billy Miller (“The Young and the Restless”) also guest stars as Mickey Gerhardt, a hot headed Wall Street banker who gets caught in the hostage situation.

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.

Guest Cast: Alicia Lagano as Emma Briggs, Billy Miller as Mickey Gerhardt.

“Number One Fan” was written by Terence Paul Winter and directed by John Terlesky.
