The Killer's Cousin.
By: Werlin, Nancy.
Ever since David Yaffe was acquitted of murder in the accidental death of his girlfriend, he has felt that for the rest of my life, over and over, I would have to convince everyone--including me--of my harmlessness. To escape media attention and the prying stares of the curious, he is sent to finish his senior year of high school in Cambridge, Massachusetts, where he lives in the attic apartment of his Aunt Julia and Uncle Vic. They receive him coldly, and his 11-year-old cousin, Lily, is openly hostile. (The apartment previously belonged to their older daughter Kathy, who died an apparent suicide at age 18.) With a haunting series of episodes--including a sporadic humming and a fleeting shadow--David begins to sense Kathy's eerie and powerful presence.
