AT RIVER ARTS, NANCY'S PERFECTING HER PERFORMANCE -- UNDER COVER!
Set high above the river, the grand old Pennington estate is the perfect place for an arts colony. College students can work with established artists; and the owner, elderly Marianna Pennington, gets to keep her home. But when Rhoda Benton, the colony's director, gets a disturbing threat, Nancy and Bess start hunting for an elusive suspect.
From the owner's nephew, who wants to build condos on the property, to a handsome young artist determined to break all the rules, there's no lack of candidates. But Nancy's best lead comes from someone who wants to remain anonymous -- someone she'll have to meet at midnight at the edge of a cliff.
