"On her first trip to Washington, D.C., Elena Standish finally gets to visit her American mother’s wealthy parents and their magnificent home. Elena’s grandparents are marking a milestone anniversary by throwing an elaborate party with the influential friends of her grandfather, a prominent political industrialist. Even President and First Lady Franklin and Eleanor Roosevelt are there, and Elena takes pride in capturing the illustrious guests on camera. But the festivities come to a sudden and tragic end when one of the guests, Lila Worth, is run over by a car in the driveway outside. Elena believes Lila was trying to tell her something before her death, and when a call from her employer back home, MI6, confirms that Lila was a British spy, Elena pairs with a fellow agent to find out what vital information the young woman had in her possession."
