At a conference at the Natural History Museum, Dempsey is unable to go through with the presentation, replacing his photographs with Isabel's kelpie drawing. On the way out, Dempsey informs Adrian that he fabricated his photographs before coming to Scotland, but Adrian, knowing the truth, understands. The Water Bailiff returns to Loch Ness, discovering Dempsey slipped his photographs into his bag during their conversation on the train. Dempsey returns to the inn, reuniting with Laura and Isabel, bringing the new bicycle with him. The plesiosaurs swim through the loch, accompanied by an infant.
