Nikolai Spasky (1982-1991) never appears in the 39 Clues book series, having passed away much before the events of the first book, but is often referenced in the thoughts of his mother, Irina Spasky, especially in Book 6. His father was Nikilovana Spasky, the best friend of a former Lucian leader named Ruslan Radova. He was killed, though, by Isabel and Vikram, for he was supposed to be the leader of the Lucian branch. Further information about Nikolai Spasky's life is unknown. In Irina's will, she leaves everything to Nikolai, but after his death, she changes the will to leave everything to the St. Petersburg Children's Theatre that brought him such joy.
