The Mystery of the Jade Tiger — Carolyn Keene

Nancy's in California to investigate a series of break-ins at the home of her father's friend Terry Kirkland. A Vietnam vet, Terry came away from the conflict with a trunk full of memories. But unknown to him, the trunk also holds a mystery -- an exotic secret that now threatens to destroy his family.

A twisted trail of intrigue and corruption leads Nancy to a shocking revelation. The truth behind the burglaries rests with a soldier who vanished on a top-secret mission. But the trail of the tiger doesn't end in the jungle -- it leads right to Terry's door.
