BFTV has a new interview with Gail O'Grady, who guest stars on tonight's episode of Castle.
The TV veteran, who most recently played Wanda Perkins on The CW’s cheerleading comedy-drama Hellcats, appears on Castle as a reality TV star named Margo Cowan – one of the members of a Real Housewives-esque show called “Wives of Wall Street.” When one of the other ladies is murdered, Beckett and Castle are called in to investigate the crime.
