Yerofeyev also claimed to have written in 1972 a novel Shostakovich about the famous Russian composer Dmitri Shostakovich, but the manuscript was allegedly stolen in a train. The novel has never been found. Before his death of throat cancer Yerofeyev finished a play called Walpurgisnacht, or the Steps of the Commander ("Вальпургиева ночь или Шаги командора") and was working on another play about Fanny Kaplan.
