Alfie helps a mysterious boy who appears from nowhere and is obviously in trouble. But his sympathy is short-lived when he finds that the boy has stolen his jacket and vanished. Then Alfie starts to receive spooky messages and, with his new friend Sarah, he reluctantly begins to uncover clues to the boy's identity.

An eerie best-selling mystery from an award-winning writer combined with the talents of Peter England, the voice of Edmund in BBC Radio's Chronicles of Narnia.
