Summer has arrived in Inishowen and solicitor Ben O'Keeffe is greatly tempted by a job offer she's received from a law firm in America. Yet before making any life-changing decisions there is her friend Leah's wedding to attend at the newly restored Greysbridge Hotel, with its private beach and beautiful pier. It's the perfect location, everyone agrees, but the festivities are brutally cut short when a young American, a visitor also staying at the hotel, drowns in full view of the wedding guests. And when a second death is discovered the same evening, Ben finds herself embroiled in a real country house murder mystery, where all the guests are suspects.
