“The Beach House Murders” (*1/2 out of four) was an ill-conceived suspense thriller about a murder-mystery novelist (Brittney Dorey) who has a one-night affair with a stranger (CJ Hammond) who winds up dead and she becomes interrogated by the police and everyone around her (Ashli Auggilard, Kyle Williams, and others) becomes a suspect. So many red herrings and double-crosses and plot twists abound that by the end you’ll likely feel dizzy. Auggilard is good as her best friend but other performances are cartoonish and bland.
