Iceberg by Clive Cussler

This collection of excerpts, presumably from a novel titled "Dark Pitt 3 - Iceberg", follows the adventures of Major Dirk Pitt of the National Underwater and Marine Agency (NUMA) as he investigates the mystery surrounding a "ghost ship" embedded in an iceberg off the coast of Iceland. Initially dispatched with Dr. Bill Hunnewell to investigate a Russian trawler supposedly carrying valuable intelligence, Pitt soon uncovers a much darker plot involving a powerful organization called Hermit Limited and its ruthless leader, F. James Kelly, who seeks to control South and Central America. The narrative intensifies with attempts on Pitt's life by Oskar Rondheim, a key player in Kelly's scheme, leading to a perilous journey that reveals a deeper conspiracy, including the murder of Fyrie and Hunnewell. Ultimately, Pitt, aided by Admiral Sandecker and Jerome P. Lillie from the National Intelligence Agency (NIA), unravels the truth about Hermit Limited's true intentions and the involvement of Kirsti Fyrie, Kristjan Fyrie's twin sister, while confronting Rondheim in a climactic showdown.
