"Librarian Jemima Jago is enjoying a peaceful summer in the Isles of Scilly - until a puzzling crime comes in with the tide... Between her work in Cornwall's oldest library and catching up with old friends over tea and chocolate biscuits, Jemima Jago is spending the season the only way she knows how: sunbathing, swimming and sailing. But her postcard-perfect summer is turned upside down when the body of well-to-do businessman Hermie Castleberry is found on the sweeping white sands at the foot of Candlewick Castle. Jem doesn't mean to get involved, but when her old flame Rhys Tremayne is arrested for murder, she springs into action to prove his innocence. With her gift for uncovering hard-to-find information, Jem discovers Hermie had been keeping secrets and ruffling a few feathers in the ordinarily tranquil islands. Did the quiet wife, the belittled business partner or the slimy salesman want Hermie out of the way? The discovery of a pair of silver gloves by little dog Buck could be just the clue Jem needs to crack the case. But can she catch the real culprit, and keep her heart in check, before the killer sends her down to Davy Jones' locker too?"--Provided by publisher.
