Two dozen award-winning and best-selling authors will gather for a ‘‘Murder at Sea’’ Caribbean cruise in October. The seven-day adventure, aboard Royal Caribbean’s new 16-story Allure of the Seas, hosts authors Don Winslow, Robert Ward, Stephen Hunter, Joanne Fluke, Lisa Jackson, and others. The festival includes panel discussions, author lunches and dinners, book signings, and an interactive whodunit with a professional theatrical troupe. The cruise departs Fort Lauderdale, Fla., on Oct. 16 and stops at Philipsburg, capital of St. Martin; Nassau, capital of the Bahamas; and St. Thomas before returning Oct. 23. Rates start at $1,349 per person, based on availability and double occupancy.
