Dark Labyrinth — Lois Barth

When Jessica was urgently summoned out into the night by the authoritative voice of a police lieutenant, she knew something tragic had taken place at the Hermitage, her cousin's rambling in the northern New England hills. Her cousin's tragic death did not appear to be an accident. And while Jessica tried to decide who at the Hermitage could be a murderer, she found herself under suspicion on the one hand and threatened on the other by someone -- the guilty one? -- resolved to still her mind and her tongue.
