Alan Ladd stars in The Treasure of Hang Li, a Box 13 mystery that begins with an unusual shopping errand. A letter sends the writer-adventurer to a curio shop, where the object he has been asked to collect comes with questions instead of a price.

The jade draws competing interests around Dan, turning a simple request into a dangerous search for answers. Listen as an apparently small object becomes the centre of a much larger mystery.

This stand-alone story suits listeners who enjoy antique-shop intrigue, enigmatic clues and classic radio adventures built around an irresistible invitation. Dan wanted material for a story, but the consequences are his to face.
