Chief Superintendent Henry Tibbett of Scotland Yard is on holiday with his wife Emmy, sailing in the (Fictional) British Seward Islands. A chance acquaintance, Miss Betsy Sprague, goes missing on her way back to England, and sets off a hunt for not only the elderly lady, but for a woman she claimed to have seen... several weeks after that woman, Janet Vanduren, disappeared at sea with her fiance.
Henry gets involved in asking questions at the various marinas around the islands, and then undergoes a sudden and disturbing personality change that sends Emmy seeking shelter with friends while Henry goes off with new acquaintances met at a local club.
Henry had suspected Betsy had fallen afoul of people involved in a kind of modern-day piracy--drug runners trying to use the islands as a base to import drugs to the USA. But now Emmy must try to help Henry from a distance. And to make matters worse, there is a hurricane heading their way.
This is my first Patricia Moyes/Henry Tibbett story, and seemed far-fetched to me, although it became quite suspenseful in the later chapters. I enjoyed Emmy very much, but Henry remained a bit of a cypher to me. If I can find some of the earlier books in the series, perhaps I will be more taken with the characters. Otherwise, this was a twisty tale set in a beautiful part of the world.
