Baroness Emma Magdolna Rozália Mária Jozefa Borbála "Emmuska" Orczy de Orczi (23 September 1865 - 12 November 1947) was a Hungarian-born British novelist, playwright and artist of noble origin. She is most known for her series of novels featuring the Scarlet Pimpernel. This is one of her novels.

The Emperor's Candlesticks is a historical novel by Baroness Orczy. Written soon after the birth of her son John, it is her first book as an author rather than translator and was a commercial failure. As in the Scarlet Pimpernel, the theme is international intrigue, but this time the setting is pre-World War One Europe and Russia rather than Revolutionary France. When a group of Russian anarchists kidnap a Russian prince in Vienna there are repercussions. On learning that the Cardinal d'Orsay has agreed to convey some hollow candlesticks from the Emperor to the Princess Marionoff in St Petersburg, two spies both see the possibility of using them to convey messages safely into Russia. One is an eager young idealist involved in the plot against the prince, the other is Madame Demidoff, a beautiful agent of the Tsar. When the candlesticks go missing at the border, the two engage in a race to get them back, both realizing that their very lives could depend on the retrieval.
