It's that time of the year again for Castle.
Fresh off an incredibly fun trip back to 1947, the ABC hit will air the first of its annual two-parter next week, bringing on board Jennifer Beals as a CIA agent - who also has a past with a certain crime-obsessed author.
Look for Beals' Sophia Conrad to assist Castle and Beckett when their murder case leads into a grand, international conspiracy. Also, look for Josh Stamberg to guest star as an intelligence officer... and for Beckett to get a bit perturbed as Castle's interaction with this beautiful new woman. Watch the first official trailer now:
