When does a little black dress become a lethal black dress? When it becomes unexpectedly weaponized at the most security-conscious event in Washington, D.C.—the fabled White House Correspondents’ Dinner.

Fashion reporter Lacey Smithsonian is delighted to finally take her place at the legendary D.C. insider bash, but she senses something is amiss with a pushy TV reporter's vintage Madame X gown with its stunning emerald lining. When the woman takes a tumble with a tray of champagne and dies of something other than embarrassment, Lacey taps into her ExtraFashionary Perception and follows her hunch that this was no freak accident.

Juggling her investigation with her love life and future in-laws complicates matters, while spies and lies and an enemy close to home bring Lacey face to face with danger and jealousy, the green-eyed monster. But this time, will the style sleuth discover that green is also the color of death?
