Northwest Passage to Acock's Green

Ken is employed by a genial Irishman, Erroll McLaverty, to bring a canal boat back to Birmingham from near London. He takes Doreen and plans a romantic weekend. But two scruffy men, Appleby and Laing, are following the boat. Then Ken and Doreen hear strange sounds from the boat's cargo hold. They discover that an escaped convict, Alan Prendergast, is hiding in the boat - McLaverty had employed Ken to smuggle Alan back to his father, Walter Prendergast.
