Powerful light sweeps over them: a searchlight from the British corvette that brought them here. The British sailors curse. Waterhouse levers himself up on his good elbow and sights down the hull of the U-boat, following the beam of the searchlight to a bizarre sight. The boat has been blown open just beneath the waterline, shards of her hull peeled back from the wound and projecting jaggedly into the air. The foul contents of the hull are draining out, staining the Atlantic black.
