Karen Donovan no sooner marries bestselling novelist Philip Kaye when he leaves on a book tour, abandoning her at his Provincetown mansion with his sullen teenage daughter. Black-clad Jessie Kaye isn't exactly good company: When she's not skulking around, she's locked in her room writing in her journal, and her strangeness is a topic of local gossip. As autumn sets in, Karen befriends flamboyant local celebrity Bobbie Noble. But their plans to renovate Philip's house are sidetracked when Karen stumbles upon the diary of accused axe-murderess Lettie Hatch. It describes Lettie's boorish father and young, ambitious stepmother--both of whom would fall victim to a crazed killer. And the more Karen reads, the more she's convinced that Jessie, with her increasingly bizarre behavior, is channeling something sinister.
