According to the polls, it's only a matter of time - and not that long a time - before the United States elects its first female president. Which will make her husband - what? Well, if he's the ex-cop who solved the murder of the president's first husband and brought the killers to justice ... and if he's not the kind of guy to stand on formality ... and if he doesn't want to be the head of the FBI ... and if he takes out a license and becomes the first private eye to live in the White House ... That would make him The President's Henchman. Jim McGill's first case is to find out who is stalking a member of the White House press corps, before that stalker turns the tables on McGill and maybe even threatens the president herself. He also has to be a shadow advisor to a young Air Force investigator who is looking into a he-said she-said charge of adultery leveled against a female colonel working at the Pentagon, a case with the potential to derail the new president's administration before it has a chance to begin.
