The Case of the Green-Dressed Ghost

Kester Lanner didn't know what to expect when he followed his mother's dying request to contact the mysterious Dr. Ribero, but he wasn't expecting to find his long lost father. Nor was he expecting to join the family business: catching supernatural spirits.
Kester is intrigued despite his fear, and finds himself drawn into an ancient ghost story that will test the entire agency.
He soon becomes enmeshed in a struggle with the spirit, who is so malevolent and haunting that his first real case might just be his last.
