Once upon a time there was a Tsar named Berendei, and he had three sons, the youngest of whom was called Ivan. Now the Tsar had a beautiful garden with an apple-tree in it that bore golden apples. One day the Tsar found that somebody was visiting his garden and stealing his golden apples. The Tsar was very unhappy about this. He sent watchmen into the garden, but they were unable to catch the thief.
