A fine follow-up to Swamp Water, which had a good critical reception and not as good a sale as it deserved. This is a direct, dramatic, tensed story of a derelict and his dog, Judas, the dog his boss didn't want, a black-hearted, bull-headed killer of a hound. The one thing Duff can do supremely well is train dogs, and he gets a job with a veteran pointer fancier, Hawthorne. There are two girls in the story, and both of them love him, -- Julie, Hawthorne's granddaughter, and Delia, whom he marries. There is much of the holding quality of the James Street dog stories, with less sentiment, more brutality, and decisive fascination as the story unfolds, with its pattern of field trials, kennels, and the individuality of two potentially great dogs.
