Barry Cord was Peter Germano, who wrote extensively in books and television; I have found his work to be steady and satisfying. I picked this one up somewhere, half of an Ace Double with Merle Constiner's Killer's Corral., because I thought the plot featuring a telegraph wire crew was interesting. I've always found Constiner to be a pleasing western writer as well.
It was a good read, although lightly sketched in, in places; a frontier romance, and the appearance of the lead's old mentor on the wrong side of the law, are almost afterthoughts. But most Ace Doubles are quick, undemanding reads, and any are recommended for fans of such.
