In Island Nurse, little does Nurse Cherry realize when distinguished Sir Ian Barclay is rushed by his nephew Lloyd to Hilton Hospital, that her newest case will carry her north to misty, sea-beaten Balfour Island, off the rugged coast of wind-swept Newfoundland. "Sudden hemorrhage of a peptic ulcer," Dr. Joe Fortune had quickly diagnosed, and Cherry is assigned to care for the truculent but endearing old Scotsman. Cherry soon suspects that more than illness is worrying the peppery owner of the Balfour Iron Mines, and her suspicions only deepen upon their arrival at Barclay House on Balfour Island. True, there is trouble at the mines. But the mysterious actions of Sir Ian's erstwhile friend, Jock Cameron, force Cherry to conclude that trouble of even greater consequence is in the making. What hold does the industrialist Broderick have over Sir Ian? Who is "Little Joe" Tweed, and why does his trawler Heron ride at anchor off Balfour Island?
