Code of Deception — Larry Lavoie

When two OSS agents go missing, President Roosevelt once again calls upon his trusted aide, Gaston Carson. The search takes Gaston to Santa Fe, New Mexico where he lands in a hotbed of frantic activity surrounding a top secret project in a remote area outside of town. Gaston soon discovers the people he is tracking down are involved in domestic spying surrounding the Manhattan Project and the development of the atomic bomb. Santa Fe is the center of international spy activity and Gaston learns he cannot trust anyone, even those he is working with. When President Roosevelt suddenly dies, Gaston is left with no connection to the White House and no one in the Government he can trust. When his wife and child are threatened by an unknown enemy, he must find a way to save his family and prevent the enemy from destroying the atomic bomb before it is even tested. This is book four of the Code Series featuring Gaston Carson throughout the war years.
