I would not include Truman Capote's name on this list, because other works of his proved valid as well (Breakfast at Tiffany's, for example.) However I would propose the name of Ralph Ellison, whose Invisible Man received such deserved acclaim that he spent the rest of his many years trying to complete his second novel. the result was the unfinished (but still interesting) Juneteenth, decades in the making. Early success can be intimidating.
