A Night in the Mangroves - Donald Smyth - Bog

Three young teenage friends go on an overnight camping trip to a deserted island sitting off the coast of the Florida Keys, only to discover as nightfall drops a curtain of darkness over the landscape that they are not alone. Who's stalking the boys and what do they want? That will be the mystery that two detectives will try to unravel, forty years later, when they are called upon to investigate a cold case involving the discovery of two skeletons found hidden beneath a small, overturned boat in the densely overgrown interior of the uninhabited private island known as Shands Key.
