Marjery Louise Ellingham is an English writer belonging to the “golden age of English literature,” recognized as the “Queen of Detective Fiction” alongside Agatha Christie, Dorothy Sayers, and Ngaio Marsh. She stood out among other authors of this genre; as Agatha Christie put it, “like a burning lamp.”
At a lavish country house at a reception, a valuable collection of antiques is stolen. Judging by the handwriting, the job is the work of a professional thief—yet not a single suspicious character has been spotted among the noble guests! How did the culprit manage to enter the house without raising any alarm and then slip away with the loot? He probably would have gotten away with it—if Albert Campion hadn’t happened to find a golden women’s ring on a country road.
