by M.M. Kaye, 1955
Miranda Brand goes to Berlin with cousin and his wife, Stella. Soon is involved in murder of Brigadier Brindley, who told story of stolen diamonds. Then the governess is murdered. Turns out it was Stella – she was going to murder Miranda – jealousy and wanted money. Miranda and Simon Lang, the detective, end up in love and married at the end.
Not M.M. Kaye’s best mystery. Still need to read “Death in Kenya” and “Shadow of the Moon.”
