About This Book
Two inventive cousins and their companions employ wireless telegraphy and experimental devices while based on an island and aboard a cruising vessel. They decode mysterious signals and confront a swift ram craft tied to a shady adversary with links to Yucatan, which triggers a broad maritime pursuit. The plot follows the use of ingenious apparatuses — gas guns, a hybrid air-and-land racer, and airships — in escapes, pursuits, and rescue attempts. Episodes range from shipboard danger and coded ciphers to a jungle voyage and a final rescue that uncovers missing relatives and a startling discovery.
