Watch King & Maxwell Online. Tenney is King and Romijn is Maxwell, partners in private investigation who also share a nonsynchronous story with the Secret Service, which each left after something bad happened to a person they were assigned to protect. Still based in Washington, D.C., they have been working together a year when we meet them; the circumstances of their own meeting are not described, though they are possibly known to the readers of the books, by David Baldacci, upon which the series is based.
