A murder mystery/psychological thriller with an intricate, he-said, she-said plot. Good writing. Tracks the descent i to madness of the protagonists. Good plot/character development. Edge of the seat suspense. Some scenarios were improbable, but hey, it’s fiction. For me, a little too much time spent in the thick weeds of psychopathic, manipulative relationships, but that’s only me and, upon reflection, the book wouldn’t have worked without it..
