Castle TV Series, Seamus Dever as Kevin Ryan
Kevin Ryan is a NYPD homicide detective, who works as part of Kate Beckett’s team. He and his friend Javier Esposito regularly tease Beckett, but they are also protective of her. (Ryan’s character was a late addition to the show).
After a serial killer imitates the plots of his novels, successful mystery novelist Richard Castle (Nathan Fillion) gets permission from the Mayor of New York City to tag along with Detective Kate Beckett (Stana Katic) and an NYPD homicide investigation team for research purposes.
