Pre-Owned The Christmas Thief (Paperback) by Mary Higgins Clark, Carol Higgins Clark

The folks who picked a beautiful eighty-foot blue spruce from Stowe, Vermont, to be Rockefeller Center's famous Christmas tree don't have a clue that Packy Noonan, a scam artist just released from prison, hid priceless diamonds in it more than twelve years ago. But when Packy learns that his special tree will be heading to New York City the next morning, he knows he has to act fast.

What Packy does not know is that Alvirah, everyone's favorite lottery winner turned amateur sleuth, and savvy private investigator Regan Reilly are visiting Stowe with their friend Opal, who lost all her lottery winnings in Packy's scam. And just when they're supposed to head home, they learn that the tree is missing . . . and that Opal has disappeared.
