When Shiraz Jones joins Redcliff Marine Rescue to save lives at sea, she doesn't expect murder and mystery in the water. London socialite Shiraz Jones seeks refuge from her empty city existence and her husband's infidelity in the quaint English resort of Redcliff-upon-Sea. But life in the seaside town is nothing like her childhood beach holidays. And when her first outing with the marine rescue volunteers ends in tragedy, she's plunged into an ocean of secrets and lies. Now Shiraz must conspire with fellow crew member, Emily, to charm her way into Redcliff Manor and crash a seemingly innocent tea party. Because one of the guests drinking the Earl Grey and eating the home-made fruit cake is a killer, and they're about to kill again.
