The Visitor at Merville House — Sally Tyree Smith

Was Laurie Merville just being a possessive sister? Or was she right to disapprove of her brother Robbie's marriage to blonde, ethereal Cecelia Underhill Was she justified in resenting the presence of Cecelia's aunt, uncle, and cousin in Merville House?

From the first, Laurie sensed there was something odd about the Underhills, especially Cecelia and her Cousin Jason, with their unearthly bluegreen eyes and their strange, secret ways. Although Laurie herself adored Gabe Underhill, another of her sister-in-law's cousins, nothing could diminish her icy fear of Cecelia and Jason not after she had a swimming "accident" and was positive they had tried to drown her. Not after all the horror that followed!
