A birthday surprise - then Venus vanishes. But how and where? And who are the mysterious Tun-Ju and Mrs. Kite? Tarot is alarmed, but why?

It's a dead end for Tarot and Lulli, but "gas man" Sam tracks art-shark Tun-Ju and discovers a very unpleasant kind of magic.

Ozzie the Owl squawks and Sam begins to get his memory back. Later, Tarot, Sam and Lulli visit Tun-Ju, the emperor of art-thieves and it's fun and games all round. But what is the ominous Tun-Ju really after?
