The Treasures of Weatherby - Zilpha Keatley Snyder

Set in a mysterious old mansion and filled with eccentric characters and a hint of magic, this mystery of humor is the newest work by three-time Newbery Honor winner Zilpha Keatley Snyder. Harleigh J. Weatherby IV leads a lonely existence in the vast Weatherby mansion under the watchful eye of his great aunt Adelaide -- until a mysterious girl named Allegra literally flies over the walls of Weatherby House and into his life. Allegra's intense curiosity about Weatherby House forces Harleigh to think about things he's always ignored, including the long-lost treasure of the first Harleigh -- which someone is trying to steal.
