During a tour of her future home-the house in Grosvenor Square-Ariana makes plans to redecorate according to her tastes. But when Philip arrives home later, he is informed that an expensive silver candlestick and a miniature portrait of George III have gone missing. Moreover, each time Ariana visits the house, accompanied by a friend or relation, another item disappears.
Shortly thereafter Ariana is abducted as she leaves a performance at Covent Garden Theatre, leaving Philip to unravel the pieces of the mystery. Where has his future bride been taken, and by whom? For what reason? How does Ariana's faith play a role?
