Natalie Black, the U.S. ambassador to the Court of St. James, has returned to Washington, her job in jeopardy. Her fiancé, George McCallum, Viscount Lockenby, has died in a car accident, and mysterious rumors begin that she’s responsible begin to surface: she broke off the engagement and, heartbroken, he killed himself. Then someone tries to force her off the M-2 outside London. Again, rumors claim it was a sympathy ploy. When she returns to the United States, she’s nearly killed when a car tries to mow her down while she’s out for a run.
