Here is the link to the extra pieces available from the Oxford University series Piano Time book 2.
The piece on page 2 looks rather complicated; but if you look carefully, you will see that you only play the very top line; someone else has to find their way through the other notes! Using the high notes, play CDE with your left hand, and the next three black notes with your right hand, softly and spookily, as fast or as slow as you like, and hold the right pedal down all the time each time you play your notes.
Listen carefully in during the rests, and follow the dynamics (louds and softs) carefully. Use your imagination to paint a picture!
