Mistress of Cliff House — Jeanne Stephens

THINGS THAT GO BUMP IN THE NIGHT...

Cliff House... an isolated mansion on the rocky coast of Maine. Cassie Underwood had come to care for her injured grandmother, then found herself in the middle of a family intrigue with potentially dangerous consequences.

Someone was walking the halls of Cliff House by night--Cassie was sure of it. But the intruder was clever and left no trace. Somehow she had to find out who it was. She just hoped against hope that it wasn't Daniel Reardon, the mysterious summer stranger who had won her grandmother's trust and was now suspiciously close to stealing Lassie's own heart.
