Over the next few days, we continued to find new little gems, with one beach more beautiful than the next. Anchored between Isla Pedro Gonzalez and Isletilla de Don Bernardo, we had a view of a stretch of white beach rimmed with coconut palms, their overlapping fronds thick, alluring fans of green swishing in the breeze. Only as we approached by dinghy did we see a small house. The sole occupant of this sweet little cove was an 83-year-old man, whose young wife had chosen to remain in Panama City. Walking the length of his beach at low tide, we gathered shells for our collection and one special treasure, a muricanthus, its spines intact and the black and white striations vivid.
