Three young sleuths discover who is haunting a mysterious old mirror--and why.

A hidden treasure is suspected, some criminals with a plan show up, and the Three Investigators end up right in the middle.

A wallet dropped by a scar-faced beggar sets the three investigators on the trail of bank robbers.

The Three Investigators are hounded by supernatural forces as they attempt to recover a stolen sculpture of a legendary wolf-dog.

A green ghost oozes through the walls of a crumbling old mansion, leading The Three Investigators to an open coffin and a grinning skeleton wearing a string of priceless Chinese Ghost Pearls. When the ghost disappears--along with the pearls--the sleuths are off on their strangest case ever!
