The byline used by Emma Magdalena Rosalia Maria Josefa Barbara Orczy (1865-1947) was Baroness Orczy. Orczy was born in Tarna-Ors, Hungary, the only daughter of Baron Felix Orczy, a noted composer and conductor, and his wife, Emma. Orczy moved with her parents from Budapest to Brussels to Paris and then to London, where she learned to speak English at the age of fifteen. She was educated at West London School of Art. Orcy's first detective stories appeared in magazines, but as a writer, she gained fame in 1903 with the stage version of The Scarlet Pimpernel. In the late 1910s, Orcy and her husband moved to Monte Carlo, where they stayed during the Nazi occupation. Her husband died in 1943, and after World War II, she spent her remaining years in England.
