Loch Ness, as everyone knows, has a monster. As a result, Loch Ness has fame,tourists and fortune. No wonder that there are long faces in the glens when a Flying Saucer seems to have killed, or at least injured, their prize possession. Donald MacDonald, twentythird Chief of Ben Nevis, who has seen the monster no less than twelve times, feels the blow personally. Then comes the dramatic news from the Outer Isles; a monster has been seen off Little Todday. Despite the scepticism of Paul Waggett, no longer a leading light in Todday's Home Guard, the schemes of the inhabitants of Great Todday, who see no reason why Little Todday should have all the publicity, the attentions of newspapermen and scientist, and Ben Nevis' crafty attempts to dispose of the rival attraction, the Todday Monster flourishes, to the personal and financial benefit of practically everyone on the twin islands.
