"Truman's novels of Washington will continue to entertain both mystery and Washington buffs." —Washington Post
An international art scandal turns deadly in this fourth book in Margaret Truman's nationally bestselling Capital Crimes series 
Dr. Lewis Tunney, a brilliant historian who had stumbled onto an international art scandal, was brutally murdered in front of two hundred guests at an elegant party at the Smithsonian. When his fiancée, Heather McBean, flies in from Scotland to learn more, Mac Hanrahan, the captain in charge of the case, takes a heated interest in her.
And when two more murders are committed, Hanrahan has reason to worry about Heather's sleuthing. But Heather is stubborn and insists on going her own way—right into the arms of a killer . . .
