Red Swan / P.T. Deutermann.

Enhanced descriptions from Syndetics:

Written with the authority of twenty-six years of military and government service at sea and in Washington, P.T. Deutermann's Red Swan is a brilliant, provocative thriller about the contemporary war that no one sees, but which will shape the future of America and China.

Set in contemporary Washington D.C., Red Swan begins with an ominous phone call from Carson McGill, the Deputy Director of Operations in the CIA, to retired CIA officer Preston Allender. Henry Wallace is dead. A behind-the-scenes operator at the CIA, Wallace was integral to the Agency's secret war against China's national intelligence service, which infiltrates government and military offices, major businesses, and systems crucial to our security. Wallace had severely damaged China's Washington spy ring with a devastating ruse, a so-called "black swan," in which a deep-undercover female agent targeted and destroyed a key Chinese official. Now, Wallace's mysterious death suggests that the CIA itself has been compromised and that China has someone inside the Agency.

But as Allender quietly investigates, he makes a shocking discovery that will upend the entire American intelligence apparatus. For Wallace's black swan operation may have been turned against the CIA; a Red Swan is flying and the question is: who is she, what is her target, and where will she land?
