Professor Zamorra becomes embroiled in a new case: Sara Moon, the servant of the Guardian of the Scales of Destiny, asks him to track down a magical fan in Hong Kong. This fan is said to grant her access to Hell. However, Zamorra and Nicole are skeptical. Just recently, brutal ritual murders were committed in Hong Kong, indicating demonic activities. Is this merely a coincidence, or is there a connection? As evil forces gather over the city, Zamorra must summon all his strength to avert the looming danger in time. But will he be able to face the battle alone? In the audio play version by Uwe Voehl, based on a novel by Susanne Picard.
