It is February 1839, and the ships of the United States Exploring Expedition are thrashing about dreaded Cape Horn, on their way to a rendezvous at Orange Harbor, Tierra del Fuego, on a crazy mission to be the first to find Antarctica. A sealing schooner hails the brig Swallow with a strange tale of a murdered corpse on an iceberg—surely a case for Wiki Coffin, half-Maori, half-Yankee "linguister," who is the representative of American law and order with the fleet.But circumstances are against him. As Wiki has been banished from the brig Swallow, which is commanded by his friend, George Rochester, to the sloop Peacock,where he is forced to battle racism in the wardroom, and vengeful sealers on the decks, the puzzle is surely too much even for this experienced sleuth. Then Wiki is tested even further when he is faced by a brutal murder on board. To solve this double mystery, Wiki is forced to make a voyage to the utmost fringes of the beckoning ice, on a mission more dangerous than any he has faced in the past.
