The Making of a Lawman — J.T. Edson

Waco was a product of the times. Left an orphan in a Waco Indian attack on a wagon train, he grew up among the large family of an impoverished rancher. Although treated as one of the family, some urge set him drifting at the age of thirteen. Even then he carried a gun, a battered but operational old Navy Colt. Four years later he wore a brace of Army Colts and bore a log-sized chip on his shoulder. His truculence might have sent him on the trail of Wes Hardin, Bad Bill Longley or other fast-handed Tejano boys running from the law after a killing too many.
Then fate stepped in. Waco met Dusty Fog, the fastest of them all.
