A Likeness in Stone — Julia Wallis Martin

An entire house, long submerged in the dark waters of a reservoir, unearths a startling find: the corpse of Helena Warner, an Oxford college student who disappeared twenty years earlier. For former homicide detective Bill Driver, it means the reopening of a case that, in his mind, was never really closed. And Driver thinks he knows who did it. But three of Helena's friends -- her cold former lover Ian Gilmore, her jealous best friend Joan Poole, and talented but institutionalized artist Richard Wachmann conspire to keep a decades-old, deadly secret from seeing the light of day...all the while, a killer continues to strike again and again.
