Andronnikov is a Russian man working for the Zemblan extremists, and he is Niagarin’s partner. Andronnikov and Niagarin are hired by the Zemblan extremists to find the crown jewels. They ransack the entire palace but do not find anything (the novel implies that this is because the jewels aren’t in the palace at all). Andronnikov and Niagarin are also hired to break into Queen Disa’s villa on the French Riviera and they steal some paperwork that reveals King Charles’s whereabouts in America, which ultimately points Gradus to New Wye. Andronnikov is tall and handsome and Kinbote insists that he is a lovely man.
