"X-Men" star Rebecca Romijn and "The Closer" vet John Tenney will star in a new TNT private-eye series based on author David Baldacci's Sean King and Michelle Maxwell characters, the network said Tuesday.

The as-yet-untitled series, which has been given a 10-episode order, will revolve around a pair of unorthodox private detectives and former Secret Service agents who use their unique skills to solve crimes.

Maxwell (Romijn) is a formidable investigator with athletic prowess and Beltway connections who's determined to prove herself after being forced to resign from the Secret Service. King (played by Tenney), meanwhile, is a recovering alcoholic who was bounced from the Service after a candidate he was protecting was assassinated. Now a lawyer, he uses his legal insight to solve cases.

Michael O'Keefe and Chris Butler also star in the series, which is being produced by CBS Television Studios for summer 2013 premiere.

Shane Brennan ("NCIS") wrote the pilot, with "Third Watch" alum Grant Anderson executive-producing along with Brennan.

Baldacci will serve as a consultant on the series.
