The Gay Sisters.

Fiona, Evelyn, and Susie Gaylord are orphaned when their father, Major Penn Gaylord, is killed in World War I. Their half billion dollar inheritance is held up in probate for decades. A French charity claims that Penn made a later will before he died, leaving 10% of the Gaylord estate to it. Though the sisters are willing to give up the 10%, their real antagonist, Charles Barclay, wants their mansion, and the choice land on which it sits too.
