As fireflies dazzle like tiny glowing lanterns, tea maven Theodosia hosts an elegant evening tea on the patio of the Tangled Rose B and B. But in this gentle darkness an intruder has made their way in and slipped deadly drugs into the baked Alaska of Mrs. Van Courtland, one of Charleston's local grande dames. Shocked by this brazen act, urged on by Mrs. V's grieving son, Theodosia begins her own shadow investigation.

Soon, she finds herself at odds with a greedy developer, the questionable residents of Honey Badger House, a vengeful ex-daughter-in-law, ne'er do well relatives, and a housekeeper who knows all the secrets.

As Theodosia hosts a Moulin Rouge Tea and a Queen Victoria Tea, her tea sommelier Drayton is assaulted by a masked stranger and the fiancé of Mrs. V's son is kidnapped. It's only at the Starry Starry Night black tie ball that Theodosia stumbles upon the killer and gets pulled into a dramatic life and death chase.
