Last of this series* (probably), aka ‘Farewell to Scotland’.
 
After making her bathe in the frigid North Sea, our Viking warrior lifted their Collie shepherdess captive up to his shipmates, who chained her to the deck between the rowing benches and the quarterdeck, where she sat hugging her knees as the Vikings finished their preparations for departure. As the Vikings row their longship away from shore against the wind, the girl realizes that she will never see her homeland again. She scrambles up and looks back over the gunwale of the ship, for the moment her nakedness forgotten.
 
As I’ve mentioned, I never finished writing this story…, but I did have in mind a happy ending, in which the Collie girl ends up joyfully mated to the young Viking who dumped her into the sea and integrated into the tribe rather than remaining a slave.
