“Blue and Some Other Dogs” is a brilliant memoir about Graves’ Basque-Australian sheep dog. “Guns of a Lifetime” tells the stories related to the guns this octogenarian Texan has owned, beginning with a “rusted and cylinderless” revolver. “So here are the stories,” Graves writes. “They are not all ‘nice’ tales in contemporary terms. Political correctness, as presently defined, may be perpetrated here and there, though I hope no parts will seem like the maunderings of a Deep South redneck. But if they do, the hell with it. I am too old to fret about such matters.” It’s delightful writing from a treasure of a writer.
