I’m pleased to bring you a few more spoilery scenes from the highly anticipated February 6th installment of Castle, “The Blue Butterfly”. The CTV promo below features Castle and Beckett, who are investigating the murder of a treasure hunter. The dynamic duo discover the case is linked to a mysterious homicide from 1947 involving a hard-boiled private detective. Castle realizes the only way to solve the present-day murder is to solve the murder from the past. Fans will see the 1947 case come to life through stylized flashbacks, featuring Castle as the private eye and Beckett as a femme fatale.
