Theodosia and Drayton are catering a formal tea at a hot-air balloon rally. Suddenly, a strange drone zooms out of nowhere and crashes into one of the balloons, killing all three of its passengers. Theodosia learns one of the victims is the CEO of local software company SyncSoft, and begins her own investigation into what happened. Was it the CEO’s soon-to-be ex-wife, or his personal assistant? Or Two rival antiques dealers known for dirty dealing? Or was the killer the fiancee of one of Theodosia’s dear friends, who turns out to be an employee and whistle-blower at SyncSoft?
