Dead Man's Walk is a 1995 Western novel by American writer Larry McMurtry. It is the third book published in the Lonesome Dove series but the first installment in terms of chronology. McMurtry wrote a fourth segment to the Lonesome Dove chronicle, Comanche Moon, which describes the events of the central characters' lives between Dead Man's Walk and Lonesome Dove. The second novel in the Lonesome Dove series was the 1993 sequel to the original, called Streets of Laredo. Dead Man’s Walk was later adapted into a three-part miniseries of the same name, which aired in May 1996.
