Tide's Gravity. Bracken Cove Mystery, #2

Julian Wesley was a man who believed the laws of physics were for other people. When he is found broken at the base of the local lighthouse, a spray-paint can of neon orange still in his hand, the town is quick to blame a local waiter with a grudge and a wrench. Even the local handyman, Jim Miller, seems ready to confess to a crime he didn't commit to protect a secret of his own. But Mave knows that gravity is a reliable witness, and the physics of the fall don't add up.
As she peels back the layers of a toxic fifteen-year friendship, she discovers a world of digital blackmail, high-tensile fishing line, and a "perfect" alibi built on a foundation of humiliation.
