Summary: There was a mystery in the New Mouse City's Egyptian Mouseum! The Black Papyrus, an ancient document that reveals the secret of eternal youth, had disappeared. The mouseum's director asked me to help him find it. Luckily, a secret agent came to our aid ... but could we trust him? It was up to us to recover the precious scroll! (Back cover)
