This book, unexpected for herself and for her readers, was written by Marietta Chudakova, a famous historian of Russian literature of the twentieth century, a world-famous biographer and connoisseur of the work of Mikhail Bulgakov. A fascinating, action-packed story about the dangerous adventures of a young heroine and her faithful friends - Vanya-opera, Tom Murphy, Skin, Fursik and many others - begins in the first novel of the trilogy, “The Mystery of the Death of Angelica”, continues in the second - “Portrait of an Unknown Woman in White” and ends in the third - “The Testament of Lieutenant Zayonchkovsky.” Real Russia of our days, real risk, real dangers, the most real villainy and the most genuine selflessness, courage and nobility - this is what attracts both eight-year-old and sixteen-year-old readers to these books... 2nd edition , corrected.
