Castle: 4x16
Linchpin (2)
Castle & Beckett race to find the “Linchpin” in order to stop the first domino in a chain of events which will plunge the United States into war. Their efforts continue to put Castle in contact with Sophia Conrad – a smart, commanding and sexy CIA operative who was Castle’s inspiration for Clara Strike in the “Derrick Storm” series of books; and intelligence officer Martin Danberg is back.
