Killigrew and the North-West Passage

1852: Arctic Ocean: Killigrew has volunteered for Arctic duty on the Venturer, part of Sir Edward Belcher's expedition to find Sir John Franklin's missing ships and the North-West Passage. Venturer becomes separated from the rest of the squadron and her glory-hunting captain decides to press on alone, deeper into the icebound bays of the Arctic seas. When the ship is trapped, the captain's hold on sanity begins to slip.
