The Three Investigators become entangled in the theft of a string of rare pearls and a fraudulent scheme involving family inheritance when they try to solve the mystery of a ghost's appearance in the old Green Mansion.
This is a perfect book for a 4th or 5th grader. Reading is advanced enough and subject is worthy of Alfred Hitchcock in the scary department. Fun book for a dad or grandad to share as a "remember when." Great for a winter or fall reading under the covers.
