Spring has sprung, the river is rising, and when Luann Dupree, the head of River Bend’s Historical Society, vanishes into the night, everyone in town is convinced she’s run off with her Internet Romeo. But her lifelong friend, Sarah Biddle, is convinced Luann is the victim of foul play. No one believes her—not even her husband, the local sheriff, so she turns to Helen Evans for help.

As River Bend’s resident puzzle-solver, Helen’s tackled many a local mystery before. So she agrees to help Sarah, even though she’s not so sure herself that Luann is really in trouble. But as the town’s flood waters slowly recede, dead fish and muck aren’t the only things Helen finds. She begins to uncover town secrets, false identities…and the very real chance that Luann might not be discovered alive…
