The photo below inspires ... reverie.
Scenario for novel: A former First Lady passes. The post-funeral reception is held in the famous home which at the time was still owned by the widow of her assassinated husband's assassinated brother. There, then-current First Lady Killery Hinten and her husband, President Tom Essent Hinten, pull aside a member of the "royal family" -- who happens to be a sitting member of Congress -- and, in the privacy of a butler's pantry, tell him who "really" ordered the murder of his presidential uncle. Some seven years or so later, in an interview (one that seems to have disappeared from the Internet) published by his state's only major daily newspaper, the congressman reports that "Castro" did it.
Never again does he publicly raise the topic.
