Cormorant Crag

Cormorant Crag, by George Manville Fenn, is the story of two young morons named Vince and Mike. They remind me very much of two young morons named Tom and Steve. Vince, like Tom, is not quite so much of an idiot as his friend, and Mike, like Steve, eventually learns to shut up and listen to his smarter, less dithery companion. Although Vince does quite a lot of dithering, too.
